Full Stack Engineer (all genders)

revel8

OUR MISSION We're on a mission to create 10 million human firewalls! At revel8, we redefine cybersecurity training with hyper-realistic simulations that reflect today's evolving attack landscape. Our innovative platform combines AI-driven multi-channel attacks with gamified, real-time learning to build resilience where it matters most: the people. YOUR MISSION As a (Senior) Software Engineer, you'll take full ownership of the features you build, the technical decisions behind them, and the overall quality of what we ship. You'll work across the full stack on a platform that's scaling fast in a genuinely complex domain. You'll help shape what gets built and how, and have real influence on the engineering culture as we grow. How your day-to-day will look like: * End-to-End Feature Ownership: You drive features through the full development lifecycle from scoping, building, shipping, and iterating until they're truly done. * Architecture Input: You contribute actively to technical design discussions, propose solutions to structural challenges, and help the team make well-reasoned decisions about how we evolve the platform. * Cross-functional Collaboration: You work directly with Product and occasionally with customers to understand problems deeply and design solutions that actually fit the need. * Code Quality & Review: You set a high bar in code reviews, catch issues early, and help maintain a codebase the whole team is proud of. * Informal Mentoring: You support junior engineers through pairing, feedback, and sharing context. You enjoy helping others level up. * Platform Reliability: You take ownership of operational concerns like monitoring, debugging, and improving the stability and performance of systems you've built. IS IT YOU WE ARE LOOKING FOR? You... * Bring 3–5 years of professional experience in software engineering, with a strong track record of shipping features in a backend-heavy environment. * Are proficient in Java and Spring Boot, and comfortable working across the full stack including React and SQL. * Have solid fundamentals in system design. You know how to think about scalability, data modelling, and service boundaries. * Thrive in a cross-functional environment and communicate clearly with non-engineers about technical trade-offs and timelines. * Are comfortable with ambiguity and able to break down complex problems independently, without waiting to be told exactly what to do. * Enjoy working in a small, high-ownership team at an early-stage company where your decisions have real and immediate impact. WHY REVEL8? * Our revelutionary Energy: Join a highly motivated team that values innovation and dedication, while always making space to enjoy the journey and celebrate our successes together. * Mission-Driven Impact: Contribute to a meaningful mission of building human resilience against cyber threats. * Shape the foundation: Join at a critical inflection point and directly influence the architecture of a platform that's growing fast and solving a real-world problem. * A modern tech stack and low tech debt - your decisions matter from day one. * New Munich Hub: Be part of our new chapter! We just moved our headquarters to Munich and prioritize the energy of in-person collaboration in our brand new office as we scale our team - unlimited coffee, table football and good vibes included. * Shared Success: At revel8, all team members are included in our ESOP program, ensuring everyone shares in the success we build together. * Your Daily Balance: With a subsidised EGYM Wellpass you can get access thousands of gyms, studios, and swimming pools across Germany.

This position sits close to the embedded world, but it isn't traditional microcontroller firmware work. You'll own the operating system foundation and platform layer of our IoT devices - building and evolving our next-generation embedded Linux image - and develop the Python application layer that runs on top of it, inside our dockerized main application. You'll work down at the OS and hardware boundary while shipping features up in the application layer. Typical areas include: * Designing and maintaining our Yocto-based Linux distribution for ARM devices with limited compute * Security on device, inter-process communication, networking, scheduling, observation * Over-the-air (OTA) updates for both the OS and applications * Integrating peripherals - watchdog, modem, AI accelerator - and improving their observability * Bridging the system layer and the application layer through Python and Bash The work spans from driver- and kernel-level integration in C/C++, to adapting our Linux distribution with Yocto to the underlying hardware layer, to debugging system-level failures such as memory leaks, up to writing the Python software that turns hardware capabilities into product features. You will be expected to pass a live coding interview for this role. WHAT TO EXPECT * Embedded Linux Platform: Design, build, and continuously evolve the next generation of our Yocto-based Linux distribution for ARM-powered IoT devices * Application Development: Develop Python-based software that brings hardware capabilities to life and improves the reliability and performance of our products * System Integration: Work across the full stack—from kernel and driver integration to application development—connecting hardware, operating system, and product features * Device Reliability: Build secure, observable, and resilient systems, including OTA updates, networking, process communication, scheduling, and device monitoring * Debugging & Troubleshooting: Analyze and resolve complex issues across the platform, including kernel, drivers, networking, memory management, and application software * Ownership: Take end-to-end responsibility for your solutions, proactively improve our platform, and help shape engineering best practices INSPIRE US BY * Embedded Linux Expertise: Several years of experience developing Embedded Linux systems and confidence working with Linux internals, GNU tools, and Bash * Engineering Mindset: Degree in Computer Science, Electrical Engineering, Physics, or equivalent practical experience * Yocto Experience: Proven experience building, customizing, and maintaining Linux images using Yocto * Systems Programming: Strong programming skills in at least one systems language such as C, C++, Rust, Go, or Java * Python Development: Experience developing Python applications or a strong motivation to make Python your primary development language * Low-Level Debugging: Hands-on experience with debugging tools such as GDB, tcpdump, Valgrind, UART, and JTAG, including troubleshooting memory leaks and system-level issues * Operating System Knowledge: Solid understanding of Linux internals, bootloaders, systemd, drivers, kernel concepts, networking, and Docker * Language Skills: Fluent English (C1) EXTRA POINTS FOR * Experience operating large-scale IoT fleets * Knowledge of industrial hardware, cameras, AI accelerators, modems, or network devices * Experience with computer vision, edge AI, or machine learning * Familiarity with MQTT and Protocol Buffers (ProtoBuf) WHAT WE OFFER * Flexibility & Responsibility: Your workday, your performance – Our hybrid model empowers you to focus from home, get fresh perspectives during workation, and connect in person during our Anchor Days (Tuesday to Thursday) * Tailored Mobility: Full speed ahead – Whether it’s sustainable bike leasing or a public transport subsidy, we keep you flexible and on the move * Measurable goals: Our agile methods allow you to directly measure your impact on our product and company success * Team Culture & Networking: Real connections – also beyond the day-to-day.
