Your Mission
You operate as a trusted adversary within our systems identifying, exploiting, and helping eliminate the risks that matter most. You don’t just find vulnerabilities; you shape how we think about security at a product and platform level.
You’ll embed offensive thinking across the SDLC, partnering with engineering, product, and DevOps to challenge designs, raise the bar, and ensure we’re secure by default, not by accident.
If you’re the kind of person who sees an attack path where others see “low risk,” and you know how to turn that into real change, you’ll feel right at home.
What you'll do
- Lead sophisticated, end-to-end penetration tests across complex systems; uncovering deep, chained vulnerabilities others miss
- Design and demonstrate impactful exploit scenarios that drive prioritisation at both engineering and leadership levels
- Own offensive security engagements from scoping through remediation validation, acting as the technical authority
- Influence architecture through threat modeling and design review; shifting security left and preventing classes of vulnerabilities
- Build and evolve offensive tooling, methodologies, and playbooks to scale security testing across teams
Who you are
- 5+ years in offensive security with a proven track record of finding high-impact, non-trivial vulnerabilities in real-world systems
- Strong depth in application and product security, with the ability to think across layers (app, API, infra, auth, logic)
- Recognised for your hands-on expertise; whether through certifications (OSCP, OSWE, GPEN) or demonstrated offensive work
- Able to influence without authority; translating complex attack paths into clear, actionable risk for diverse stakeholders
- Naturally curious and adversarial; you think in attack chains, not isolated bugs, and push until you find what really matters
What’s in it for you
- Flexibility to work where you thrive – Enjoy the freedom of our Hybrid working model, combining onsite collaboration and remote work, with an additional 25 days per year to work from a city or country of your choice.
- Reward for your impact – Receive a competitive total compensation package aligned with Bitpanda’s pay-for-impact policy, including participation in our stock option plan.
- Support for your mental wellbeing – Access confidential coaching, counselling, and mental health resources whenever you need them through OpenUP.
- Time to recharge – Take extra time off to rest, reset, and recharge, with 3 additional days off in 2026 to prioritise your wellbeing.
- Continuous learning and growth – Grow your skills and stay ahead in your career with unlimited access to Udemy’s library of online courses at your own pace.
- Exclusive perks and rewards – Enjoy discounts, rewards, and perks from partners worldwide across lifestyle, wellness, tech, and travel.
- Support during life milestones – Take advantage of our additional 8 weeks of gender-neutral new parent leave to welcome and bond with your new addition to the family.
- Fuel and focus on-site – Pandas in Vienna, Bucharest, Barcelona, and Berlin can enjoy free onsite dining, with freshly prepared lunches and snacks to keep you fueled and focused all day long.
- Recognition for your contributions – Celebrate milestones and achievements with recognition and rewards for your Tenure at Bitpanda.
- Show your Bitpanda pride – Access exclusive Bitpanda-branded merchandise and gear to represent.
- Connect and celebrate with your team – Join unforgettable company events, from our Winter Party in Vienna to gatherings worldwide, fostering fun, connection, and celebration
.…and even more location-specific benefits designed to make life at Bitpanda even more rewarding wherever you are.
Above all, you will have the opportunity to learn and grow as part of Bitpanda’s incredible journey towards being Europe’s future #1 investment platform.
Bitpanda is committed to fostering a fair and equal environment based on trust and mutual respect. We believe that a diverse and inclusive workplace is paramount to our success and we are committed to building a team that represents a wide variety of backgrounds, perspectives, and skills.
