Software Backend Engineer, SaaS product (Python) - Greenstep Espoo/Vantaa

Greenstep is a growing, global group helping thousands of companies in Europe to grow through clarity. We are a

technology-oriented company with Finnish roots, founded in 2010. In addition to Finland, we currently operate in Sweden, Norway,

Estonia, Denmark, and the Netherlands. Our team of around 800 experts consists of seasoned professionals in areas such as

accounting, CFO services, financial management, HR, analytics, ERP and CRM technologies, payroll, as well as tax and legal

services. We are an agile growth company, and our service offering continuously expands in line with our customers’ evolving

needs.

Our platform consolidates client operative business data into a single place and turns it into real product capability — BI on

Power BI, integrations, AI/Copilot, MCP, and features built directly on top of semantic models and gold-layer data, not just raw

access to it. As a Backend Engineer, you'll build the AI and agent layer that makes that possible: designing backend services and

APIs in Python/FastAPI, building and orchestrating AI agents with LangChain/LangGraph, and exposing them through MCP — a genuine

strategic bet for us, not a checkbox.

You'll own the service, API, and agent layer end-to-end, from design through deployment, working closely with our data team (who

own the medallion architecture and warehouse modeling) and a dedicated frontend team. You'll sit close to the product owner

driving our scalability and AI/MCP roadmap, with real influence over how agentic features get architected — this is a build role,

not a maintain-what-exists role.

• Design and develop backend services and REST APIs in Python/FastAPI, including agentic workflows built with LangChain and

LangGraph.

• Build features and APIs on top of consolidated semantic-model and gold-layer data — turning data into product, not just serving

it up raw.

• Containerize services with Docker for local dev and deployment — you won't own Kubernetes or infra, but your services need to

ship clean.

• Use AI coding tools to move faster, with engineering judgment intact — we want a builder who uses AI well, not one replaced by

it.

You bring 3+ years of Python backend experience and genuine interest in AI agent systems. This isn't a role for someone who just

wants to consume an LLM API and call it done. You reason well about async and distributed workflows, take ownership of your work,

write clean and well-tested code, and communicate clearly, especially when explaining agent behavior that isn't always

deterministic. We work mainly in Finnish.

• Experience building features on top of semantic layers/warehouses, or integration platforms consolidating multiple source

systems.

Greenstep is a family-owned company founded in 2010 with no loans and a strong balance sheet. Since 2010, we have grown to almost

800 people, more than 3000 customers, and we are looking forward to continuing this growth journey! We provide the full spectrum

of financial services, from accounting to interim CFOs for some of the fastest growing companies in Finland as well as all over

the Nordics. Everyone works closely together, meaning you will be working with other CFO’s, Accountants, Payroll Specialists, HR

specialists, Systems and Integrations Specialists, but most importantly, with great customers. Besides our consulting services, we

already have a large, established tech team with over a hundred people who use programming languages for working with data.

💚 Support for your well-being. For us, everyone's well-being and well-being at work are top priorities. Our occupational health

is comprehensive, and our offices are ergonomically designed. The Flex benefit and lunch discount offered through Epassi are

available to you. However, the number one thing that supports your well-being at work is a sustainably built resource budget.

💚 A salary model that matches your responsibilities and experience. All Greenstep employees are also included in our Together

bonus, through which we share 10% of the annual operating profit among all employees, regardless of role.

💚 Support and time for development and strengthening your skills. At Greenstep, continuous learning is at the core of what we do.

Our own Greenstep Academy offers training in various topics almost weekly!

💚 Career opportunities in a growing family-owned company. We grow organically primarily with a few small exceptions where the

culture has been 100% on par with ours. Because, we want to grow in a controlled manner, profitably and without compromising on

quality. For us, growth means new opportunities: we can make a more positive impact on society, create new jobs, invest in the

development and skills of our personnel, and enable business continuity. Our culture has developed together over the years, and

our values are reflected in our everyday work.

This role is located in our Espoo or Vantaa office. With our hybrid work model, we are at least 50% of the work time at the office

with our colleagues! Please note that Greenstep doesn't sponsor work visas, so to work with us, you need to hold a full-time work

permit and live close to mentioned locations.
