- Design, develop, and maintain high-performance platform services including API gateways (FIX, WebSocket, REST), and the core libraries that product teams across Talos build on. - Build and evolve Aeron-based messaging infrastructure for reliable, low-latency communication. - Tackle hard distributed systems problems end-to-end: ordering and determinism guarantees, zero-downtime deployments, active-active architectures spanning cloud regions, and crash-consistent recovery. - Work cross-functionally to ensure platform primitives meet the throughput and latency requirements of real-time trading workflows, including market data distribution at scale. - Provide product teams with reusable service infrastructure to build scalable, reliable, and cost-efficient services.

- 7+ years of backend engineering experience with deep proficiency in Go, C++, Java, Rust or similar systems languages. - Demonstrated ownership of large-scale distributed systems, from initial design through deployment, scaling, and long-term operations. - Strong systems-level fundamentals: concurrency primitives, memory layout, I/O models, database design, network protocols, and the performance implications of each. - Experience designing systems with stringent correctness guarantees — ordering, consistency, durability — not just ones that work under normal conditions. - Own projects end-to-end: take work from problem definition through design, implementation, and rollout, and see it through to completion without needing to be chased. - Track record of leading technical decisions: navigating ambiguity, defining architecture, making meaningful trade-offs, and bringing a team along on the reasoning. - Comfortable operating at multiple levels of abstraction, from API contract design down to diagnosing latency spikes at the socket or disk layer.

- Retirement plan contributions - Unlimited Vacation + a PTO bonus: Employees that take 15 days of vacation, with 5 days being consecutive, receive a $2000 USD bonus. - Bonus and stock ownership - Medical, dental, and vision insurance - Paid parental leave for 20 weeks, after 1 year of service - Global offsites and team outings - A one-time stipend towards at-home office set-up for all employees - A wellness credit of $50 accrued monthly, to go towards things like gym memberships, ski-passes, and work out classes. - A lunch credit of $25 USD towards lunches for days in-office - Donation matching up to $100 USD annually - Other in-office perks: Catered lunches on Tuesdays, snacks, and drinks
