We are looking for a senior developer who wants to quickly take on significant responsibility for a product in production and grow into the role of CTO in about 12 months. We are a Finnish start-up whose mission is to build the world’s best tools for helping others. Our business comes from municipalities and cities, which can use our free platform as a platform for civic engagement. Our product has been out for years and we have paying customers. This year, our focus is on:
- building significant new features
- launching AI-assisted functions in the control panel,
- conducting retention-related experiments and automation,
- and keeping the current application functional and smooth.
The technical founder (CEO) is currently hands-on. We want to quickly share responsibility so that you become the second “engine” of development.

What will you be doing (0–6 months)
- You will deliver new features end-to-end (full-stack) and participate in design/specification.
- You manage significant projects (e.g., control panel rework + AI assistant) in a way that keeps quality and delivery in balance.
- You will build and develop the technical side of retention experiments (instrumentation, automation, communication).
- You will participate in bug fixes and production “firefighter” responsibilities with the team.
- You will take charge of the system setup and overall picture (deployments, integrations, data, release paths).
CTO track (6–12 kk)
- Technical direction/architecture and ownership of implementation plans.
- Backlog/project management together with the founder.
- Recruitment and team development (identifying needs, participating in selection processes, onboarding).
- Security/compliance criteria (we will recruit additional staff for this if necessary).
- In the longer term, transition to 50/50 product ownership: business requirements from the founders, technical plans and implementation paths from you.
What we expect from you
Mandatory
- At least ~5 years of experience in programming and proven track record in a production environment.
- Full-stack approach and ability to take ownership of large entities.
- Experience or strong readiness to work with our stack: JS / PHP & Laravel / React Native / AWS / Postgres / MongoDB.
- Ability to specify and plan: you translate business requirements into a clear implementation plan.
- Good team skills: communication, prioritization, and cooperation are critical in everyday life.
Bonus
- Experience in a start-up environment and rapid experimentation.
- Experience with retention/A/B testing, message automation, and measurement.
- Building AI functions into the product (guardrails, measurement, cost/latency).
Location and practices
- Finnish is not a mandatory language. Nationality is not a restriction.
- We expect you to be ready to move to Finland within 6–18 months if you live outside Finland.
- We expect those living in Finland to be available to visit our Tampere office from time to time. Those living abroad can start remotely, and we also organize work periods together on site.
- 6-month trial period. Salary from the start, after the trial period an option model based on performance. Salary: €5,000/month.
Decision-making and autonomy
The founders are responsible for the product vision and strategy. You will have a high degree of autonomy in implementation, experimentation, and improvement. Major, permanent, and costly changes are made jointly, based on the business case and strategy.
