Your Role at impact.com:
We’re a team in a fast-growing SaaS scale-up on a mission to make self-service Products, Plans, Subscriptions, and Billing seamless - for clients as well as our sales and account management departments. This is the heart of our business: enabling customers to purchase and upgrade plans independently, while ensuring billing is fully automated, accurate, and scalable.
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.”
