Stellar Logic

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 Team Lead / Senior Full-stack .NET Developer to join an existing engineering team and help strengthen technical ownership, delivery clarity, and client communication.

This role is for someone who enjoys staying close to the code, but also wants to influence technical decisions, guide other developers, improve engineering standards, and act as a reliable technical point of contact.

What You’ll Do

Hands-on Development: Build and improve backend and frontend parts of the system using .NET / C# and Angular.

Technical Leadership: Take ownership of technical decisions, code quality, implementation approaches, and engineering standards.

Team Coordination: Support planning, estimation, task decomposition, code reviews, and technical alignment within the team.

Architecture: Participate in system design, distributed architecture, integrations, scalability, and maintainability improvements.

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
• Experience with relational and/or NoSQL databases, ideally PostgreSQL and/or MongoDB
• Understanding of distributed systems, scalability, maintainability, and technical trade-offs
• Experience with cloud environments, preferably Azure and/or AWS
• Understanding of CI/CD processes and modern development workflows
• Previous experience as a Team Lead, Tech Lead, Lead Engineer, or in a role with similar technical responsibility
• English B2+ for direct communication with international clients
• Ownership mindset: ability to take responsibility for technical decisions, delivery risks, and the final result

Will be a plus:

• Experience with Kubernetes, Azure DevOps, Terraform / ARM / CloudFormation
• Experience with retail, e-commerce, logistics, supply chain, pricing systems, or internal enterprise systems
• Experience working in outsourcing / outstaffing or another client-facing environment
• Experience mentoring developers or coordinating a small engineering team

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.

Tax and accounting support: We help with the administrative side so you can focus on your work.

Professional development: We support learning, certifications, and growth within your role.

Long-term collaboration: We aim to build stable cooperation, transparent communication, and a working environment where people can do their best work.

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.
