C# Developer (AI-First)

CRM Service is looking for experienced C# Developers (AI-First) to join our project implementation team. You will work closely with a Product Owner and Team Lead based in Finland, alongside a Senior Integration Tech Lead, serving Nordic non-profit organisation (NPO) customers.

More information: https://crmservice.com/

We need engineers who go beyond writing code — people who think deeply, take ownership, and build solutions that genuinely make a difference for our customers.

The role and team

You will be an active member of a small, focused implementation team. Your day-to-day work involves building and maintaining and integrating backend systems that power real customer outcomes — not internal tooling. The team operates with a high degree of trust and expects you to take initiative.

• Work directly on customer-facing projects in the Nordic NPO segment together with Product Owners, Project managers and Support people

• Collaborate with a tight-knit, senior-level team across Finland

• Contribute to both architecture decisions and hands-on implementation

• English is the working language – no Finnish required

• We require a minimum of 3 years of professional development experience. This role is not suitable for junior developers.

Technical Skills

Required

• Strong, proven experience with C# and the .NET ecosystem

• Solid back-end development skills — REST APIs, service design, and integration patterns

• Hands-on experience building AI-first applications: integrating LLMs, building agentic workflows, or designing AI-native architecture — not just wrapping an API call.

Nice to Have

• Familiarity with CRM, ESP, or marketing technology platforms is a plus

• Experience with integration hubs or middleware platforms is a plus

The Mindset we value

• You think outside the box — when everyone else follows the obvious path, you ask: “Can we do this smarter with longer-lasting results?”

• You see the big picture and understand how your work connects to and impacts other parts of the system

• You‘re proactive and self-directed — you don‘t wait to be told what to do next

• You care about customer outcomes, not just technical correctness

Communication

• Fluent, professional English — written and spoken

• Able to articulate technical ideas clearly to both technical and non-technical stakeholders

• Comfortable collaborating with an international, remote-first team culture

Experience requirements

We require a minimum of 3 years of professional development experience. This role is not suitable for junior developers.

We accept experience from:

• Professional employment as a developer in a company

• Self-published or open-source projects that demonstrate real-world scope and quality

Formal education is not a requirement — your track record speaks for itself.

Why you’ll love working here:

• You’ll work on meaningful, real-world problems at the intersection of backend engineering and AI – for customers who rely on these systems to drive their mission.

• If you’re the kind of developer who sees AI as a fundamental shift in how software is built (not just a feature to bolt on), this is the right team for you.

What will you get?

• You’ll get to work with experienced software engineers worldwide at a market-leading, innovative Scandinavian SaaS company looking to accelerate growth.

• Scandinavian work culture: creativity, innovation, and work-life balance.

• Competitive salary and 100% official salary during the probation period.

• Annual review and 13th month salary.

• Premium healthcare and accident insurance.

• Wellness package to support employees to stay healthy and financially secure.

• Exciting company outings and team-building activities.

• On-site and training opportunities in the Nordic region.

• Modern working environment.
