• Green-field impact.  You’ll influence architecture, tooling and culture while user numbers are still in six figures, not millions.
• Release velocity. CI/CD on Laravel + Vue gives us idea-to-production in hours, not sprints.
• Product-first crew.  Work shoulder-to-shoulder with brokers, surveyors and designers; watch today’s commit unblock a client tomorrow.
• Career rocket.  Growth targets demand future tech leads and managers—progression isn’t hypothetical.
• Flexible entry points . Junior, mid or senior—prove you can learn fast and own problems, and we’ll tailor the title and package to you.

• Build &  ship  core features in Laravel 10, Vue 3 + Vite, Tailwind and MySQL/Postgres.
• Design clean  APIs  for everything from lender integrations to survey-booking flows.
• Tackle performance —profile queries, cache smartly, keep TTFB sub-150 ms even at peak sales rush.
• Own quality —write tests (PHPUnit/Pest, Cypress), push them to QA, and monitor Sentry/Grafana.
• Pair & mentor —review PRs, run mob-coding spikes, share “today I learned” wins.
• Invent & iterate —spot friction, pitch fixes, build POCs—no permission slips needed. 

• Have 1–8+  years  shipping production code (any modern language). We care how you think, not exactly where you’ve been.
• Can show us side projects, OSS or past  work  that prove curiosity, grit and smart trade-offs.
• Enjoy moving fast —feature flags, A/B tests and “done > perfect (revisit quickly)” are your norm and iterate quickly using AI tools.YES - WE ALLOW CURSOR OR WINDSURF OR SIMILAR to build quickly!  Don't know what they are? Don't believe in the power of AI to code? SIMPLY DO NOT APPLY.
• Communicate clearly with non-tech teammates; you explain latency spikes like you’d explain a recipe.
• Treat problems as puzzles, not blockers, and pull the team with you when the heat is on.

• Salary guidance – we benchmark against UK medians (£42k mid-level; £5k senior) and London uplifts, but we’re flexible for the right person.
• Equity options – share in the upside you’re building.
• Office-first – Norwich HQ 5 days a week (UK-based) - Hybrid and remote is a non-starter in the culture and team we've already built. Do not apply if you want a day or two at home.
• Kit of your choice (M-series Mac or high-spec PC), 27″ monitor, licence budget.
• 25 days holiday + your birthday + “move day” when you buy/sell a home.
• L&D budget, conference tickets, paid time for OSS or learning spikes.
