Job description

What it’s all about

Staria’s BI & Planning solutions help companies turn complex business data into clear insights and smarter decisions. The product you’ll be working on, Naviloq, is our modern BI & Planning platform designed to handle large, diverse datasets and transform them into meaningful, actionable information.

You’ll join a tight‑knit product development team of seven developers, including two software architects, working closely with a Scrum Master / QA Lead and Product Owners. The team also collaborates actively with our service organization, whose customer insights influence what we build next. Together, you’ll evolve a platform that continues to grow in performance, capability, and impact for customers across multiple industries and countries.

How you’ll make a difference

As a Senior Software Developer, you’ll take an active role in shaping the data engine behind Naviloq. Your main focus will be on database design and development – ensuring that the platform can process large, complex datasets efficiently and reliably as it continues to grow.

You’ll work across the full lifecycle of new features, from early technical discussions and architectural decisions to implementation, optimization, and long‑term maintenance. This role gives you both ownership and influence – especially in the areas where data modelling, performance, and scalability intersect.

In practice, you will:

• Design, implement, and maintain database solutions that power the Naviloq platform, with a strong focus on functionality, scalability, and reliability.
• Develop new product features together with the team, taking responsibility for the database layer.
• Work with large and complex datasets, ensuring that data processing and queries are optimized for performance.
• Contribute to feature planning and technical design, providing effort estimates and input during sprint planning and prioritization discussions.
• Take ownership of components or features that align with your expertise and interests, becoming the go‑to expert for the areas where you bring the most value.
• Investigate and resolve bugs, troubleshoot issues, and ensure the system continues to operate smoothly as it evolves.
• Participate in code reviews, technical discussions, and architecture planning, helping the team maintain high engineering standards.

Your everyday at Staria

We are seeking candidates based in the Helsinki area. Staria’s hybrid work model offers the best of both worlds: modern office in the heart of Helsinki, combined with the flexibility to work remotely. To ensure smooth collaboration with your team and stakeholders, we hope you’re able to spend a few days per week at the office on average.

The salary typically falls within the range of €6000–7000/month depending on experience, skills, and the scope of the role. The holiday bonus is distributed evenly across your monthly pay, so it’s part of your regular salary.

Keys to success in this role

• Deep database expertise: Strong experience in designing, developing, and optimizing relational databases. Experience working with PostgreSQL databases is essential for this role, and previous exposure to PL/pgSQL is a valuable plus.
• Software development: At least four years of hands‑on development experience.
• Analytical thinking: A structured approach to problem solving and the ability to design efficient data processing logic in a data‑intensive environment.
• Collaborative mindset: Comfortable working closely with developers, architects, product owners, and service teams to deliver high‑quality features.
• Proactive problem‑solving: Initiative to investigate issues, troubleshoot independently, and navigate unfamiliar areas when needed.
• Clear communication: Ability to articulate technical concepts clearly and contribute meaningfully to discussions, reviews, and planning.
• Ownership and adaptability: Willingness to take responsibility for specific components, adjust to changing priorities, and share knowledge with the team.

Why join us

• Startup feel with real stability: Enjoy the ownership, agility, and influence of a small product team – backed by the resources and long‑term stability of a larger company.
• Room to grow and shape your role: We trust our developers. You’ll have the freedom to drive improvements, influence technical decisions, and leave a visible mark on how we build and evolve Naviloq.
• A tight‑knit, experienced team: Work closely with skilled colleagues who value collaboration, knowledge sharing, and continuous improvement.
• Flexibility that supports real life: Benefit from flexible working hours and a hybrid setup that lets you combine focused remote work with meaningful in‑person collaboration.
• A great place to connect: Team days, office breakfasts, and shared events help us stay connected and build a strong team culture.
• A workplace people genuinely enjoy: Our Great Workplace certification reflects what matters most to us: trust, teamwork, and a culture where people feel supported and want to stay.
• Stable growth and solid finances: Focus on your work without worrying about the ground shifting under your feet.
• A modern office you’ll love: Rooftop views, quality coffee, quiet focus areas, and a welcoming crew always ready for a chat or lunch break.
• Benefits that make everyday life smoother: Lunch, phone, and recreational perks are all part of the package.
