Senior Backend Engineer

We’re one of the largest prediction market platforms in the world, focused on sports. This year we’re on track to surpass $1B in volume, with 300% year-over-year growth. Our goal is to become the leading peer-to-peer betting platform globally, competing directly with the biggest players in the space.

We’re a small team building a low-latency, highly scalable sports betting exchange that already powers over $1B in annual volume. We’re looking for a strong systems/backend engineer to help take our infrastructure to the next level and expand what we offer.

We’re fully remote, but we get together in Toronto every couple of months for on-sites, and occasionally do a few days of in-person work sessions at a co-working space. You’re expected to be able to attend these. You’ll report directly to the CTO.

What you’ll do

• Work as an individual contributor solving hard backend and systems problems
• Build core exchange infrastructure: design and implement low-latency, high-throughput trading and matching systems in Go
• Optimize for speed and scale: profile, tune, and debug performance-critical systems with a focus on latency, throughput, and determinism
• Design robust systems: develop efficient algorithms and data structures, and build scalable, event-driven systems (Kafka or similar)
• Expand the product: support new markets, trading features, and capabilities
• Own reliability and correctness: improve security, availability, and performance through thoughtful design, testing, and operations
• Contribute to engineering quality through design and code reviews

What we’re looking for

• 3–10 years of professional software development experience
• Strong experience with AWS (or a similar cloud platform)
• Experience building and operating large, complex APIs with strict uptime and latency requirements
• Familiarity with event-driven, data-intensive systems
• Strong ownership mindset and accountability for outcomes
• Comfortable debating ideas and pushing for the best solution

Benefits

• Competitive salary
• Full benefits
• New hardware setup

Interview process

Our process includes a few technical and fit interviews, followed by a paid weekend working session with a senior engineer. You’ll work together on a real problem so we can both get a sense of how we collaborate. If that final step isn’t something you’re open to, this role likely isn’t a fit.
