Member of Technical Staff -- Founding Software Engineer

We're seeking exceptional software engineers who can build complex, high-performance backend systems that power our AI-native products for finance. You'll work closely with the founders, implementing scalable infrastructure and services that enable cutting-edge AI advances to be delivered reliably at scale.

Twenty Labs is an applied research lab working on augmenting knowledge workers, starting with finance. The penetration of AI in finance is still limited and we want to be the company that delivers AGI to finance through our product, Compound https://getcompound.ai/ (@getcompoundai https://x.com/getcompoundai). Some product videos can be found on YouTube https://www.youtube.com/channel/UC0Gk06k3JN0rkSBWiLsMx2g.

You'll be joining a highly technical founding team, including leading researchers and engineers from Google DeepMind/Brain and Microsoft who pioneered research in language models, shipped GenAI products to billions in production, paired with domain expertise from top finance and consulting firms (Coatue, Bain, Y Combinator).

• Have experience implementing complex, high-performance backend systems from scratch with high reliability
• Are an expert in at least one statically-typed language (e.g. Go, Rust, C++), have a strong bias for type-safety, and can decide the best programming language for a task considering trade-offs (velocity, scalability, maintainability)
• Have a strong understanding of computer science fundamentals, algorithms, and databases
• Are experienced in deploying services (docker, kubernetes) to at least one of GCP, AWS, Azure
• Use AI to augment yourself, but you also augment AI (thoroughly review AI-code, catch its bugs, and call-out poor design)
• Are invigorated by high-performing peers and doing high-quality work
• Love technically challenging problems

• Comprehensive Medical/Dental/Vision insurance for you and dependents, including $0 premium plan with company HSA contribution
• 401(k) plan with 4% match
• Catered daily team lunch
• Urban downtown San Mateo office, 5-minute walk from Caltrain and free parking
• Time off as you need it
• Top-quality computers and ergonomic workspace
• Corporate AI subscriptions as much as you need for work

• We seek out the 10% of people who account for 90% of productivity and strive to be a small and talent-dense team.
• No formal performance reviews. If you're here, you're a high-performer.
• Our organization is flat with no middle managers and you will work directly with the founders who all code.
• No empire building – we operate as one team.
• If you see something you can fix efficiently end-to-end, just do it.
• We love being in-person at our San Mateo office 5-days a week for maximum bandwidth communication and enjoying delicious local food together.
• We write blameless post-mortems (incident reports) for any service outages to document and constantly improve reliability.
• We “Feel the AGI” and want to bring it to others to massively improve productivity.
