What makes Ably special?
Ably (www.ably.io) provides the serverless infrastructure developers need to build applications, services, and APIs for the realtime Internet. We operate a high-performance, globally-distributed data stream network that delivers more than two billion messages each day. And we’re growing fast. To put things into perspective, Twitter sends just 500 million Tweets per day.
Our customers range from global enterprises - such as HubSpot, OfferUp, and Tennis Australia - to pioneering startups powering complex air traffic control systems for drones. Organizations choose Ably because we make hard system architecture and infrastructure problems easy.
If you don't know what a Site Reliability Engineer is, we recommend you first read Google's definition of a Site Reliability Engineer, which we are in agreement with.
As an engineer in our Site Reliability Engineering team, you’ll build solutions to enhance availability, performance and stability of the Ably platform as well as developing new network services whilst automating away repetitive work. If you're excited by working on truly complex problems at internet-scale with other smart engineers, you'll enjoy working at Ably in this role.
Our infrastructure stack currently comprises of mostly
- Infrastructure languages: Ruby, Go, Bash.
- Service languages: Go, Elixir, Node.js and some C.
- Mostly AWS based, but we are experimenting with supporting other clouds.
- Architecture: Exclusively Docker containers for all services, servers are immutable, ephemeral and disposed of frequently, datacenters (circa 20 and growing) are isolated and autonomous, critical shared services always have redundancy baked in; manual configuration of any infrastructure is a smell.
- Data services: Cassandra (our realtime datastore, 3 regions, 6 data centers), Influx, Elastic, Kibana, Grafana, etc.
- Web site: We use Rails & Heroku for simplicity. The web service is not part of our "core product" and thus has lower uptime requirements.
Day to day you can expect to be working on:
- Writing Ruby code for our infrastructure automation, orchestration, configuration and continuous integration testing of our infrastructure.
- Making extensive use of a wide range of AWS services.
- Managing and developing out our continuous integration services.
- Optionally, writing Go code for some of our routing layers and infrastructure services.
- Collaborating with the wider engineering team to design, discuss and implement new features and services.
- Diagnosing and fixing bugs in all areas of our platform.
- Contributing to open source projects that we support or use in our products, including our open source client libraries SDKs.
- Salary range: £50k to £85k.
- Holidays: 25+ days excluding national holidays.
- Flexible working environment combining remote and/or onsite working.
- Skills development is inherently part of the job. You will be working with a wide range of technologies and solving distributed systems problems.
- Our customers are themselves developers - you will be helping those customers solve their own technical challenges.
Engineering at Ably means working on a cutting-edge product and contributing to genuine innovation that’s shaping the future of the Internet. You’ll have the freedom to take ownership of the code and full development lifecycle of features you work on - from initial commit to global rollout. You’ll learn with the best and be part of a dynamic team. And we realize people don’t fit into boxes. Everyone at Ably has the autonomy and flexibility they need to do their best work, experiment on a daily basis, and improve their skills.
Join us now and you’ll be in early at a business going places, learn new things everyday, work closely with the founding team, and, honestly, have loads of fun.
- Experience: You must have a minimum of a three years of professional experience with Ruby, broad knowledge and experience working with AWS (or other cloud providers), a solid background working with Linux, and understanding of network protocols. If you have any experience with Go or distributed systems, this is a benefit but not required.
- Open source: We prefer developers who have contributed back to the open source community, even if those contributions are small.
Salary range £50,000 — 85,000
