Job description

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 a frequently changing deployment footprint and highly value flexibility in both the infrastructure and our team.

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, flexible 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.

Interview Process

1. Intro call (30 mins) - your background + interests
2. 1st Technical interview (30 mins) - live systems wrangling and code review
3. 2nd Technical interview (60 mins) - deep dive technical questions
4. Full assessment day (10:00–5pm) - a one day systems engineering exercise designed to be similar to the real work we do in the team. Meet some of the team, see the office, have a nice lunch (on us).

• Extensive experience as a DevOps engineer, linux focused
• Security, user management, auditing, provisioning
• Configuration management, specifically Ansible
• Strong AWS skills: EC2, VPC, RDS etc
• Networking experience that includes AWS VPC multi region networking, routing, VPN and general network security competence
• We have an extensive set of monitoring and alerting tools which you would take day to day ownership over. Prometheus & Grafana are key technologies here
• Fluency in bash and python for automation work.
• DB admin experience with Postgres
• Proven experience within the financial, trading or gaming sector. We handle a lot of real money and mistakes can be costly.

• Participation in the uncapped company bonus scheme
• 10% matched pension contributions
• Private healthcare insurance
• Long term illness insurance
• Gym membership
