Job summary

Launchpoint is seeking a backend engineer to own core systems end to end, from design through production. You will work with a very small team, handle high-stakes data, and ensure reliability in a fast-moving environment.

You will apply AI where it matters, set architectural standards, and collaborate directly with customers to decide what gets built next. This is high-responsibility work with meaningful impact.

Qualifications

• 2–5 years building and running production backend systems.
• Exceptional TypeScript. We write TypeScript across the stack, with React Native on mobile.
• Depth in data modeling and in making systems fast and correct at scale.
• A record of taking hard, ambiguous problems to production with very little oversight.
• High standards and high speed at the same time. You don't trade one for the other.
• Product judgment. You care whether what you shipped moved a number for a customer.

Responsibilities

• Own core backend systems end to end, from the first design through production and everything that happens after.
• Build for volume that grows every month, in a domain where a wrong number costs someone real money.
• Solve problems nobody has written the answer to: messy real-world data, people actively trying to game the system, and infrastructure that has to hold under load.
• Apply AI where it changes what a small team is capable of.
• Set the technical bar for architecture, code quality, and how fast the team ships.
• Work directly with customers and decide what gets built, not just how.
