Staff Full Stack Engineer (Python + JavaScript)

✨ Overview Tetrix is a fast-growing startup on a mission to empower institutional investors to confidently invest in alternative markets (think Bloomberg, but for private markets). Our AI-native product transforms messy, unstructured private market data into real-time insights, combining automated document retrieval, AI-powered data extraction, and on-demand portfolio analytics - all in one seamless platform. We are growing quickly to becoming a category-defining product, and are working with some of the world's leading capital allocators. This is a unique opportunity to join a talented and driven team that wants to build next-generation infrastructure in financial markets, and is backed by stellar investors that include Innovation Endeavors, White Star and angels from Goldman Sachs, BlackRock, CPPIB, SoftBank, Lending Club, and Plaid. 🤷🏽️ Who we are We are a small but mighty startup with deep industry background and expertise in both financial markets and modern technologies. We’ve worked hard to build a culture of trust, high ownership, and curiosity - where everyone feels empowered to contribute, challenge ideas, and grow together. We are led by our two co-founders, Olivier (CEO) & Naunidh (CTO), who met on the first day of school whilst pursuing their MBAs at Stanford and co-founded Tetrix in the Summer of 23. 🤞🏽 Who you are You’re proactive and hands-on – someone who takes initiative, figures things out, and keeps things moving. You learn and adapt quickly – someone who approaches problems with creativity and energy, and is resourceful, adaptable and excited by tough challenges. You’re customer-oriented – whether you’re making backend decisions or improving UI, you keep the customer in mind and push for delightful experiences. You’re collaborative – someone who values transparency, good communication, and knows that the best outcomes come from working well with others. You’re experienced and thoughtful – 10+ YOE in Python and JavaScript. You have strong technical leadership experience, including architecting complex systems, mentoring engineers, and driving best practices in fast-paced or entrepreneurial environments. Bonus points if you’ve contributed to open source.   💻 What you’ll do You’ll build and lead – You’ll contribute across our tech stack - our SaaS product, data pipelines, AI agents, telemetry infrastructure, and more. Our stack is primarily Python and JavaScript, but it’s evolving fast. You’ll set technical direction and make high-impact architectural decisions. You’ll brainstorm – We’re not looking for someone to just take tickets—we want you in the room helping us shape product direction and tech strategy. You’ll work with clients – From pitching customers, to designing features, to soliciting feedback, you’ll do some non-engineering work. We believe in all-rounded team members. You’ll champion best practices and guide others – As a B2B SaaS platform, our technology needs to be secure, robust and scalable. You’ll help define and maintain standards, mentor engineers and help build a high-performing team as we grow.   🙌🏾 Why join us You’ll have real impact - We are at an inflection point - your work will directly shape our product, team, and company trajectory. You’ll be supported - We’re committed to helping you do your best work and grow both professionally and personally. You’ll be rewarded - Competitive salary, meaningful equity, and benefits including unlimited vacation, healthcare, and retirement plans. You’ll grow fast - We move quickly, think deeply, and believe in learning through doing. You’ll be surrounded by smart, driven, kind people. You’ll have fun - Shipping is inherently fun, winning is even more fun, and when all else fails, we have plenty of fun in and out of the office. 🫶🏽 One more thing If this role sounds exciting but you’re second-guessing whether you’re “qualified”
