Job description

We are looking for a Senior Developer or Architect – someone who has proven they can build and evolve complex software systems and is ready to bring that expertise to projects that power business-critical operations across industries. At Forge, your work enables real business impact for organizations that keep society moving. If that sounds like your kind of work – let's talk.

First, let us tell you more about Forge Digital

We are Forge Digital – a technology agency with cutting-edge solutions and strong domain knowledge in digitalization across manufacturing, retail & logistics, and energy. Our mission is to improve our clients' performance. We guide companies in assessing their current digital maturity, identifying digital challenges and opportunities, and designing a customized digitalization roadmap. We leverage cutting-edge technologies to enhance operational efficiency. Our expertise in analytics, machine learning, edge computing, and sensor-machine integrations enables us to create a sustainable competitive edge.

What we look for

As a Senior Developer or Architect at Forge, you will design and build robust, scalable systems – from operational and business applications to industrial operator interfaces and real-time situational awareness solutions. You will take technical ownership of complex projects, collaborate closely with clients, and help shape how we work.

Here are a few examples of what you could be working on at Forge:

Development of AI-powered solutions: applied AI for decisioning, optimization, and predictive systems, as well as agentic and generative AI capabilities embedded directly into business applications
Development of operational work-enhancing solutions and real-time situational awareness systems
Development of integrations connecting production, business, and automation systems (IT/OT)
Development of data pipelines, data platforms, and event-driven architectures
Business-critical and high-availability system development
Legacy system modernization for AI-assisted development practices

Our main technology stack includes .NET, C#, Node.js, NestJS, and TypeScript – though we are technology-agnostic and always select the best tools considering the entire solution lifecycle. We work with Azure and AWS cloud platforms, hybrid cloud environments, and on-premises solutions.

Fluency in both written and spoken Finnish and English is required.

How to forge success in this role

To succeed in this role, you bring solid hands-on experience in software development and a genuine interest in building industrial-grade solutions. The following are what we consider essential:

AI-assisted development: You are comfortable working in AI-assisted development workflows – using AI tooling to accelerate delivery, improve code quality, and maintain high standards of human oversight.
Software architecture: You can design and own the technical architecture of complex, distributed systems – making sound decisions that consider the full solution lifecycle.
Core technologies: Strong knowledge of most of our main technologies (.NET/C#, Node.js/TypeScript) and databases such as MS SQL, PostgreSQL, and/or document databases.
Container environments: Comfortable working with containerized applications and deploying to Kubernetes or similar environments.
Event-driven architectures: Solid experience designing and building event-driven systems and messaging patterns, using tools such as RabbitMQ or Azure Service Bus.
Domain knowledge: Background in manufacturing, logistics, or energy sectors.
Cloud and infrastructure mindset: Solid understanding of Azure and/or AWS services, cloud-native architectures, and hybrid environments.
Communication & client interaction: As a senior member in a consultancy setting, you are comfortable engaging with clients, facilitating technical discussions, and translating business needs into technical solutions.

The following experience is considered an advantage:

Experience building and integrating LLM-based solutions, including agentic workflows and MCP-based systems
Experience with industrial data exchange standards such as OPC UA or similar IT/OT integration patterns
Frontend development experience (React or similar)
Python and data engineering or analytics background

More than anything, we value a learning-oriented mindset and genuine willingness to keep developing your skills.

What we offer

At Forge, senior developers and architects have real influence over how systems are designed and delivered – you will shape technical direction, define standards, and solve problems that directly affect project outcomes. Our clients operate in sectors where the systems you build genuinely matter.

You will join a highly motivated and experienced team, with whom to build the story of Forge Digital. As a newly established company, we provide a real opportunity to put your mark on how we work, operate, and innovate with clients.

This position is full-time, and the start date is agreed with the chosen candidate. We offer a competitive salary based on your experience level. Our comfy offices in the GO21-building in Tampere and Helsinki city center offer a great atmosphere to work in. We work in a flexible hybrid model and put a lot of focus on building a strong team culture and cohesion.

We offer great employment benefits, which currently include:
