Senior Software Engineer Job at Impact

• This is a high-impact role. The systems you design and build will directly power our revenue growth, unlock new business models, and shape the backbone of how we operate.
• This is not a “business as usual” engineering role. We’re delivering functionality that changes the core of the business, while replacing a legacy monolith with a modern modular monolith – or individual services where it makes sense. While doing this, we strive towards applying best-of-breed technologies and leading-edge methodologies.
• We’re looking for someone who wants to challenge the status quo. Someone who has a strong interest in the latest technologies and engineering practices, and thrives in an environment where curiosity, experimentation, and continuous improvement are part of daily life.

What You’ll Do:

• Take ownership of large, complex problems and design simple, elegant solutions.
• Work with stakeholders across product management, sales, and operations to deeply understand business needs — then deliver technology that meets them.
• Shape our architectural journey: from legacy monolith to modular monolith and event-driven systems, always with pragmatism and best practice.
• Champion domain-driven design (strategic & tactical), hexagonal architecture, test-driven development, and clean code.
• Mentor and guide less experienced engineers, helping the team level up.
• Continuously improve how we work, experimenting with new ideas and raising the bar.

What You Bring:

• BSc in Computer Science or equivalent experience.
• 7+ years’ experience in software development
• Deep foundations in computer science and software engineering (algorithms and data structures, distributed computing, large system design, agile approaches etc.).
• Strong grasp of domain-driven design (strategic & tactical).
• Experience with hexagonal / ports-and-adapters architecture.
• Solid experience with object-oriented and functional programming.
• Passion for simple, clean and readable code.
• Understanding of, and appreciation for, test-driven development.
• Experience designing or working with event-driven architectures.
• A solid understanding of agile and iterative development approaches.
• Grasp of team organisation and dynamics (Conway’s Law, Team Topologies etc.).
• Excellent analytical and communication skills, with the ability to explain complex systems clearly.
• A natural mentor who enjoys helping others grow.
• A true team player — you enjoy close collaboration, value collective code ownership, and believe the best solutions come from working openly with colleagues across disciplines.
• Above all: someone who actively seeks out better ways of building, delivering, and operating software, and isn’t satisfied with “the way things have always been done.”

Our stack:

• Backend: Java / Spring
• Persistence: MySQL
• Frontend: Vue.js (though deep frontend expertise is not required)
• Architecture: Modular Monolith (evolving from legacy monolith), Hexagonal Architecture, Domain-Driven Design, Event-Driven Systems
