About the job
Karfu is seeking a full-time Back-end Software Engineer to take our platform from a prototype in private beta, through into public beta, followed by a full commercial launch of the product.
We are now looking for a Back-end Software Engineer with relevant experience who can join our small team, work collaboratively to build the next phase of the product and help us achieve product-market fit. The ideal candidate will be someone who has learned their craft working on a range of software development projects and who is ready for the next step up.
You will have primary responsibility for ensuring our services, data and infrastructure are developed and optimised to allow Karfu to deliver a stand-out consumer website.
You’ll do this through working directly with our Founding team, Karfu employees, technical suppliers and marketplace providers, in order to understand, prioritise and establish software development requirements. You’ll need to find innovative solutions as we iterate and grow, including how best to evolve the architecture and integrate new features into the website platform as we scale.
The role will initially focus on integrating a variety of first and third party data, available via APIs and batch CSV downloads. This data will need to be stored and transformed for Karfu’s use, to enable our unique result display to access the required data. You will then play a significant role with our CTO and Front-end Software Engineer to build the infrastructure to support our product roadmap through beta testing to launch. This will include ongoing monitoring and developing solutions to improve website performance to ensure the Karfu product runs as quickly and efficiently as possible from a consumer perspective to enable the best user experience.
You will have the opportunity to shape the product roadmap and be a key contributor to the ongoing development of the product vision and proposition. If you are successful, you will leave a lasting impact on the finances of UK consumers and help inform consumers about more sustainable mobility choices.
You will work across a combination of proofs-of-concept and investigations, large strategic projects, improving our internal processes and some smaller tactical work. You will work directly with our CTO, a Front-end Software Engineer and a Project Manager to plan functionality, deliver it and prioritise product backlogs and monitor technical debt. You will also need to understand and be able to take charge of DevOps in the absence of our CTO.
You're an expert in APIs, from both a design and build perspective, as well as integrating numerous APIs and data feeds from multiple 3rd party sources. You will need to work with our technical suppliers who are providing key data to the platform, as well as marketplace providers who provide mobility products and services.
You will display an understanding of how a user will interact with the backend interface, making sure any tools are easy to use from the point of view of an editor; we don’t want someone to have to have a PHD on how the platform works in order to make content updates.
You will regularly review software development processes and evaluate results to inform ongoing learning and improvement. You will keep up to date with emerging digital technologies and best practice in software development, identifying where we can improve ways of working, innovate and add value for our customers.

Karfu, currently in stealth, is a B2C technology start-up in the mobility sector.
We define Mobility as the technologies, products, vehicles and services that enable people and goods to move around freely.
Karfu is an impartial online platform designed to help consumers save money and discover the financial and environmental costs of their ‘mobility’ choices, including vehicles from cars to scooters, across access options from ownership to usership.
The product is currently a desktop and mobile website. Mobile apps (iOS and Android), and a B2B proposition will follow in due course.
We have just completed our second external funding round. A full explanation of the company, strategy and product will be provided during the interview process.
Karfu's founding principles are to be transparent, responsible and sustainable. We are a certified Pending B Corp and are committed to promoting diversity and inclusion.
How are we committed to promoting Diversity and Inclusion
Diversity means difference, specifically the range of human differences within a group of people across the three categories below:
Demographic (age, race, gender identity, sexual orientation, physical resources)
Experiential (economic or social position, education, occupation, faith, abilities, dependents, caring responsibilities)
Cognitive (how we approach problems and think about things.)
Karfu is committed to hiring people with as broad a range of these differences as possible.
Inclusion is the act of making someone feel part of a group, which involves people’s well-being at work, safeguarding people’s mental and physical resources, and championing rights and cultural differences all of which collectively help people to succeed at work.
By its nature, inclusion is difficult to measure in the workplace. Karfu’s aim is to create an inclusive environment that allows individual contribution to matter and employees are able to perform to their full potential, no matter their background, identity or circumstances.
Benefits of working at Karfu
All positions at Karfu include:
A competitive salary including statutory pension
Stage appropriate equity compensation, via our employee option scheme
25 days of paid annual leave excluding bank holidays (pro rata for PTE employees)
You are looking for a place to belong and grow
We are looking for our first hires outside the Founding team. We want people who are passionate about what we are doing and want to help us grow the company over the next decade. We want committed people who share our values and our vision.
Purpose, not just profit, drives you
Karfu is a (pending) B Corporation. Rather than just words, we wanted to prove our commitment to taking action by having legally enforceable standards to live up to. We care about sustainability and the impact Karfu could have on consumer decisions. We appreciate diversity and inclusion challenges which are reflected in our hiring policies and our internal culture. We want to be a responsible business that helps across local, national and global communities.
