At Longshot Systems we build advanced platforms for sports betting analytics and trading. We are looking for a Senior Software Engineer to join the team that owns and develops our trading platform. Longshot is a small, focused company and so the role suits someone who can architect and implement whatever is needed to meet our next product, performance or stability goal. The team owns the technical standards and coding guidelines, CI/CD, observability and security. This role suits someone who wants to ship features and contribute to the wider technical excellence in the team and platform.
The trading platform at Longshot handles integrations with many bookmakers and exchanges worldwide. It normalises and combines the global odds data for many sports and makes it available internally for strategies to trade on. We handle thousands of odds updates and trades per second and have very strict bounds on latency, correctness and overall quality of the feed and trading. You will be at the heart of this team: integrating more trading venues, optimising key parts of the platform, and making trading safer and faster. We also maintain a significant historical data repository and support wider trading and research efforts around the company.
Our key platform systems are all in Golang, with message buses and databases at the core of the architecture. You don’t need to be fluent in Golang, but it would help. It’s easy to learn and we have a team full of experts able to teach you. 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. We support flexible working and trust our team to manage their own schedules to meet their goals.
Interview Process
- Intro call (30 min) – your background and interests
- 1st Technical interview (30 min) – live code review and pair programming
- 2nd Technical interview (60 min) – deep-dive technical questions
- Full assessment day (10:30 – 5 pm) – a one-day systems programming exercise similar to the real work we do in the team, meeting some of the team, seeing the office, and having a lunch on us
Requirements
- Masters or PhD in a quantitative or technical subject (e.g. Maths, EE, Physics, Comp Sci) from a top university
- Deep experience building mission-critical distributed systems (finance, gaming, telco, ad-tech, etc.) where throughput, correctness and availability are hard requirements
- Startup experience: Proven track record shipping products in small, fast-moving teams
- Proven track record delivering and maintaining production systems in at least one systems language (Go, C++, Rust, Java, C#, etc.), with clear, idiomatic designs
- Architecture & design: Able to reason about trade-offs and produce clean, evolvable service boundaries
- Cloud & DevOps: Comfortable working in AWS, Linux and wrangling build pipelines. We have dedicated DevOps people, but you do need to be competent in the core skills here
- Fluent written and spoken English. Communicating with the team is as important as the technical work. You need to be able to effectively collaborate on everything from low-level details to long-term strategic planning
Nice to have
- Trading, market-making or exchange experience
Benefits
- Competitive bonus scheme
- 10 % matched pension contributions
- Private healthcare insurance
- Long-term illness insurance
