Senior Firmware / Embedded Engineer - HiQ Mälardalen

About Humans since 1982: We are a pioneering studio based in Stockholm, working at the intersection of design, art, and technology. Our kinetic installations, including A million Times and ClockClock, have found audiences around the world. Among our collectors are institutions such as the Vitra Design Museum, companies including OpenAI, as well as global thought leaders across business and culture. Our work is guided by a simple idea: “Form follows fascination.” Curiosity is where every project begins. While the outcomes often take the form of physical objects, we approach them dramaturgically, arranging anticipation, surprise, and resolution. About the role What you'll do * Redesign and optimize the power architecture to support a large number of synchronized units operating from a shared power system * Strengthen and scale the communication architecture for a multi-node installation * Develop, test, and harden embedded firmware for reliable long-term operation * Diagnose and resolve system-level reliability issues across hardware and software * Prototype, validate, and refine solutions through hands-on testing * Bring the system to a production-ready, reproducible state within the project timeline Who we think you are * You have successfully delivered embedded electronics products from prototype through production * A strong embedded firmware engineer, ideally with C/C++ on platforms such as STM32, ESP32, or similar MCUs * Comfortable with hardware bring-up, debugging, and system integration * A solid understanding of power electronics, motor control, and electromechanical systems * You thrive in independent, senior-level roles and communicate clearly in a remote working environment Nice to have: CAN bus or other industrial communication protocols · EMC, electrical safety, or compliance experience · motion-control systems at scale · embedded Linux. Engagement * Contract / project-based engagement * Flexible working hours over the next ~6 months, with a minimum of 20 hours per week * Open to different setups — for example full-time across ~3 months, or 30–60% across ~6 months * Start date: August–September 2026 * Remote, with a strong preference for on-site time in Stockholm during key development, testing, and integration phases * Opportunity for additional project work beyond the initial engagement What we offer * Ownership of a technically ambitious and highly visible project * Direct collaboration with our technical lead and senior hardware advisor * Flexible working with overlap across European working hours * The opportunity to contribute to internationally recognised design and art projects * A rare working environment at the intersection of engineering, design, and contemporary art We review applications on a rolling basis, with interviews from August. Culture at Humans since 1982 At Humans since 1982, we work in a small but distinctive field where design, art, and engineering meet. Our studio creates collectible pieces that require patience, precision, and a genuine fascination for how things work, unfold and surprise over time. We are a curious and collaborative team. Everyone in the studio is trusted to take ownership of their work, think independently, and contribute ideas beyond their immediate role. At the same time, our projects are collective efforts, built through dialogue, shared curiosity, and a respect for each other’s craft. The studio still operates with an entrepreneurial spirit. We are flexible and move quickly when ideas take shape, but we also recognise that meaningful work takes care and attention. As we continue our journey, every person in the team helps shape not only the work we create, but the culture of the studio.

YOUR MISSION AT VOI We operate one of the world’s largest connected micromobility fleets, with close to 200,000 vehicles across multiple hardware generations, vehicle models and markets – and we will keep scaling significantly in the coming years. As our fleet grows in scale and complexity, firmware reliability, platform architecture, and operational robustness become increasingly critical to the business. Ultimately, your work ensures that every Voi vehicle feels safe, reliable and effortless to use – even after years of real‑world use, rough weather, and everyday wear and tear. We are now looking for a deeply experienced Staff Embedded Engineer to help lead the next generation of our vehicle and IoT platform. In this highly hands-on technical leadership role you will shape the long‑term embedded platform strategy and architecture, and work across teams, suppliers and partners to make sure our vehicles are consistently reliable. You will, among other things: * Translate rider and operator needs into platform‑level design decisions, ensuring our vehicles are intuitive to use, reliable over years in the field and straightforward for local teams to operate and maintain. * Architect and evolve a large‑scale distributed embedded platform spanning vehicle control systems, battery‑powered IoT devices and multi‑MCU/MPU platforms (including Zephyr / Linux‑capable systems). * Develop and scale platforms capable of hosting multiple ML models on‑edge based on computer vision and other sensors. * Drive the evolution of fleet‑wide OTA infrastructure, remote diagnostics and observability for hundreds of thousands of devices across 100+ cities in Europe. * Lead technical discussions and design reviews with internal teams and external hardware suppliers and manufacturing partners. * Improve resilience and recovery mechanisms for remotely deployed systems, including safe rollback strategies and recovery of bricked devices. * Drive improvements in CAN‑based vehicle communication, power systems, GNSS and geofencing in dense urban environments, and sensor reliability, including Bluetooth and NFC user interactions. * Raise the bar for engineering excellence across embedded and firmware engineering, mentoring others, refining CI/CD, testing and release processes, and introducing best‑in‑class development practices. * Champion the strategic and pragmatic adoption of Generative AI tools to increase engineering effectiveness while protecting code quality and minimising technical debt. WHAT YOU NEED TO EMBARK You are a hands-on, senior technical leader who thrives at the intersection of firmware, hardware, connectivity and large‑scale operations. You are confident in navigating high complexity, balancing strategic architectural choices with pragmatic delivery, and you enjoy mentoring others and setting engineering standards. You care about the end‑to‑end experience: from how a rider feels stepping onto a scooter, to how easy it is for our operations teams to keep the fleet safe, available and healthy over time. We believe you will bring: * Extensive experience building and operating embedded / firmware systems in real‑world environments at scale (ideally globally distributed connected device fleets). * Strong skills in embedded C/C++ development and low‑power, real‑time embedded systems. * Deep understanding of firmware architecture, hardware / software integration and distributed IoT systems. * Proven experience debugging complex field issues across firmware, hardware, manufacturing and connectivity layers. * Strong experience with embedded communication protocols such as CAN, SPI, I²C, UART and BLE. It’s a plus if you have experience with: * STM32‑based or other heterogeneous embedded architectures, and modern RTOS platforms such as Zephyr. * Secure boot, TrustZone, TPMs or other embedded security architectures, as well as Embedded Linux systems. * GNSS, geofencing, sensor fusion or other edge‑processing systems, and battery‑powered devices with a focus on power optimisation. * Operating large, globally distributed IoT fleets across varied connectivity environments, including recovering from real‑world operational failures, factory issues or large‑scale fleet incidents. This role is likely a strong match if you have scaled firmware deployments globally, built systems that remain reliable under unreliable real-world conditions, and driven architecture decisions across multiple hardware generations with a focus on long‑term maintainability and operational visibility. Don’t meet every requirement? If you are excited about this role and our mission, and have relevant, transferable skills, we encourage you to apply – even if you don’t check every box. WHY VOI? Working at Voi is more than just a job; our People Promise includes a personal voyage where you will grow as a professional and be a part of a team and culture that builds something meaningful for society. In addition to this you’ll have the opportunity to: * Join Europe’s #1 micromobility operator * Get “skin in the game” through our employee options programme. * Enjoy unlimited free Voi rides and a dog‑friendly office. * Work together with inspiring, motivated and fun colleagues towards a common goal. * Join the micromobility revolution and be a part of creating sustainable cities made for living, free from noise and pollution.
