Member of Technical Staff
Early-career-to-mid full-stack engineer on a small team building AI-powered browser automation for healthcare workflows. Day to day: improve automation-building agents, scale worker orchestration and job queues on AWS, and ship APIs, SDKs, and observability tooling across the stack.
Founding Engineer
Founding engineer at Clera, an early-stage San Francisco startup building a cloud-first platform for orchestrating coding agents. You'll build the orchestration engine, run agent workloads across cloud, bare-metal, and customer infrastructure, and develop desktop, web, and mobile interfaces alongside the founders.
Software Integration Engineer - HIL
A hands-on role on Stoke Space's software integration team, owning the software configuration and lifecycle of HIL rigs and ground support equipment for the Nova reusable rocket. Day to day the engineer writes Rust/Linux tooling, automates ground networks and test hardware, and physically builds and troubleshoots racks, checkout carts, and avionics integration.
Vehicle Software Engineer – Rust Controls
Builds a Rust-based automation framework that lets Stoke Space teams compose vehicle and ground control behavior for benchtop checkouts, engine hotfires, and flight of the Nova reusable rocket. Day-to-day work spans Rust and Python, distributed software-hardware control abstractions, guardrails, tests, and hardware test support.
Software Engineer, AI Developer Platform
Backend engineer at Mirage (an AI video company) owning the path from commit to production: rebuilding CI/CD, safe deployments, agent sandbox environments, AI code review, and security pipelines to handle AI-agent-scale code volume, while shipping features across its AI video products and developer platform. In-person at NYC HQ.
