Senior Software Engineer & Technical Leader

This job is brought to you by Jobs/Redefined, the UK's leading over‑50s age inclusive jobs board. Are you a Software Engineer who thrives on real ownership? At Perk, we know that we feel most fulfilled when we can own the problem and the solution. This means taking responsibility for the entire lifecycle of a feature, from understanding what our customers' pains are with our product team, design documents, coding to deployment, and measuring impact. You will see how your technical decisions move the needle for our customers daily. We prioritize autonomy and pragmatism, giving you the space to solve complex problems without unnecessary friction. Engineering excellence here is measured by the reliability and simplicity of the systems you build to power a global platform.

Responsibilities

• Shape the bigger picture. You won't just build features, you'll refine the what to build and why. At Perk, senior engineers are expected to go beyond the technical solution and focus on the problem itself. You'll contribute to your squad's quarterly goals and long‑term vision alongside your Product Manager and Engineering Manager.
• Architect for today and tomorrow. When a big change is needed in how our platform works, you'll be the one writing the design documents that lay the foundation. You'll become a guardian of your team's technical quality; spotting areas of investment, proactively managing technical debt, and making sure we don't let 'busy work' crowd out the work that truly matters.
• Lead across boundaries. Your influence won't stop at your own squad. You'll communicate complex ideas across multiple teams, proactively identify who needs to be involved, and drive alignment across the broader organisation.
• Raise the bar for everyone around you. Senior engineers at Perk are mentors, coaches, and bar raisers. You'll support less experienced colleagues through direct mentorship, thoughtful feedback during reviews, and by modelling what great engineering looks like in practice.

Desired Skills and Experience

• Product Leadership: Translates complex business goals into technical roadmaps; de‑risks ambiguous projects through spikes and prototyping.
• System Architecture: Architects scalable, evolvable systems and data models that account for performance, failure isolation, and long‑term maintenance.
• Technical Standards: Defines and upholds engineering excellence, including CI/CD optimizations, testing strategies, and coding standards across the stack.
• Frontend Strategy: Establishes frontend architecture patterns, including state management, performance budgets, and comprehensive testing (e.g., E2E/Cypress).
• Backend Excellence: Engineers sophisticated backend solutions involving API versioning, caching strategies, and complex data migration plans.
• Operational Maturity: Leads observability and SRE practices; defines SLOs, manages incident responses, and conducts blameless post‑mortems.
• Security & Risk: Oversees operational security, including secrets hygiene and dependency risk management, to ensure a hardened production environment.
• Mentorship & Influence: Levels up the engineering organization through active mentorship, leading design reviews, and influencing the product roadmap with technical data.
• Cross‑Functional Impact: Coordinates multi‑team deliverables and aligns stakeholders to resolve technical blockers across the organization.
• AI‑Driven Development: Experience with or a strong interest in modern AI‑augmented workflows.