You know about vehicle purchase methods and how they work
If you know your PCP from your PCH and could you create a breakdown and assess whether one is a good deal or not relative to the other, this is the perfect job for you. We are looking for someone who will bring in these specific skills and can hit the ground running. Alternatively, if you understand consumer finance, or the ins and outs of how loans, mortgages or the cycle to work scheme operate, we’ll work with you to transfer these skills to working with Karfu.
You are passionate about mobility
You feel there are unique challenges and opportunities for mobility products and services and you love helping people find answers that are right for them. You’re intrigued by Electric Scooter trials. You are familiar with businesses from Citymapper to Zipcar. You are as happy on a bike as a bus or a train. You are interested in all forms of mobility and you see this continually expanding industry getting more exciting, not less. It’s where you want to build your career and your expertise.
You believe in impartiality
We believe in a level playing field for providers to compete against each other. Think the BBC, trying to see different options from both sides, rather than Google focusing on working with the highest bidders and making it impossible for a small business to compete.
You are reliable and you care
As an early stage start-up, you will be working closely with the Founders and we expect you to share the same level of enthusiasm and professionalism. We adopt a merit-based approach in our company. If you care about your performance at work, taking your role, time management, output and contribution to the team and company seriously, you’ll enjoy working with us.
You have a start-up attitude
You have a keen appetite to optimise, test, build and learn. You have a flexibility that means you can fill in for others if they’re away or help other members of the team when they need it. If you don’t know something, you don’t wait to be told to look it up. You are proactive both in work and in improving your own skill set outside of it.
Useful to know
We are recruiting a number of new employees who you will work with, including:
Front-end Software Engineer (FTE)
Project Manager (PTE)
Product Designer (PTE)
Content Editor (FTE)
Marketing Executive (FTE)
We won’t be fully remote forever
Whilst these roles will be primarily remote, we are planning on having a flexible office or workspace in London at some stage in late 2021 / 2022, dependent on COVID-19 related developments
We currently envisage attendance will be at least 1 day a week in person, with preferred office locations near or between Clapham Junction and Waterloo, with the duration and location subject to change
This will require you to live a commutable distance from central London in case we decide to increase the amount of weekly attendance at a later date.
However, we will consider candidates with exceptional CVs from elsewhere in the UK, who seek a remote only role, so please do not be deterred from applying
We understand and care that you have a life
Whether you have a family, caring commitments, or other responsibilities outside of work, if it is important to you, it is important to us.
Our Founding team appreciates juggling work and life is not easy. We will endeavour to treat you as we would like to be treated ourselves when things don’t go to plan.
We are a sustainable start-up and we run lean
We are focused on saving consumers money. It would be irresponsible of us to be frivolous with our own investment funding with that mission in mind.
Instead, we’ll focus on things that we feel are important to employees, like a challenging role that will push you, living wage salaries, pensions, benefits and fair work / life balance, rather than ensuring you have a new t-shirt every time we change our logo, or a professional table tennis table.
If necessary, a suitable laptop will be provided, with your views and project requirements in mind. However, we are happy for you to use your own personal computer equipment.
Your questions about accessibility
If you have any questions about accessibility, or are concerned about any Karfu company policies that might affect your ability to do a good job, please get in touch at [email protected], using a non-personally identifiable email address if at all possible.
How to apply
Apply via Unicorn Hunt or send the below to [email protected].
Provide a CV (no more than 2 sides of A4) without a name or date of birth, to help us keep applications on a level playing field.
Let us feel your passion. Tell us why Karfu over every other company and why you are right for us in no more than 100 words in your application email.
Finally, we’d like applicants to send us something that showcases your skills that we can view or test, for example, a link to:
Software Development - your GitHub or Stack Overflow
UK applicants only, please
At the moment, we are headquartered in the UK.
For this reason we are only looking for UK-based candidates with a UK work permit to join us.
There are no sponsorship opportunities at Karfu.
Following initial shortlisting, there will be 3 stages, which may vary in order:
At least one strategic or tactical test

Note to Recruitment Agencies
No recruiters or agencies, please.
Karfu does not accept unsolicited CVs from recruiters or employment agencies in response to any of our live roles on our career pages on the Karfu website, company branded social media presences (including Facebook, Instagram, Twitter and LinkedIn) or external recruitment platforms.
Karfu will not consider or agree to payment of any referral compensation or recruiter fee relating to these unsolicited CVs.
