Job description

✨ 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, Eric Schmidt’s VC firm, and angels from 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 – we are looking for folks with 5+ years of work experience in Python, ideally in fast-paced or entrepreneurial environments. Bonus points if you’ve contributed to open source.

💻 What you’ll do

• You’ll build – You’ll contribute across our tech stack - our SaaS product, data pipelines, AI agents, telemetry infrastructure, and more.

• 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 set and maintain standards and mentor future team members.

🙌🏾 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” enough—please apply. Great talent doesn’t always fit neatly into a checklist, and we know that underrepresented folks often underestimate their fit. We care more about the ideas you bring, your ability to learn, and your enthusiasm for the work than about whether your resume matches every bullet point. The company we’re building will shape how financial systems work for years to come. That’s why we’re committed to building a team with diverse voices, perspectives, and lived experiences. Diversity isn’t a nice-to-have—it’s a must-have. And we’d love to have you be part of that.
