Senior Embedded Engineer

In shortIf you're a Senior Embedded C engineer who gets why a misbehaving radio at 2 AM is both annoyingand the best puzzle of your week, we'd love to talk. You'd be joining us on a freelance, time &material basis: you're paid for the hours you actually work on real client projects. We're ready tostart right away, at full capacity. The first three months are about getting to know each other: if itturns out we work well together, we'd love to bring you into our core team with a fixed monthlysalary, paid time off, and the whole benefits package. Not a promise, a real possibility we activelyroot for.Why intent (https://himalayas.app/companies/intent)?We've been designing and co-creating connected devices since 2008. Wearables, smart audio,health-tech hardware for clients like Oura, BOSE, and Neurable, backed by investors like a16z andFounders Fund. We're 60+ people, fully remote, and we've been AI-native since before LinkedIninfluencers discovered the term. We use AI every day, in actual work, not just in company decks. Ifyour C code has ever made an antenna, a sensor, or a medical-grade device behave itself, youalready get why we love what we do.Who this role is NOT forIf you like being handed a spec, a ticket, and a "wake me when it's done", we're probably not yourpeople. Embedded at intent (https://himalayas.app/companies/intent) means chasing edge cases across silicon, stacks, and radios, sometimesin the same afternoon. We're looking for engineers who ask "why" before "how", who read adatasheet and then actually question it, and who know that "it works on my bench" is the beginningof the conversation, not the end. We're AI-native and we expect you to treat AI as a daily multiplier(digging through vendor docs, drafting test harnesses, reasoning about tricky timing issues), not as agimmick. On freelance: we're not expecting you to rewrite our toolchain in week one. What we doexpect is ownership of what you touch, straight talk when things get complicated, and actualcuriosity about the device on the end of your JTAG.What you'll doBuild and maintain embedded firmware in C for STM32-based connected devices Work inside the Modus SDK and the broader Cypress/Infineon ecosystem to make hardware do what the spec says, and a few things it didn'tIntegrate and tune FreeRTOS: tasks, priorities, queues, interrupts, the whole discipline of not breaking real-time behaviorTackle multi-radio architectures in practice: BLE and Wi-Fi coexistence, arbitration, throughput versus power trade-offs• Collaborate closely with hardware, mobile, QA, and the client's engineering team on cross-functional problemsDebug the unglamorous stuff: logic analyzer, scope, sniffer, logs that don't want to exist Contribute to architecture decisions, code reviews, and knowledge-sharing inside the Firmware & Hardware chapterUse AI tools as part of your daily workflow, not as a party trick How we workFully remote. We have an office in Warsaw. The team operates between 10:00 and 18:00 CET, and that's when most meetings happen.Depending on the project, occasional evening calls with US-based clients (up to ~20:00) may happen,always scheduled in advance, never a surprise. You'll be part of the Firmware & Hardware chapterfor knowledge-sharing, and simultaneously on a project squad led by a PM for day-to-day delivery.What you'll get110-190 PLN/h net B2B, depending on your experience Truly flexible hours (most of the team works 10-18 CET, but you organize your day) • Fully remote (all Europe)Access to our internal knowledge-sharing: tech talks, experiments, side projects No sugarcoating: during the freelance period there's no paid leave or medical benefits. Those comewith the permanent contract, and we're transparent about that upfront.Your first weeksWe don't throw you into the deep end on day one. New engineers go through a structured ramp-upperiod before landing on target projects: you'll work alongside the team, get paired with a technicalbuddy, and tackle progressively bigger tasks so both sides can see how the collaboration feels.Feedback comes early and often, no one waits three months to tell you something isn't working. Webelieve in fast, honest signals: if it's great, you'll know. If something needs adjusting, you'll hearabout it while there's still time to adjust.Recruitment processThe entire process is in English. All interviews are recorded for internal evaluation purposes.Application with a few screening questionsHR call (~45 min, casual)Technical meeting (~90 min, with the technical team)Final feedback within a few days.RequirementsWhat we're looking for5+ years of hands-on embedded C development on ARM Cortex-M platforms Strong, proven STM32 experience (not "I ran one tutorial") Real work with the Modus SDK, or at the very least solid time inside the Cypress/Infineon ecosystemFreeRTOS: you know where the footguns are, and you don't find them by accident Proven experience with multi-radio architectures, especially BLE and Wi-Fi coexistence: ti
