Job description

Full Stack Security Software Engineer

WindBorne Systems is supercharging weather forecasts with a unique proprietary data source: a global constellation of next‑generation smart weather balloons targeting the most critical atmospheric data. We design, manufacture, and operate our own balloons, using the data they collect to generate otherwise unattainable weather intelligence.

We're hiring a Senior Full‑Stack / Security Software Engineer to own core, security‑forward infrastructure. You will build robust systems that can handle business‑critical needs around data delivery, flight tracking, and other operational demands. You must be fluent with government‑compliant requirements as you will be the core owner ensuring internal systems can serve our growing contractual obligations.

We are a small team handling all the software that keeps our entire constellation in the air. Development speed and robustness/security/stability are not mutually exclusive; we value pragmatic decisions, high autonomy, low egos, and a willingness to get your hands muddy in the dirt.

Responsibilities

Data pipeline integrity — Balloon observations flow from satellite downlinks through processing workers into customer‑facing APIs. Ensuring this pipeline is reliable, tamper‑evident, and correctly permissioned is as important as making it fast.
Architecting core infrastructure to support projects requiring clearance.

Skills and Qualifications

You'd be a good fit if you:

Have built and shipped full‑stack applications — fluency and comfort working with Ruby on Rails, Postgres, or the ability to quickly and pragmatically learn on the job.
You’ve been responsible for 24/7 uptime systems. You can implement pragmatic best practices forged from real‑world, experienced pain of handling such a system.
Have worked in environments where data sensitivity was a real constraint — healthcare, defense, fintech, infrastructure, or similar.
Have experience with role‑based access control, secrets management, or data classification in production systems.
Want to work in‑person in Redwood Shores, CA with a small team where your decisions have immediate, visible impact.

Parts of this role may involve work on U.S. government contracts or export‑controlled systems. This can require eligibility for a U.S. security clearance or to be a U.S. citizen.
