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 customised digitalisation 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, optimisation, 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 modernisation 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 containerised 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 centre 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. In addition, we offer:

• A competitive salary, which within the framework of this role is approximately 5000-6000€/month, depending on your experience level
• Lunch benefit
• ePassi Flex budget of 1 000 €/year
• Mobile phone benefit
• Home internet
• Health and accident insurances
• Bike benefit
• Daily refreshments at the office

Your supervisor will be there to spar on personal learning, career development, and possible training needs.
