Our mission is to become Europe’s leading platform for managing warehouse, logistics, retail, and multi-site commercial real estate portfolios — empowering our Clients to protect revenue, boost efficiency, and unlock new value across every aspect of their business. Our unified CAFM platform already powers the daily operations of over 250 million m² of real estate worldwide , supporting more than 500,000 professionals. Following our union with the UK’s Micad and Germany’s net-haus, we now help manage 100,000+ buildings across 35+ countries — and we’re just getting started. Backed by a leading growth equity investor, we’re scaling rapidly and partnering with global leaders such as Prologis, ECE, CTP, Hillwood, Logicor, GLP, and Unibail-Rodamco-Westfield. As we continue to grow through strategic acquisitions and bold innovation, we stay true to our core values: adaptability, collaboration, and client focus. If you’re ready to help build Europe’s leading platform for property operations — and make a tangible impact on how the real estate industry works — join SINGU and be part of this transformation. Build the architecture for SINGU's newest revenue line — Project Tracker. The product Project Tracker is SINGU's new module for managing CAPEX/OPEX projects across commercial real estate portfolios. MVP went live early this year. Foundations work, but the architecture for the next few years is still open. Traction is real: 294 people from 110 clients on the waitlist (Prologis, Mapletree, NEPI, Globalworth, Segro). After a demo, Prologis's Director of Global Operations asked for early access. Separately priced module – a revenue line, not a free feature. Alongside Project Tracker, we have several AI initiatives in active development across the platform. As Tech Lead you won't be siloed in one module – you'll have visibility and a seat at the table on the broader AI work shaping where the product goes next. The team Small and co-located in our Kraków office: a PM, a UX designer, a backend developer, a fullstack developer, and a mobile developer, QA sits in a dedicated team alongside us. You'll work shoulder-to-shoulder on the same floor. The stack PHP 8 on Phalcon (monolith), PostgreSQL, React 18 in parts of the UI, TypeScript. What you'll do – honestly This isn't a pure tech role. You'll juggle: Architecture: decisions that stick for years on a module still finding its shape. Requirements analysis & work decomposition: turning client needs into shippable scope. Hands-on development: you ship code. People work: knowing when to call the shot and when to trust the team. What we're looking for: 5+ years commercial PHP (8+), confident with Git, PHPUnit, PHPStan, CSFixer. Fluent in PostgreSQL (schema, performance, migrations). Production React (TypeScript preferred). SOLID, design patterns, REST API design as second nature. You actively use AI tools (Copilot, ChatGPT, Claude) – expected, not nice-to-have. Tech Lead experience: either proven, or you've been making technical and architectural decisions as a senior and are ready to step into the role Polish fluent enough to work daily with the team. English good enough to run client meetings: our clients are a mix of Polish and international, so you'll switch between both depending on the call. Nice-to-haves: Flutter, AWS, Kubernetes/Docker/CI, experience with Phalcon or similar lightweight PHP frameworks. Honest notes Project Tracker is early – a new module still in active development. The MVP is live, but the product is taking shape and you're shaping its architecture, not inheriting it The role is a mix. Hands-on + architecture + analysis + people. If you want to stop coding, this isn't it. No on-call for this role. The practical stuff Salary: 20,000–25,000 PLN net B2B / 16,600–20,750 PLN gross UoP. Hybrid: 2–3 days/week from Kraków office. Top-notch Apple equipment , private healthcare (dental + vision), life and health insurance, sport card, annual training budget, commute subsidy, referral programme, extra day off for medical check-ups, annual team offsite. If this role sounds like a good fit, we’d love to hear from you. Apply and help us build technology that supports critical operations every day.
