Job Description:

Smarkets is a betting exchange for sports and political events that has handled £29 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.

The Role

As a Tech Lead in our Engineering organization, you are leading a team of software engineers who build, manage, and maintain the services that power Smarkets' core product - Exchange.
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 Team

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 C++ 20, Erlang and bits of Python but we are in the process of transitioning those to Rust. 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. We use property-based testing and marge-bot.

In details, you will:

• Engineer and optimize exchange solutions, focusing on but not limited to scalability, low latency, reliability, monitoring, security and automation.
• Drive sprint planning, including proper scoping of tasks, and execution of the roadmap delivery goals, working alongside our Product Management function
• Directly manage a team of engineers, from junior to seniors as well as hire great people and keep them happy, motivated, and challenged
• Ensure the career growth of the engineers in your team as they advance in seniority
• Set the standard for quality engineering, including improving our engineering processes, to keep our level of excellence high
• Collaborate with other leads and engineering managers, and other stakeholders in the implementation and future development of product roadmap.
• Represent the team in cross-functional meetings and internal events
• Be proactive during incident management with hands-on troubleshooting.
• Be the champion of the stack by demonstrating first hand how to implement functionalities in the right way, with an eye to the horizon and your mind on the present
• Articulate the company vision and strategy to the team; the “why”, the business case, context, benefits any constraints etc.

We’d love to talk if you have:

• Previous experience leading and mentoring exchange-focused engineering teams.
• Proven leadership skills, and capable of building and managing technical teams.
• 6-8 plus years’ experience in designing, developing, and implementing cloud-distributed systems.
• Can demonstrate deep knowledge in running services in cloud microservice environments and hands-on experience with Kubernetes.
• Familiarity with AWS cloud.
• Familiarity with observability principles and tools (Grafana, Prometheus, Sentry Elasticsearch, Jaeger)
• Excellent planning and communications skills and able to lead conversations with development and product teams.

Preferred Skills and Experience

• Proven track record working in agile environments
• 5 years’ demonstrable experience with CI/CD pipelines and infrastructure as code (IaC) using tools like Terraform and Gitlab CI.
• 8+ years of experience building services for low-latency and high-scale products.
• 8+ years of experience working with a compiled language (Rust, C++, Go, Java, etc)
• Previous experience leading a team technically or directly
