Job description

Do you have solid PHP and Symfony experience and want to work somewhere where an Engineer has a real say in how projects are built, not just a list of tickets to close?

You’re in the right place.

We’re looking for an independent PHP Engineer who enjoys varied client projects. Someone who can turn an incomplete brief into the right questions, sensible technical choices, and a realistic estimate, and then help build the solution to a high standard.

We assume you know how to write good code. What matters just as much is that you can look beyond it: think about performance, security, and accessibility, talk to clients, and speak up when you see a better way to do something.

And if Cursor is already one of the first tools you open at work - even better.

AI is part of our everyday workflow, not a side experiment. We want AI to make us faster and better, without switching off critical thinking or lowering the bar for quality.

Who are we?

Hi! We’re ambiscale.

We’re a one-stop shop for digital solutions. We build and support web and eCommerce products, from custom development through optimization and DevOps/FinOps to long-term maintenance.

We work with clients across Poland, Europe, and the US, including Żabka, Biedronka, Brand24, and the University of California (Berkeley). Our projects and technologies vary, so you won’t be stuck in one product or one context for years.

What will you be doing?

• Building and scaling enterprise web applications and API-first architectures,
• Looking at client briefs, spotting what is missing, and asking the right business and technical questions,
• Breaking projects into modules, choosing technologies, and preparing realistic estimates,
• Taking care of performance, security, accessibility, tests, and code quality,
• Profiling and optimizing applications and integrating external systems, payment gateways, and APIs,
• Working closely with clients, Project Managers, Front-end Developers, DevOps, and QA,
• Sharing your ideas and helping us improve our architecture, tools, and workflow.

What do we expect from you?

• At least 5 years of commercial experience in a Backend/PHP role,
• Very good knowledge of modern PHP (8.2+) and Symfony,
• A solid understanding of software architecture, including SOLID, Design Patterns, Clean Architecture, and the basics of DDD/CQRS,
• Experience with caching, queues, asynchronous processing, and message brokers,
• A practical approach to tests, static analysis, code review, Git, and CI/CD,
• Experience building secure RESTful or GraphQL APIs and solving performance issues,
• Confidence using AI in your everyday work, together with the habit of checking what it produces,
• Comfort with varied client projects, changing contexts, and briefs that do not arrive perfectly complete,
• Experience estimating work, naming assumptions and risks, and asking for missing information,
• The ability to explain technical decisions clearly (also to clients),
• Fluent English and Polish (at least B2),
• Independence, ownership, and the willingness to give and receive honest feedback.

Bonus Points For

• Sulu CMS or other PHP frameworks, such as Laravel or Laminas,
• Frontend experience with React / Next.js or Vue / Nuxt.js,
• Modern PHP runtimes such as FrankenPHP, Swoole, or RoadRunner,
• Docker, Kubernetes, cloud platforms, Headless CMS, or Composable Commerce.

What’s in it for you?

• Real influence on architecture, estimates, technical standards, and how we deliver projects,
• Involvement in the whole project, not only the development stage,
• Space to suggest better tools, solutions, and ways of working,
• Cursor and other AI tools as a natural part of your everyday workflow,
• Diverse, non-trivial projects for clients from different industries,
• A chance to work across different technologies instead of maintaining one product for years,
• Close cooperation with an experienced Tech Lead and Developers who are happy to share knowledge,
• Access to specialists in AI, DevOps, SEO, data, and Cyber Security within our tech hub,
• Honest feedback, useful code reviews, and people you can actually ask for help,
• A team that values independence without leaving you alone with every problem,
• A culture where quality, security, performance, and accessibility genuinely matter,
• Flexible hours,
• No culture of regular overtime (if extra hours happen, we prefer to give the time back),
• Apple or Windows equipment, whichever works better for you,
• Salary: 14–20k PLN/month (B2B), depending on your experience.

What does the recruitment process look like?

• Intro meeting with our Tech Lead (1h),
• Technical interview with a practical task (2h),
• Final conversation and offer (30 min).
