Senior Software Engineer - Distributed Systems

Smarkets is a betting exchange for sports and political events that has handled £37 billion in traded volume since 2010. Our goal is to fix the sports betting industry by creating a transparent platform that offers the best value for users, with not only the best odds but also the latest technology, alongside an amazing customer experience.

As a Senior Software Engineer in our Engineering organisation, you are leading a team of software engineers who build, manage, and maintain the services for Smarkets' core exchange functionalities that power our main products Exchange and SBK. You are here to help organize the direction of your team, guide their career growth, and ensure that we’re building the right stack to power the future of our products.

You will be responsible for leveraging your team to ensure that our services are responsive, scalable, and performant.

Ultimately, you will be working alongside your team of engineers, engineering managers, and product managers, to drive the complex technical projects that help deliver the Smarkets product roadmap.

The successful candidate will initially take over technical leadership of the team and will transition to a tech lead manager position later.

We design, develop, deploy and operate the real-time distributed exchange systems that run 24/7 all year long. Our responsibilities include order matching, pricing feed, activity journaling, settlements, risk management and dissemination of market data. We care a lot about reliability, fault tolerance, throughput, and latency. Our high availability requirements dictate emphasis on testability and reproducibility alongside monitoring and alerting.

Our tech stack includes Rust (low-latency distributed services), Python (property based testing and scripting) and parts written in C++ and Erlang which are gradually decommissioned. We use Postgres as our main DBMS technology and Apache Kafka for queuing. Our CI is based on Nix and we ship daily to production.

You will be joining the team in a pivotal moment as we are transitioning from a monolithic architecture of our core exchange infrastructure to horizontally scalable architecture which can handle 10'000+ orders per second.
