Senior Full Stack Engineer - Task Mining

Celonis is the global leader in Process Intelligence and the pioneer of Process Mining technology. As one of the world’s fastest-growing enterprise SaaS companies, we are changemakers pushing the boundaries of what’s possible. We invest heavily in advanced AI capabilities—specifically our Process Intelligence Graph—to turn data insights into immediate business action. We believe there is a massive opportunity to unlock global productivity and sustainability by placing intelligence at the core of every business process. Join our mission to make processes work for people, companies, and the planet.

The Team

Our team builds Celonis' end-to-end Task Mining solution. Task Mining is the technology that lets businesses capture user interaction data (desktop) so they can analyze how teams actually get work done — and how they can do it even better. We own the full stack behind it: the desktop client, backend services, data-processing pipeline, and Studio frontend applications.

The Role

We're looking for a Senior Full Stack Engineer who's happiest working across the whole stack — from the Studio UI users interact with, through the backend services and APIs, down to the data pipeline — and who has a solid understanding of the algorithmic and AI backend that powers our insights.

You don't need to be the person inventing the ML algorithms, but you should be comfortable working alongside them: integrating AI/ML capabilities into real products, building the UIs that make them usable, exposing them through clean APIs, and reasoning about the data that flows through it all. Our mission is broad and growing: turning raw signals about how people work into structured, actionable insight. We want someone who can help turn these capabilities into polished, end-to-end product experiences.

You'll work primarily in TypeScript/Angular on the frontend and Python & Java on the backend, with SQL across the data layer. You'll set technical direction, raise the engineering bar, and mentor others along the way.

What you'll do

• Build features end-to-end — design and ship user-facing capabilities that span the Studio frontend, backend services, and the data pipeline behind them.
• Craft great UI/UX: build performant, accessible, well-tested Angular applications that make complex Task Mining data and AI-driven insights intuitive to work with.
• Develop robust backend services and APIs (async Python; Java) on a multi-tenant SaaS platform, and the data models behind them.
• Integrate AI and algorithmic capabilities into the product — connect discovery/extraction/insight features to real UIs and workflows, with the right guardrails, feedback, and observability so users can trust the results.
• Work fluently with data: write and understand SQL (and PQL, our Process Query Language), and help shape how data moves through ingestion, processing, and transformation.
• Own delivery end-to-end: lead design, implementation, build, and shipping to customers.
• Provide technical leadership and mentorship — drive design discussions, code reviews, and technical planning to keep standards high and knowledge shared across frontend and backend.

The qualifications you need

• 5+ years of practical software engineering experience building and shipping production applications.
• Strong full-stack ability: proven experience with a modern component-based frontend framework (Angular ideal; React/Vue transferable) in TypeScript, and building robust backend services and APIs.
• Strong backend engineering skills in Python & Java (async services/APIs) and/or comparable languages.
• A solid understanding of algorithms and AI/ML concepts — enough to integrate, reason about, and productize AI-driven features (including LLM-based ones), even if you're not building the models yourself.
• Good grasp of data fundamentals: SQL and query optimization, ETL, and data modeling.
• Experience with containerization (Docker) and CI/CD (e.g. GitHub Actions).
• Quality care: testing, typing, accessibility, and performance.
• Strong communication and collaboration skills (English is a must).

What Celonis can offer you:

• Pioneer Innovation: Work with the global leader in Process Mining and the Process Intelligence Graph to shape the future of AI-driven business operations.
• Ownership from Day 1: Every full-time "Celonaut" is an owner, receiving Restricted Stock Units (RSUs) and merit-based refresh grants.
• Unrivaled Family Support: Benefit from our inclusive parental leave policy—24 weeks of fully paid leave for primary carers and 12 weeks for supporting carers, available from your first day of employment.
• Work-Life Integration: Enjoy Unlimited PTO (in applicable regions) and generous PTO globally, as well as a flexible hybrid work model that balances remote focus with vibrant office collaboration.
• Continuous Growth: Elevate your skills through our 70-20-10 learning framework, mentorship programs, and access to a dedicated learning platform.
• Holistic Well-being: Prioritize your health with subsidized Wellhub memberships, mental health counseling, and dedicated "Wellness Weeks" that prioritize work/life balance.
• Drive Sustainability: Participate in annual Impact Days, where you receive paid time off to volunteer for community and environmental causes with your local office, or virtually.
• Global Inclusion & Belonging: Find community through our Inclusion Think Tank and participate in our annual Inclusion Days, ensuring every voice is heard and valued.
• Value-Driven Impact: Join a mission-led organization where our core values—Live for Customer Value, The Best Team Wins, We Own It, and Earth Is Our Future—drive every decision.
