About Happeo

Happeo is a Series B startup revolutionizing how organizations collaborate and communicate through our unified social intranet platform. We combine collaboration tools, knowledge sharing, and internal communications into one seamless solution that helps teams connect and stay aligned.

We pride ourselves on our dynamic, collaborative culture that emphasizes delivering high-quality solutions while fostering professional development. No bureaucracy, just smart people building things that matter.

About the Role

You’ll be working on the Knowledge Engine team to build Happeo’s proprietary technology for intranet information management. The platform helps organizations discover what they need, identify gaps or outdated content, and streamline creation and sharing workflows. We’re launching into Open Beta with some exciting challenges around content intelligence and search.

Our Stack

React/React Native frontends, Python/Node.js/Java backends, running on GCP (App Engine, Cloud Run, Kubernetes, Cloud SQL, Firestore, VertexAI).

What You’ll Do

Ship AI solutions from zero to production with minimal oversight. You’ll have significant autonomy to define technical approaches, make architectural decisions, and drive product direction. This isn’t a role where you’ll be given detailed specs – you’ll need to form opinions about what to build, how to build it, and why it matters.

Your Typical Day

• Own entire features from ideation to production deployment
• Make technical decisions independently while collaborating with cross-functional teams
• Identify product opportunities that others might miss and champion them
• Optimize performance and scalability based on your assessment of priorities
• Stay current with AI/ML developments and decide which ones are worth adopting

What We’re Looking For

• Strong proficiency in Python + AI/ML libraries
• Experience shipping production AI systems, especially with LLMs/NLP
• Backend experience (Node.js or Java preferred)
• Cloud platform experience (AWS, GCP, or Azure)
• Self-directed problem solver who thrives in unstructured environments
• Comfortable making decisions with incomplete information and defending your choices
• Product sense: you care about building things users actually want
• Located in or willing to relocate to Helsinki, Finland or Cluj, Romania

Nice-to-haves

• RAG, vector databases, graph databases
• Docker/Kubernetes
• Data engineering and ETL pipelines
• DevOps/CICD experience

Perks and benefits

• A competitive salary and equity plan
• Flexible office setup with remote and hybrid working possibilities
• Full 5-weeks holiday policy from day one
• Comprehensive benefits, including healthcare, lunch, and phone subscription
• Top-tier work equipment you need to succeed
• A strong karaoke culture at practically every company event!

If needed, we’ll support you with relocation and Visa application.
