(Senior) Software Engineer (all genders)

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.

• 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 Office: We thrive on an office-first culture and moved our whole team from Berlin to Munich in February - unlimited coffee, table soccer 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.

About us

revel8 is building the next generation of cybersecurity awareness for the age of GenAI. We help organizations protect themselves against modern social engineering attacks by turning their employees into an active line of defense.

It's been a fast ride so far: Founded in August 2024 by Tom and Julius, we moved to the Merantix Campus in Berlin and welcomed Robert as our CTO and co-founder shortly after. We landed our first enterprise customer in March 2025, raised our €5.1M seed round in September 2025, and moved the whole team back to Munich in February 2026. Today, we are around 40 revels working side by side in our new office every day.

Early days. Big mission. Come build it with us!
