Senior Fullstack Engineer - Automations

Personio's intelligent HR platform helps small and medium-sized organizations unlock the power of people by making complicated, time-consuming tasks simple and efficient. Our growing team of 1,800+ Personios across Europe and the US are building user-friendly products that delight our 14,000+ customers and their 1.5 million employees. Ready to make an impact from day one?

The Role: We’re looking for a Senior Fullstack Engineer to join one of several teams within the Workflow Automations product area. The Automations product enables mid-sized and large businesses to operate at scale. Our product teams enable employees to set up and automate complex business processes via intuitive experiences. We build and operate platforms and services at scale that enable customers to get their HR work completed efficiently. We also operate the Document Management platform, one of the most used features within Personio.

What You'll Do:

• Develop High-Impact Solutions – Design and build scalable, efficient backend/frontend systems using Kotlin on the backend and React on the frontend.
• Full-Stack Contributions – The role is sometimes more frontend and sometimes more backend-heavy so you will regularly work between these areas.
• Cross-Team Collaboration – Partner with frontend and backend engineers, product managers, and other teams to align on priorities and deliver end-to-end solutions.
• Improve System Performance – Optimize API performance, database queries, and reduce frontend latency for high-traffic web solutions.
• Operational Excellence – Participate in on-call responsibilities and build alerts and monitoring to ensure services remain online 24/7. Proactively enhance engineering processes and incident management.

What We’re Looking For:

• Product Engineering sensibilities – You enjoy solving customer problems through your work. This means you provide proactive feedback to your EM/PM, make fixes without being asked to do so, and keep the customer in mind as you build products.
• Growth Mindset – You are eager to grow with each project and seek to learn from others. You’re also open and interested in mentoring others.
• Strong fullstack feature development abilities – You enjoy jumping between the frontend and the backend and can take features from product spec to completion. You do whatever it takes to get there and you’re not afraid to tackle new challenges.
• Experience at scale with the ability to stay scrappy – You have worked on high-traffic web applications and large codebases. Nevertheless, you remain scrappy in order to maximize velocity.
• Strong design/architecture skills – You have a solid understanding of API design, architecture, and distributed systems.
• Excellent collaboration and communication skills – Clear, transparent and regular communication is essential for the team and its stakeholders.
• Comfort working with other teams – You are at ease working in a cross-functional team environment, collaborating with product managers and engineers on other teams.

If you do not have all the qualifications for this role, we still encourage you to apply. We believe in creating an environment where you can learn and grow as an engineer. With a positive and high accountability attitude, we’re confident you’ll fit in well.
