Responsibilities
Build and own core product features: Backend systems, APIs, voice infrastructure, wherever the product needs you
Code ships daily and goes live for Fortune 500 clients
Work on things most engineers never touch: telephony systems, real-time voice processing, and integrations with legacy financial infrastructure
95%+ of your time will be coding and building
We're looking for engineers who can own one of these areas: the orchestration layer that coordinates our voice AI systems, infrastructure scaling and low-level performance, security as a generalist building for Fortune 500 financial institutions, or product engineering close to users finding high-leverage wins
Know what it feels like when things are working: real customers, real revenue, a product people actually need
You also know the chaos, the pace, the things that break at the worst possible time
You've seen both sides and you want to do it again with a team that's already found traction
Four engineers. Everyone ships to production
We do dailies. We groom tickets. But we keep process light and in service of the work, not the other way around
We'd rather spend time building than talking about building
We care about doing great work. Not just shipping, but shipping something you're proud of
Clean abstractions. Systems that don't page you at 3am. Code you wouldn't be embarrassed to open-source
We build things that last because we're the ones maintaining them
Ownership here is real. You won't be handed tasks from a backlog
You'll see what needs to happen and do it. That's how a small team ships to Fortune 500 customers
We hire people whose judgment we trust, then get out of their way. No passengers
