About AmbioAmbio is an AI-driven physical commodity trader on a mission to accelerate the transition to sustainable materials. This mission is progressing fast in our primary domain – recycled plastics.
We work closely with global brands and industrial manufacturers through the full procurement cycle, making sustainable materials an easy choice. The main product we’re building is Ambio Platform – a tool that our team of traders uses daily to run the full sales process and all the operations related to it.
We’re a Helsinki-based startup with 15 employees with offices in Helsinki, Berlin, and Stockholm, and funding from e.g. Lifeline Ventures and Speedinvest.

This role is a great fit for someone who is excited about startups and building with AI in the center. This is an on-site position in our Helsinki office.
Tasks
What you'll do
- Build and maintain full stack features across our React frontend and Node.js backend
- Work with our PostgreSQL database, including schema design, query optimization, and migrations
- Deploy and maintain cloud infrastructure on Google Cloud Platform using Terraform
- Design and implement AI agents and AI workflows that solve real user problems
- Help shape engineering standards as we grow
- Work closely with our commercial team to define and refine our feature set
Requirements
- Signs you would be a great fit for this role:
- Genuine interest to work at a fast growing startup with a high ambition level and to take real ownership in developing the product
- Ability to work across our full stack: Node.js, Typescript, React, PostgreSQL, Google Cloud Platform, Terraform, Github Actions – we don’t expect you to be an expert in everything but the nature of the work is more backend-leaning than frontend and we particularly appreciate expertise with Typescript
- Your ideal work day involves more than picking up tickets from a backlog and building them independently – you enjoy collaborating both with other developers and end users
- You are interested to work in a flexible, but mostly on-site team (office based in central Helsinki)
- Interest in AI-native development: LLM APIs, tool use, retrieval, agent architectures
- You care about code quality and moving fast and can find the right balance between the two
- How we work:
- Every technical decision traces back to a real user problem and we hold ourselves to a high bar in every delivery that touches the customer
- We ship simple, learn fast, and improve continuously – getting to value quickly matters more than perfecting something in a vacuum
- You own your work end-to-end, from the first commit to the outcome it produces.
- We communicate proactively, step up across role boundaries when needed, and take responsibility for shared results, not just individual tasks
- We take the mission seriously, but we don't take ourselves too seriously.
- We hire for work ethic, curiosity, and attitude, not credentials
- No title or role is more important than the work itself.
- We approach each other and our craft with humility, empathy, and a constant drive to raise the bar and improve each day
- Typical recruitment process:
- Intro: get to know each other
- Technical interview: practical interview through examples from real work
- Culture interview: with the founders
- Reference checks from your previous jobs
- Closing: with your future team lead and/or one of the founders
