wintermute-trading - Product Engineering - Tech Lead

• 8+ years of software engineering experience, with at least 3 years in a technical leadership role (tech lead, engineering lead, or similar). • Proven track record of making architecture decisions for complex, data-intensive applications — ideally in trading platforms, financial services, or other high-throughput/low-latency environments. • Deep experience building and scaling real-time, high-data-volume systems (e.g., trading dashboards, live data feeds, streaming analytics, order management systems). • Strong command of the modern frontend stack: TypeScript, React, Node.js — and the ability to evaluate and adopt new technologies as needed. • Hands-on server-side experience: building and maintaining backend services, APIs, and data pipelines using languages such as Node.js, Python, Go, or similar. • Solid understanding of end-to-end system architecture: APIs, microservices, event-driven architectures, WebSockets, message queues, databases, and how frontend and backend systems work together in high-performance environments • Experience with infrastructure and DevOps fundamentals: CI/CD, cloud platforms, CDN, monitoring/observability, and deployment strategies. • Strong understanding of security best practices (OWASP, authentication/authorization patterns, secure data handling) — especially in a financial context. • Experience hiring, mentoring, and growing engineers — building a high-performing team, not just managing one. • Experience at a trading firm, fintech, or any environment where milliseconds matter and data volumes are extreme. • Familiarity with algorithmic trading concepts and financial market infrastructure. • Experience with performance optimization at scale — profiling, caching strategies, efficient rendering of large datasets. • Experience with backend technologies beyond Node.js (Python, Go, Rust, or similar) for performance-critical services. • ## Write to us if you: • Love making hard technical decisions and seeing them pay off at scale. • Get energized by building high-performance systems that handle serious data volumes. • Want to shape the technical direction of a product team, not just execute on someone else’s plan. • Are passionate about engineering culture — code quality, mentorship, and continuous improvement. • Are curious about algorithmic trading and financial markets. • Are determined, ambitious yet humble, willing to lead by example. • Thrive in a meritocratic environment where impact matters more than titles. • Prefer ownership over process — you’d rather build the right thing than follow a playbook. • Enjoy working in-person with your team (not fully remote). • ## Tip for a successful application: • Only apply if you are genuinely excited about leading a technical team in a fast-paced trading environment; this is not a people-management-only role — you will be deeply technical. • Write us a short, honest, and direct message about why you want to lead engineering at Wintermute. Tell us about a hard architecture decision you made, what the tradeoffs were, and how it played out. Do not send generic applications — we are looking for authentic technical leaders who share our values and ambitions. • We will arrange a UK visa sponsorship and help with relocation to London.
