About Manna

At Manna, we’re changing how the world receives things — by taking delivery to the skies.

Our mission is simple but ambitious: to make high-speed suburban delivery affordable, green, and safe. We design and build our own aviation-grade drones that deliver food, coffee, groceries, and more — directly from local stores and vendors to people’s doors in just a few minutes.

We’re a team that Drive with Impact, are Safety Focused, and knows that the best ideas come from Team Players who show up as their Authentic Selves. We move fast, we are passionate about what we do, and we’re always pushing a growth mindset to be better — in everything we do.

If you want to build world-changing technology with real-world impact (and have a bit of fun while doing it), you’ll love it here.

Welcome to Manna — where we deliver the future.

Team mission

The Aircraft team is responsible for the software and firmware that runs onboard Manna aircraft and supporting hardware — including flight computers, sensors, chargers, batteries, and other critical systems. This software directly affects flight safety, aircraft reliability, and fleet scalability. We work close to hardware, real operations, and real aircraft. Engineering decisions here have immediate real-world impact.

The role

As an Embedded Engineer- Aircraft on the Aircraft team, you will contribute to delivery of core subsystems within the onboard aircraft platform. You’ll design, build, and maintain embedded and onboard software, mentor other engineers, and raise the bar on reliability and safety.

This role is ideal for an experienced engineer who enjoys working close to hardware, taking end-to-end ownership, and solving hard systems problems in a safety-critical environment.

What you’ll do

• Design and build embedded and onboard software components running on aircraft and supporting hardware.
• Deliver complex features: design, implementation, testing, rollout, and monitoring.
• Work primarily in C++ / Embedded C/C++, with Python used for tooling, testing, and support systems.
• Collaborate closely with hardware, airspace, QA, and manufacturing teams to deliver safe, reliable systems.
• Participate in aircraft bring-up, debugging, and in-field issue resolution.
• Design software with failure modes, fault tolerance, and observability in mind.
• Investigate and resolve complex aircraft and hardware-adjacent issues.
• Contribute to architectural discussions and influence technical direction of the Aircraft platform.
