Stellar Logic specializes in custom IT solutions for international clients. We help businesses build internal systems and enterprise software that power their operations — from complex business logic to full-scale automation.

We’re looking for a hands-on Tech Lead / Senior Full-stack .NET Developer to join an existing engineering team and help strengthen technical ownership, delivery clarity, and client communication.

Cloud & Infrastructure: Work with cloud environments, Kubernetes, CI/CD, and infrastructure-related tasks.

Client Communication: Communicate directly with the client on technical topics, clarify requirements, explain risks, and propose solutions.

Mentoring & Support: Help developers of different seniority levels through technical guidance, knowledge sharing, and practical support.

What We’re Looking For

Must-have:

• 5+ years of commercial software development experience
• Strong hands-on experience with .NET / C#
• Practical experience with Angular
• Experience with APIs, integrations, backend services, and complex business logic

Why Work with Us?

🛠 Built around custom solutions
At Stellar Logic, we work on systems shaped around real business processes, not templates. Our projects often involve complex logic, integrations, internal workflows, and product decisions that require thoughtful engineering.

🎯 Small teams, meaningful ownership
You won’t be one of many people in a large structure. We work in focused teams where each person has visible impact, takes ownership of their part, and can influence both technical and product decisions.

⭐ Quality over quick fixes
We care about building software that is clear, reliable, and maintainable. Good engineering for us means understanding the problem, thinking through the solution, and delivering work that the team can build on.

🤝 Close collaboration with clients and teams
Our work requires direct communication, trust, and context. You’ll collaborate closely with people who care about the result — from engineers and designers to business stakeholders.

🚀 Room to grow with responsibility
Growth at Stellar Logic comes through ownership: taking on more complex tasks, leading initiatives, improving processes, mentoring others, or deepening your technical expertise.

What We Offer

Remote-first cooperation: Work from anywhere while staying connected with your team and international clients.

Flexible working hours: We value autonomy and trust, with core meetings for team and client alignment.

Paid vacation and sick leave: We support a healthy balance between work, rest, and personal life.

Not Meeting Every Skill?

Don’t worry if you don’t match every single requirement.
If your experience is close to what we’re looking for, you enjoy solving complex problems, and you’re ready to take ownership, we’d still be happy to talk.
