Product Engineer (Web)

Own products and features from beginning to end - originate ideas, understand the strategy and goals behind them, ship to production with real users, iterate on feedback, and stay responsible for their ongoing success.

Scope features and projects, including writing handover / technical design documents (as built) - the person who built a feature is the best person to document it.

Improve application performance - ship technical improvements that make the product faster, more stable, and ready to scale.

Improve how we work, not just what we build: refine development processes, drive improvements in code quality and engineering best practices - and hold a zero-bug standard: bugs get fixed promptly, not stockpiled in a backlog.

Work closely with designers to craft thoughtful UX/UI - ship and own the basic experience using the design system, deciding when to bring in design to polish - and collaborate with the Customer Success team to learn how the product is actually being used.

Bring a tester's mindset - testing is part of building, not someone else's job. You own the quality of what you ship and stand behind it.

3-5 years building customer-facing, full-stack web applications end-to-end as a full-time software engineer - ideally at a product or SaaS startup, high-growth environment, or consultancy with a high engineering bar, where you've shipped real software for real customers and stayed long enough to see the impact of your technical decisions.

Strong on the front-end - you're at your best crafting polished, performance UI (we work in Angular) and you sweat the details users actually feel.

Excellent English & communication: professional working proficiency (C1 level, IELTS 6.0, or equivalent). You don't need the certificates, but you should be comfortable communicating at this level - you can articulate and explain your solutions with confidence in English.

A natural problem solver - you enjoy untangling hard problems and can move confidently from a user's problem to the right solution.

Strong product sensibility: you care about UX, speed, and polish - a genuine love of beautiful, well-crafted work; you want to understand why, and you push back when something doesn't feel right.

AI-native - you naturally reach for AI tools in your daily work to move faster, learn quicker, and raise the quality of what you ship.

High ownership mentality: comfortable working without heavy PM overhead - self-directed, hands-on, takes a feature from idea to shipped, comfortable with ambiguity, knows when to get help, ships something, learns, and iterates.

You move fast because you're having fun and want to deliver value here and now - not because someone's watching you.

A grown-up: low-ego, flexible, kind, considerate, and professional - able to put ego aside when making decisions (this is about attitude, not age or experience).

Proficient in Angular and TypeScript: you've shipped polished, performance UI to production, and RxJS is a given.

Solid understanding of state management (e.g. NgRx, Signals, or equivalent) and when to use what.

Comfortable with front-end performance concerns: change detection, bundle size, rendering data-dense views (grids, schedulers, dashboards), and real-time updates over WebSockets.

Experience designing and building REST APIs in NestJS: DTOs and validation, controllers/services, and keeping the API contract clean for the typed clients that depend on it.

Solid data modeling skills: designing schemas around access patterns, caching with intent. MongoDB experience is a plus; the thinking matters more.

Comfortable working in a large existing codebase: you can read, extend, and build on services you didn't write, not just greenfield projects.

Nice to have: multi-tenant SaaS, event-driven messaging (NATS, RabbitMQ), Socket.IO, Stripe/Xero integrations, or building agentic AI features (we build on Mastra with the Anthropic and OpenAI SDKs).
