Senior DevOps Engineer

At Longshot Systems Ltd we build advanced platforms for sports betting, analytics and trading.

We’re looking for a Senior DevOps Engineer to join our platform team. We’ve got a medium sized deployment that handles trading and connectivity with sports betting platforms globally. We have several internal teams with different infrastructure requirements and everything has to work well together and be centrally managed. From backtesting to real time trading systems to long running backend services, we have strong internal support for a wide array of systems critical to the business. You would own this infrastructure.

We’re hosted on AWS and we’re in the process of an infrastructure evolution with a strong focus on automation and repeatability to support the next phases of growth for Longshot.

Our core systems handle thousands of trading signals per second, all of which must be processed and potentially acted upon with minimal latency. We have similar problems and constraints to high frequency trading shops, but in the sports betting world.

You'd be working closely with the CTO and the development team to support our production & development trading infrastructure, develop new infrastructure and detect, diagnose and help solve performance and stability issues in applications, networks and operating systems. You should be happy wading through metrics, packet dumps and logs to find and solve issues and then automate them away for next time.

The ideal candidate will be highly autonomous and enjoy generating new, innovative ways to tackle problems and suggest improvements to existing methodologies. We’ll give you a lot of flexibility and freedom to explore good solutions.

We are a hybrid working company, working Thursdays in our London (Farringdon) office and flexible the rest of the week. Our typical working hours are 10 am to 6 pm UK time, Monday to Friday, but we support flexible working and trust our team to manage their own schedules to meet their goals.

On call - we do not have a 24/7 rota, but we do have a best efforts, compensated out of hours on-call system you would be part of. Responsibilities here would be shared amongst the wider platform team.
