Job description

impact.com is the world’s leading commerce partnership marketing platform, transforming the way businesses grow by enabling them to discover, manage, and scale partnerships across the entire customer journey. From affiliates and influencers to content publishers, brand ambassadors, and customer advocates, impact.com empowers brands to drive trusted, performance‑based growth through authentic relationships. Its award‑winning products—Performance (affiliate), Creator (influencer), and Advocate (customer referral)—unify every type of partner into one integrated platform. Today, over 5,000 global brands, including Walmart, Uber, Shopify, Lenovo, L’Oréal, and Fanatics, rely on impact.com to power more than 225,000 partnerships that deliver measurable business results.

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:

• 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
• Test‑Driven Development – when and where it makes sense
• Clean code and knowledge sharing

Benefits and Perks:

• 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.
