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.

Role Purpose

As a Software Engineer on the Aircraft team with a firmware focus, you will own delivery of firmware and low-level software running on aircraft hardware. You’ll work close to electronics, sensors, and power systems, taking responsibility for reliability from silicon to system-level behavior.

This role is ideal for an engineer who enjoys embedded systems, hardware bring-up, and deep debugging — and who wants ownership of firmware that directly affects aircraft safety and performance.

Key Responsibilities

Develop low-level code in Embedded C/C++, including drivers, hardware interfaces, and control logic.

Participate in board bring-up, peripheral integration, and hardware validation.

Own firmware lifecycle: development, testing, deployment, and in-field support.

Lead end-to-end delivery of firmware features, from design through rollout and monitoring.

Improve robustness through watchdogs, telemetry, logging, and diagnostics.

Debug complex issues across firmware, hardware, and higher-level aircraft software.

Build and improve firmware testing strategies, including unit tests, integration tests, and hardware-in-the-loop (HIL) validation.

Influence architectural decisions related to hardware-software boundaries.

Help raise standards for firmware quality, safety, and maintainability.

Requirements:
Skills & Education

6+ years experience developing production firmware for embedded systems.

Deep proficiency in Embedded C and/or C++.

Experience with microcontrollers, SoCs, and peripheral interfaces (e.g. SPI, I²C, UART, CAN).

Hands-on experience with board bring-up and hardware-adjacent debugging.

Strong understanding of memory management, interrupts, concurrency, and real-time constraints.

Experience shipping firmware to real devices in operational environments.

Experience in safety-critical domains such as robotics, aviation, automotive, or industrial systems.

Familiarity with FreeRTOS, ESP-IDF and/or STM environments.

Experience with power electronics, battery management systems, or charging hardware.

Exposure to ArduPilot/PX4, ROS/ROS2, or similar robotics platforms.

Python experience for tooling, testing, or automation.

Familiarity with Linux-based embedded systems.
