What We're Looking For
At Vitec Tietomitta, we're looking for a senior software engineer. The role is deliberately broad — architecture, product decisions, and hands-on delivery — on a small senior team where AI agents do a large share of the implementation and your judgment does the rest. Judgment is what we're really hiring for — it's the part we can't teach. We also require genuine hands-on fluency in Python and TypeScript/React: the agent won't always get it right, and you need to recognize when it hasn't.
Must-have
- Senior-level (10+ years) shipping production software end-to-end, backend and frontend — you've owned systems, not tickets
- Genuine experience delivering multi-tenant SaaS at scale — you've run software in production for many customers and lived with what that brings: releases and migrations without downtime, performance under real load, per-customer configuration, and monitoring
- Fluent, daily use of AI coding agents (Claude Code, Cursor, Copilot or similar) — you delegate implementation, review the output critically, and recognize when the agent is confidently wrong
- Strong architectural understanding — system boundaries, data flow, integration patterns, and the trade-offs between them; able to justify a design, make the call independently, and revisit it when reality disagrees. This is not a ticket-factory role.
- Proactive, customer-driven product behavior — you engage directly with stakeholders and end users if needed, challenge requirements that don't hold up, and optimize for the outcome rather than the ticket
- Hands-on proficiency in Python and TypeScript/React — this is our stack. When the agent stalls or produces something subtly wrong, you need to read and fix the code yourself.
- Fluent English — the working language of the engineering team; codebase and documentation are in English
Things we'd like, but are not a must
- Depth in our specific frameworks — FastAPI, Next.js (app router, server components), PostgreSQL.
- Disciplined separation of data access from business logic — data sources sit behind a clean interface (repository pattern or equivalent), so code can be tested and data sources swapped without a rewrite
- Relational database and data-modelling skills — complex SQL, performance tuning, sensible schema design
- Experience with data-heavy application UX — grids, filters, aggregations, export
- Domain experience in a regulated, reporting-heavy industry — environmental, energy, logistics or similar
- Finnish — a strong plus, but not required; the wider company still operates largely in Finnish, so it helps with domain terminology and stakeholder conversations
Why This Is an Interesting Job
- Breadth of real engineering problems — the work spans product features, data plumbing, and architecture across an established SaaS platform. Expect variety rather than one narrow lane.
- Real impact — you work on software that paying customers use every day, close enough to the business to see what your decisions actually change.
- Domain depth — you go deep on a real business domain instead of skimming a series of tickets. If you like understanding how a business actually works before writing code, that's the mode here.
- AI-first workflow — AI writes most of the implementation. Your job is architecture, domain decisions, context/prompt design, and rigorous review — not typing boilerplate. If you already work this way, you'll be at home; if you don't, this isn't the job.
Why Join
- Circular-economy impact — software that keeps real operational systems running for waste and recycling customers
- Pragmatic engineering culture — long-term quality over short-term delivery pressure
- Senior team — a small group of experienced engineers who value ownership and practical solutions
Working Model
- Direct access to the CTO — for architectural decisions and domain questions
- Proactive by default — you're expected to surface risks early, propose alternatives, talk to customers where it speeds up a decision, and take calls rather than wait for them
- Established engineering practice — existing CI/CD pipeline, code review process, and branching conventions
- Hybrid — approximately 3 days per week at the office
- Office in Pasila, Helsinki — about a 10-minute walk from Pasila train station
- Start immediately — onboarding is ready as soon as you are
