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.” 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 Our methodologies: We strive for continuous improvement and use proven engineering practices: • Domain-Driven Design (strategic & tactical) • Trunk-Based Development & Continuous Integration • Continuous Delivery and frequent production deployments • Agile development • Test-Driven Development – when and where it makes sense • Clean code and knowledge sharing Benefits and Perks: At impact.com, we believe that when you’re happy and fulfilled, you do your best work. That’s why we’ve built a benefits package that supports your well-being, growth, and work-life balance. • Flexible Working: Our Responsible PTO policy means you can take the time off you need to rest and recharge. We're committed to a positive work-life balance and provide a flexible environment that allows you to be happy and fulfilled in both your career and your personal life. • Health and Wellness: Your well-being is a priority. Our mental health and wellness benefit includes up to 12 fully covered therapy/coaching sessions per year, with additional dependent coverage. We also offer a monthly gym reimbursement policy to support your physical health. • A Stake in Our Growth: We offer Restricted Stock Units (RSUs) as part of our total compensation, giving you a stake in the company's growth with a 3-year vesting schedule, pending Board approval. • Investing in Your Growth: We’re committed to your continuous learning. Take advantage of our free Coursera subscription and our PXA courses. • Parental Support: We offer a generous parental leave policy, 26 weeks of fully paid leave for the primary caregiver and 13 weeks fully paid leave for the secondary caregiver. • Technology Financial Support: We provide a technology stipend to help you set up your home office and a monthly allowance to cover your internet expenses impact.com is proud to be an equal opportunity workplace.
