We are offering now a set of exciting positions in our headquarters in Athens, across multiple departments and areas of expertise.

We are currently looking for a Tech Lead who will provide hands-on technical leadership across our Software Delivery projects. The role leads the design and development of applications built on .NET/C#, owns code quality and engineering standards, and mentors the engineering team. The Tech Lead coordinates technical requirements with the DevOps/Infrastructure team, drives the adoption of best practices across the SDLC, and acts as the primary technical decision-maker within project teams — while collaborating closely with the Section Manager on significant architectural decisions.

What will you do:

• Lead the technical design of scalable and maintainable solutions, engaging with business and technical stakeholders to translate requirements into effective software architectures.
• Oversee development and testing activities across the Software Delivery Lifecycle, ensuring seamless progression from design through deployment.
• Own code quality assurance by leading code reviews, defining coding standards, and maintaining high engineering practices across the team.
• Coordinate cross-functional delivery teams (engineers, QA, UX), providing technical leadership during project planning and implementation.
• Build and maintain CI/CD pipelines within the development team, collaborating with the DevOps/Infrastructure team on templates, complex pipelines, and infrastructure-related deliverables.
• Ensure solutions adhere to security best practices and information security principles throughout design, development, and deployment.
• Mentor and coach Software Engineers on technical skills, design patterns, and engineering best practices.
• Proactively identify technical delivery risks and either resolve them or escalate with recommended mitigation strategies.
• Lead the evaluation and implementation of new technologies and proof-of-concepts (PoCs) to enhance the team's capabilities.
• Lead application performance monitoring, troubleshooting, and root cause analysis for significant incidents.
• Stay informed about emerging technologies and trends, providing recommendations on technology adoption.

What you will need in order to succeed:

• A BSc in Computer Science, Information Technology, or a closely related field.
• At least 7 years of experience in software engineering, with at least 2 of them in a tech lead or equivalent technical leadership role.
• Expert-level proficiency in C# / .NET, including Web API, Entity Framework, and related ecosystem.
• Strong SQL skills — schema design, query optimization, and data access patterns.
• Solid experience in software architecture and design patterns (SOLID, Clean Architecture, DDD concepts).
• Hands-on experience with React.js or similar modern front-end framework for full-stack delivery.
• Deep working knowledge of Git — branching strategies, pull request workflows, and code review practices.
• Hands-on experience with cloud architectures (Azure preferred).
• Familiarity with DevOps and CI/CD practices, including building and maintaining pipelines.
• Experience working with and leading teams in Agile/Scrum environments.
• Proven ability to mentor engineers and raise the technical bar of a team.
• Strong communication skills — ability to discuss technical topics clearly with both technical and non-technical audiences.
• Excellent English speaking skills.

Nice to have:

• Microsoft Azure certifications (e.g., AZ-204 Azure Developer Associate, AZ-305 Azure Solutions Architect Expert).
• Experience with RPA, LLM integration, or business process automation.
• Exposure to the energy sector or regulated industries.
