Nice-to-haves • Experience with Azure-based delivery pipelines (CI/CD) or cloud-native environments., • Experience with design systems (Storybook), and strong collaboration with Figma workflows., • Familiarity with accessibility (WCAG) and internationalisation (i18n, including RTL languages)., • Familiarity with React (helpful for cross-team collaboration, not required).

Tech Stack (Current) • Frontend: Vue (2 & 3), Nuxt, • Cloud / Delivery: Azure (CI/CD), • Observability: Sentry (and related logging/monitoring patterns) (We don’t expect you to know every tool on day one — we care about fundamentals and ownership.) Life at Keepnet Engineering at Keepnet is about craft, collaboration, and impact. What you can expect: • Hybrid working: In-office collaboration + remote focus time, • Thoughtful engineering: Time to design systems properly, not just ship quickly, • Global context: Work on a multinational platform used across multiple regions, • AI-first environment: AI-assisted development and production-grade AI systems are part of everyday work, • Team culture: Monthly team lunches and quarterly offsites, • Care about clean architecture, maintainability, and product quality, • Enjoy working with experienced peers who challenge each other constructively, • Prefer preventing incidents over reacting to them, • Want to build software used by real customers at real scale, • Believe good engineering is as much about ownership and judgment as it is about code If that sounds like you, we’d love to talk.

What We’re Looking For • 8+ years of experience building backend systems with .NET., • Strong understanding of API design, distributed systems, and asynchronous architectures., • Experience with SQL and NoSQL databases (PostgreSQL preferred), caching, and queuing systems., • Familiarity with cloud environments and DevOps practices (Azure preferred)., • Comfort working on production SaaS platforms, with ownership beyond deployment., • Experience using AI-assisted development tools (e.g. Cursor or similar) to support code exploration, refactoring, testing, or design discussions—while maintaining strong engineering judgment., • A strong sense of ownership and production accountability, including monitoring, debugging, and continuous improvement., • Ability to understand product and business context, making pragmatic technical decisions that balance user value, risk, and long-term goals., • A security-conscious mindset, building systems that are secure by design.

What you can expect: • Hybrid Working: A balance of in-office collaboration and remote focus time., • Thoughtful Engineering: Time and space to design systems properly, not just ship quickly., • Global Context: Work on a multinational SaaS platform used across multiple regions., • AI-First Environment: AI-assisted development and production-grade AI systems are part of everyday work., • Annual Leave: 25 days (+1 per year of service)., • Health & Well-being: Gym support and cycle-to-work scheme., • Team Culture: Monthly team lunches and quarterly offsites., • Continuous Learning: Learn from experienced peers and grow your skills over time. Why This Role Is Different This role is for engineers who: • Care about system design and long-term maintainability, • Enjoy working with experienced peers who challenge each other constructively, • Prefer preventing incidents over reacting to them, • Want to build software used by real customers at real scale, • Believe good engineering is as much about ownership and judgment as it is about code If that sounds like you, we’d love to talk.
