The Position

We're assembling a small founding team to build something genuinely hard: high-throughput services that inspect live traffic, terminate and analyze TLS in the data path, and hold near-zero latency while doing it. This is real systems engineering — streaming, distributed, latency-obsessed — not another CRUD app behind a form.

You won't be starting cold. You inherit real infrastructure and real users, which means what you build reaches production in weeks, not years. The work is high-leverage from day one, and there's nowhere to hide — in the best way.

AI-native. Non-negotiable. You leverage AI to operate as a 10x engineer — demonstrable AI proficiency is a hard requirement, not a nice-to-have.

What You'll Own

You take a capability from a rough idea all the way to production, and then you keep it alive and healthy there — meeting its latency and reliability targets, instrumented well enough to prove it, and hardened to survive real load and real failure. You own the outcome, not the ticket. You'll lead a functional area end to end: set its technical direction, make the calls that matter, and pull other engineers along with you.

Who You Are

• You see what needs to exist and you go build it — you spot the gap, scope it yourself, and start, instead of waiting for someone to hand you a task or a spec.

• You lead by taking the hardest, least-defined part of the problem and making it work, and others follow because your judgment and output earn it — not because of a title.

• You own the entire arc — design, build, ship, operate — and you treat what happens in production as your responsibility, making sure the system behaves exactly within the parameters it's supposed to, not just that it passed in staging.

• When you hit the edge of what you know — a protocol you've never touched, a failure mode you've never seen — curiosity and sheer grit carry you across it faster than most people expect.

• "Good enough" makes you uncomfortable; you hold a high bar for yourself and ship work you're genuinely proud to put your name on.

What You Bring

• Proven, demonstrable proficiency using AI as a force multiplier — you already operate as a 10x engineer, orchestrating AI tools and agents to design, build, and ship far beyond what you could alone, while keeping the judgment to know what "correct" actually looks like.

• 5–7+ years building and operating production services and front ends, with real experience owning something end to end and carrying the weight of it once it's in front of real users.

• Hands-on experience with TLS / MITM inspection and the security-sensitive edge cases that come with sitting in the middle of live traffic.

• A real track record of taming latency in streaming and distributed systems — you've chased down p99 tail latency and know that "fast on my machine" means nothing until it's fast in production, under load, with observability to back it up.

• Strong command of a modern backend language (Go, Rust, or TypeScript/Node) and React/TypeScript on the front end, with a deep working grasp of HTTP, TLS, gRPC/REST, and async/streaming I/O.
