Senior Embedded Engineer, Connected Devices

About Branch

Branch is shaking up the $46B office products industry to create the best work experience for the 21st century: easy, affordable and adaptable so you can sit down (or stand) and get to work.

Most people spend eight hours a day at their workspace. Our mission is creating accessible and inspiring products to help people and teams feel their best at work, wherever that happens.

We’re based in NYC and Toronto, and backed by the investors behind Quip, Caraway, Eight Sleep and Peloton. Our culture combines strategic clarity with scrappy execution; we think and plan rigorously but ship fast and have fun doing it. We’re looking for entrepreneurial teammates who do the same.

We’re hiring a Senior Embedded Engineer to help us build the next generation of connected products  Connected Devices program is small, ambitious, and moving fast: we’re shipping a new wave of products that bring intelligence and connectivity to the workday, and we need a hands‑on technical leader who can take them from prototype to mass production alongside us.

This is a rare role. You’ll be the day‑to‑day technical counterpart to our Director of Product (Connected Devices), with a world‑class senior hardware architect as your advisor and mentor. The architect operates at the level of design reviews, architectural design and manufacturing builds; you’ll own the work that fills in the gaps: the bring‑up, the bug hunts, the firmware features, the test fixtures, and the integration with our cloud and app teams.

The ambition is for this person to grow into the technical lead for the program, across multiple Connected Devices projects.

• Lead the day‑to‑day firmware development for our connected products, from feature implementation to debugging to release management
• Drive hardware bring‑up on new revisions: power rails, clock validation, peripheral verification, and the unglamorous bench work that proves a board is alive
• Own embedded development across our microcontroller stack, including wireless connectivity and the sensor integration that makes our products intelligent
• Design and own the test fixtures we use in manufacturing; this is critical, infrequently glamorous work that makes or breaks production quality, and you should expect to lead it
• Be the person on‑call, on the factory floor, who makes sure manufacturing goes right the first time
• Work hand‑in‑glove with our external design and manufacturing partners; set the bar for what we accept from them
• Partner with our senior hardware architect on design reviews, firmware verification plans, and manufacturing builds, freeing them to focus on high‑leverage initiatives
• Plan and execute against EVT, DVT and PVT milestones, along with the documentation and process work that makes production‑grade quality possible
• Travel up to 20% of the time, including overseas, to design and manufacturing partners for hands‑on builds and issue resolution
• Work closely with our product, industrial design, app and cloud teams to make sure the hardware, firmware and customer experience all line up
• Use AI tools (including Claude) aggressively to accelerate development, automate repetitive work, and lift the team’s overall velocity

• 3+ years of professional experience as a firmware, embedded or hardware engineer, with at least one shipped consumer or commercial hardware product to your name
• Strong C/C++ skills for embedded development on ARM Cortex‑M class microcontrollers, ideally with hands‑on experience on ESP
  32 (our default platform), Nordic nRF, STM
  32, or similar production‑grade So Cs
• Solid software engineering fundamentals: data structures, design patterns, modular code, and version control with git
• Experience with embedded bus and peripheral protocols (SPI, I2C, UART, GPIO) and the debugging tools that come with them
• Proficient in Python for test automation, manufacturing tooling, and hardware validation scripts
• Experience with wireless protocols (BLE, Wi‑Fi, Thread, Zigbee or similar)
• Familiarity with IOT sensors: IMU, capacitive, load cell, presence, etc.
• Hands‑on hardware experience: comfortable with a soldering iron, a scope, a logic analyzer and a JTAG debugger; able to read a…
