Hey HN! Air Space Intelligence (https://www.airspace-intelligence.com) is hiring in Boston. We're a frontier AI and product company for critical industries and defense, backed by a16z.

Last week, the FAA awarded us a 12-year, $875M contract to build FMDS and SMART - the flow-management and airspace optimization systems that will become the technological backbone of the FAA's Air Traffic Control. What we ship in the next two years will define how this country moves through the sky for the next fifty.

At the core is one of the largest real-time optimization problems in the world: how do you safely sequence ~40,000 flights/day while routing around weather, military airspace, equipment outages, and constant real-world churn? The system has to be right every time, and reliable at scale.

More here: https://www.faa.gov/newsroom/modern-skies-trumps-transportat...

We're hiring across Backend, Infrastructure, and Frontend (ICs and Tech Leads).

One of our roles (with a small puzzle at the bottom that routes to my email): https://www.airspace-intelligence.com/careers/role?=1336c828... — include "HackerNews" in the subject so I can prioritize.

Robotics startup (STEALTH + YC S26) | Principal Mechanical + Firmware + SWE | SF Bay Area | ONSITE | $200–250k + 1–2% equity + benefits

We are a new robotics company based in Palo Alto, California, building wearable robotic devices that improve the endurance of humans on foot.

Our first product is a lightweight, bilateral hip product that reduces the physical cost of carrying heavy loads over distance, allowing personnel to move farther, carry more, and arrive at the objective less fatigued and more effective. The company is early but already operating in the field, with a direct feedback loop in the most demanding conditions imaginable.

We are backed by Y Combinator and a group of leading deep-technology investors.

We've recently moved to the Bay area to grow the team, and are hiring three lead engineers who will own product/ their domains, and have full authority with no inherited design decisions and no one between them and the problem. What you build will be worn in weeks by real users:

- Mechanical: structures, joints, actuator integration, ruggedness

- Firmware: real-time motor control, sensor fusion, embedded systems

- Software: device-to-cloud telemetry, test infrastructure, user apps

Shoot me (founder) a text (+1 857-327-3414) and I'll tell you exactly what we're building :)

Ecosmic | Senior DevOps Engineer | Remote (Italy) | €50,000–€60,000

Ecosmic is on a mission to reduce threat exposure in space by building software for Space Situational Awareness. To achieve this, we built a team of flight dynamics engineers and computer scientists to build & package in-house algorithms into easy-to-use, reliable, and secure products. As an example, our platform recently allowed us to identify a series of close approaches in GEO involving Russia's Luch/Olymp-2 and a Western telecommunications satellite, possibly attributed to SIGINT activity.

We're hiring a Senior DevOps Engineer (strong mid-level candidates are welcome too!) to aid the effort of unlocking on-premises deployments of our algorithms with Kubernetes, and to contribute to the evolution of our platform.

Our stack includes Python for backend services and high-level algorithm tooling, C++ for performance-critical components, AWS for cloud infrastructure, and Terraform for IaC. We currently use managed serverless services, and we’re beginning a gradual migration from C++ to Rust for its reliability guarantees.

You’d join a team of three software engineers who love working in such a fantastic domain. I currently take care of most of the infrastructure work with the team, and we’re looking for someone who can help us tackle this new challenge.
