Lead Software Engineer (with .NET)

The Role

We’re looking for a Lead Software Engineer (or a strong Senior Developer ready to step up) who wants to make a lasting impact - not just through code, but by shaping how we build and evolve systems that matter. You’ll guide the technical direction across multiple products, support a team of engineers, and lead by example in improving both code quality and engineering culture.

Working with us, you’ll become part of an international team building and modernizing digital solutions for the maritime industry - a critical sector where stability, transparency, and reliability are paramount. Some of our systems are modern, others are complex and deeply embedded - and your work will help bridge that gap.

We value someone who can embrace that mix, improving stability and maintainability while guiding us toward the future. If you’re a strong communicator, technically grounded in .NET, and thrive on leading by example, this is an opportunity to make a lasting impact.

Responsibilities

• Play an active, hands-on role: Work alongside your team — developing, testing, and releasing new features while setting the standard for high-quality code and delivery.

• Lead by example: Drive technical excellence across products, influencing architecture, quality, and maintainability.

• Build for the long term: Balance delivery with investment in foundational improvements — from better observability to CI/CD practices.

• Own technical direction: Collaborate with engineering and product leadership to define and execute on a sustainable tech strategy.

• Modernize legacy systems: Identify opportunities to reduce technical debt and improve performance, reliability, and developer experience.

• Work in an international team - the team consists of people of different nationalities, so all communication is based on English.

• Working in the Agile fashion framework.

Core Skills

• Strong English communication skills (B2+ or higher) - both written and spoken, to collaborate effectively in an international environment.

• Expertise in the .NET ecosystem - including C#, frameworks, and tooling.

• Solid understanding of system design and DevOps - experience with CI/CD pipelines and automated testing strategies.

• Proficient in working with databases - including both SQL and NoSQL, with experience in schema design and query optimization.

• Practical experience with Azure services.

• Excellent communication and leadership abilities – confident in collaborating, guiding, and influencing technical direction.

• Ability to translate business needs into technical solutions and roadmaps – ensuring alignment between delivery and long-term sustainability.

• Proactive, self-driven mindset with strong ownership – takes initiative and drives initiatives from start to finish.

• Exposure to frontend technologies – in any common frontend frameworks.

Nice to Have

• On-premises infrastructure experience – helpful in hybrid cloud environments.

• Understanding of application security principles – including authentication, authorization, and secure coding practices.

• Mentoring and coaching experience.

• Background in improving legacy systems – experience modernizing monoliths, untangling spaghetti code, or transitioning away from stored procedures.

• Familiarity with Agile methodologies – comfortable working in iterative, cross-functional team environments.

What you can expect

Despite our growth, we managed to maintain a relaxed and enjoyable atmosphere of a tightly knit team that can implement complex projects comprehensively and effectively. Each of us knows what is expected from us and has adequate space and freedom of action.

The actual work is important, but it’s also essential for us at Clarksons that we all stay happy, relaxed and motivated. That’s why we provide a wide range of benefits to all our employees:

• Private medical care (Luxmed)

• MyBenefit or Multisport card

• Language courses (English and German)

• Employee referral program

• Paid days off from services (B2B)

• A paid day off to care for your health - “Dzień na U”

• Integration events, joint company trips, birthday celebrations and many other

What we offer

• Competitive salary + discretionary bonus

• Flexible working hours
