Senior Full Stack Engineer (PHP / Laravel)Nearshore contract, Romania or Bulgaria. B2B basis, starting early October. Full location detail below.What We're Recruiting ForWe're hiring a Senior Full Stack PHP engineer to join a long-term team on a genuinely large-scale online marketplace. Very few platforms handle a product catalogue or transaction volume at this level.The roadmap includes agentic AI workflows built into the platform, retail media integrated directly into the marketplace, and infrastructure work targeting cost and performance at high volume.A lot of this is being attempted at volumes that have rarely been tested in a marketplace before, so the work leans research-led rather than routine.It's a fast-paced scale-up environment on a complex platform. You'll do well here if you're comfortable with ambiguity and shifting ground, and confident enough to advocate for the technical decisions you make.What You'll Be DoingYou'll join the team part-way through a major, multi-year technology transformation.The current client-facing platform runs on PHP and Laravel, and that's where your day to day sits: fixing real issues and building new features within the existing stack.The longer-term direction is a move towards a service-based architecture, with a move to AWS under active evaluation. As that world takes shape, you'll have room to grow into it.This is genuinely end-to-end full-stack work: front-end, APIs, data, auth and the platform that ties it together.This is a long-term role, part of the fabric of the team rather than a short engagement. No juniors. It's a demanding environment, and you'll need to be productive quickly without a long ramp.Who You'll Be Working WithYou'll be engaged by hedgehog lab, a UK digital product consultancy and certified B Corp with 20 years behind us and offices in Edinburgh, Newcastle, Leeds, Manchester and London.We place engineers into long-term client teams on complex, high-stakes platforms.
