Tieto Banktech powers some of the Nordics’ most trusted banking systems with secure, reliable, and scalable solutions. Using automation, data, AI, and cloud, supported by hands-on guidance, we help banks modernize their core, strengthen trust, and deliver greater impact across the banking experience.

We are seeking a Senior Software Engineer who is both hands-on and strategic, to play a pivotal role in modernizing and leading the development of our Equity post-trade platform. Working closely with the Product Manager, you will spend the majority of your time coding while shaping the architecture, mentoring the team, and driving the transition from legacy monolithic systems to modular, maintainable, and scalable solutions.

Key Responsibilities

• Hands-on Development: Architect, design, and implement robust solutions, with a focus on RESTful APIs, microservices, and domain-driven design.

• Legacy Modernization: Lead the refactoring of monolithic, DB-driven systems, lifting business logic out of stored procedures into modular and maintainable components.

• Technical Leadership: Mentor and guide a distributed engineering team (Stockholm & Pune), promoting best practices, clean code, and technical excellence.

• Architecture Strategy: Collaborate with Product Manager to define and implement a technical roadmap aligned with business goals.

• Quality & Resilience: Drive initiatives to improve code quality, reliability, and maintainability in complex systems.

• Business Collaboration: Translate complex business workflows into technical solutions while balancing speed, scalability, and risk.

Required Skills & Competencies

• Strong programming experience in SQL, C#, and .NET, with a track record of hands-on coding in production systems.

• Proven experience in API design, microservices architecture, and domain-driven design.

• Track record of driving technical transformation in legacy systems.

• Demonstrated ability to modernize legacy, DB-heavy systems, refactor monolithic codebases, and implement modular architectures.

• Experience leading and mentoring distributed teams, fostering knowledge sharing and technical growth.

• Familiarity with CI/CD pipelines, cloud platforms (Azure), Git, and DevOps practices.

• Excellent analytical, problem-solving, and communication skills.

Preferred Qualifications

• Master’s degree in Computer Science or a related field.

• Experience in Equity post-trade or Capital Markets systems.

• Understanding of equity trading workflows and complex business scenarios.

• Minimum 7 years of experience working on enterprise-level solutions.

• Hands-on experience with containerization technologies (Docker/Kubernetes) and cloud-native architectures.

• Experience working in a product organization with strong collaboration between tech and business.

We offer a unique opportunity to shape the architecture of a critical banking platform, work on meaningful projects, and influence a growing, distributed team.
