Hire embedded engineers

Embedded software is unforgiving in a way web software is not. A bug in a web app gets patched the same afternoon. A bug in firmware ships inside a physical product, drains batteries in the field, bricks devices during an update, or forces a hardware revision that costs months. Plenty of developers write C. Far fewer can bring up a board from a datasheet, write a driver that behaves under interrupt load, and debug a fault with a logic analyzer instead of a print statement. turnkey.dev vets for the second group.

What an embedded engineer does for you

A strong embedded hire will:

• Bring up your hardware: board bring up from schematics and datasheets, bootloaders, peripheral configuration, and a build system the rest of the team can actually use.
• Write firmware that respects the constraints. Tight memory, limited power, and real time deadlines, handled with an RTOS like FreeRTOS or Zephyr or a clean bare metal loop, chosen for the product rather than habit.
• Own the drivers and protocols: I2C, SPI, and UART peripherals, sensor integration, and the vendor SDK quirks that consume weeks when nobody on the team has seen them before.
• Connect the device safely: BLE and MQTT connectivity, provisioning, and firmware update mechanisms that recover from a failed flash instead of bricking units in the field.
• Debug at the metal. JTAG and SWD debugging, logic analyzers, profiling, and the discipline to find a hard fault or a race condition rather than paper over it.

When to hire an embedded engineer

The common triggers: you have a hardware product and the firmware is behind the electronics, your prototype works on the bench but fails in the field, your one firmware developer left and nobody else can touch the codebase, or you are adding connectivity to a device that was never designed for it. Teams also come to us when a consumer IoT product needs over the air updates done properly before scaling production. If your need is mostly cloud side, ingesting and processing device data, the AWS hub below is often the better fit, and many projects need both.

Hiring embedded is not like hiring web

Expect the process to differ from a web hire in a few concrete ways:

• The pool is far smaller. Embedded engineers are outnumbered by web developers many times over, and the strong ones rarely stay on the market long, so a role that sits open for months is common when you search cold.
• You cannot judge the work from a portfolio link. Firmware ships inside devices and sits under NDA, so vetting has to probe how a candidate thinks about constraints, failure, and debugging rather than browse a GitHub profile.
• Mistakes cost more. A web bug is a hotfix. A firmware bug can mean a hardware revision, a field recall, or thousands of bricked units, so weight your evaluation toward carefulness and debugging depth over raw speed.
• The interview should live near the hardware. Algorithm puzzles predict little here. Asking a candidate to reason through an intermittent fault, a memory corruption, or a misbehaving peripheral tells you far more.
• Ramp-up is real. Even a strong engineer needs time with your board, your toolchain, and your vendor SDK. Continuity matters more than in web work, and losing your only firmware person hurts more.

How turnkey.dev vetting works

Every engineer goes through a screen on fundamentals (C and C++, memory management, concurrency, and how hardware actually behaves), a practical exercise built around a realistic firmware and debugging scenario, and a review of devices they have shipped, including the constraints they worked under and what broke after launch. Familiarity with a vendor toolchain is noted, but we vet on shipped hardware, because embedded skill only shows up on real devices. We reject far more than we accept.

Seniority, and what each level is for

Most companies coming to us need one senior engineer who can own the firmware, with a principal brought in briefly for decisions like RTOS selection, an update architecture, or a certification push.

Senior signals to look for

• They read datasheets and errata sheets by default and can tell you about a silicon bug that cost them a week.
• They reason about interrupt latency, priority inversion, and what is safe to do inside an ISR without reaching for a reference.
• They prefer static allocation and can explain their heap policy on a constrained target.
• They design updates defensively: A/B partitions or a fallback image, watchdogs, brownout handling, and a clear answer for what happens when power dies mid-flash.
• They treat power as a budget, measuring sleep currents and wake time rather than guessing.
• Handed an intermittent bug, they reach for a logic analyzer or a scope and narrow it down methodically instead of adding prints and hoping.

A weak candidate with the same resume talks fluently about the vendor IDE and goes quiet when you ask what broke in the field and how they traced it.

What it costs and how fast

Vetted embedded engineers typically bill in the $70 to $140 per hour range, with RTOS, driver, and safety specialists at the top. Rates move with seniority and region here as everywhere, and deep hardware specialization pushes them up faster than it does in web work. Compared against the cost of a delayed production run or a field recall, a strong firmware hire is one of the cheaper insurance policies in hardware. You will see the rate before committing, and requesting a shortlist is free. Expect a shortlist in 2 to 5 days.

Start with a request, not a contract

Tell us the hardware (the microcontroller family, the peripherals, the connectivity), the state of the firmware, and the goal, whether that is board bring up, stabilizing an existing codebase, or shipping a connected product. We come back with a short list of vetted engineers who fit, including rate and availability. You interview, run a paid trial if you want, and only then decide. If the fit is wrong in the first two weeks, we re-match at no cost.
