About SINGU

At SINGU, we’re redefining how the world’s most ambitious real estate companies run their operations. 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.

About SINGU

SINGU is one of the fastest-growing PropTech companies in Europe. Our platform manages over 200 million sqm of commercial real estate for 500+ clients in 35 countries, helping property managers digitalize and automate their operations - from maintenance and inspections to portfolio management.

We value adaptability, collaboration, trust and ambition, and we put our clients at the heart of every decision.

About the Team

The TAM (Technical Account Management) area delivers customizations, dedicated functionality and system integrations for SINGU’s largest enterprise clients - international leaders in logistics and commercial real estate such as Prologis, P3, CTP and AmRest.

Following the onboarding of a new strategic enterprise client, we are establishing a second TAM team dedicated to tailoring the SINGU platform to this client’s operations. The team will be responsible for the full lifecycle of the client’s customizations - from discovery and solution design, through integrations and data migration, to delivery, rollout and continuous improvement.

We are looking for a Tech Lead to take technical ownership of this team from day one. You will define its technical direction and ways of working, act as the primary technical point of contact for the client, and ensure that every customization is delivered in a way that remains consistent with, and sustainable for, our shared multi-tenant product.

The domain is demanding: requirements originate from complex business processes and evolve over time, while security, data integrity and database performance are non-negotiable.

Tech Stack

• Backend: PHP 8 (Phalcon), REST APIs, Redis, background job queues

• Frontend: React (TypeScript)

• Mobile: Flutter (delivered in collaboration with the wider TAM team)

• Database: PostgreSQL

• Tooling: Git (Git Flow), Docker, CI/CD, PHPUnit, PHPStan

• AI-assisted development: Claude / Cursor / Copilot are part of our daily workflow

What You’ll Bring

Must-have

Communication (English & Polish) - Fluent English (C1) - you run workshops, discovery calls and status meetings with international clients independently, without a translator or intermediary - Fluent Polish - the team works in Polish internally - You can turn a vague business request into a clear technical scope, explain trade-offs to non-technical stakeholders, and say “no” or “not yet” with arguments - Experience writing specifications, solution designs and estimates that clients sign off on

Technical leadership - 1+ year as a Tech Lead (or equivalent) of a product/delivery team of 3+ engineers - You own architecture and technical decisions - and are accountable for them in production - You decompose epics into well-defined, estimable tasks before coding starts (Definition of Ready, API contracts, backend/frontend split) - You make delivery predictable: planning, estimation, managing ad-hoc client requests, protecting the team from context switching - You raise the technical bar of the team: code reviews, mentoring, technical onboarding, engineering standards

Engineering - 5+ years of commercial PHP (7.4+/8) at scale - clean, testable, maintainable code - Production React experience (TypeScript preferred) - Strong PostgreSQL - schema design, performant queries, migrations, execution plans - Designing and owning REST APIs and integrations with external systems (imports, exports, SSO) - Security‑by‑default mindset (input validation, access control, data protection) - You actively use AI tools in your workflow and can guide the team in using them well

Nice to Have

• Enterprise / customization-heavy B2B SaaS background (multi‑tenant, per‑client variants)

• Experience with ERP or enterprise integrations (SAP, Dynamics, PeopleSoft), SFTP/CSV/API imports

• Phalcon framework

• AWS, Docker, Kubernetes, CI/CD pipelines

• Mobile (Flutter) awareness

• Improving developer experience: local environments, test automation, CI speed

What You’ll Do

• Own the technical direction of the new TAM team - architecture, code quality and delivery

• Establish the team’s ways of working - delivery process, Definition of Ready/Done, code review standards and technical onboarding, aligned with SINGU engineering practices

• Act as the primary technical contact for the client - requirement workshops, solution design, estimates, technical status updates and escalations (in English)

• Translate client needs into specifications and tasks the team can deliver without surprises; own the final technical specification

• Own sprint planning, estimation and prioritization, balancing committed scope with ad‑hoc client requests in alignment with account managers

• Make architectural decisions for customizations so they don’t fragment the core product; align with Platform/Core teams and the Chief Architect

• Review code, mentor engineers, run technical onboarding for newcomers

• Drive engineering improvements in the team: testability, local environments, automated tests, CI

• Stay hands‑on - roughly 40–60% of your time building and reviewing production code

This is a technical leadership role, not a people‑management role - performance reviews, compensation and hiring decisions remain with the Engineering Manager.

You’ll report to the Engineering Manager and work closely with account managers, QA, the Head of Software Engineering and the CTPO.

Why This Role

• A greenfield opportunity - you shape the team’s architecture, engineering practices and technical standards from the ground up

• Strategic visibility - you lead the technical partnership with one of SINGU’s most important enterprise clients

• Technically demanding work - enterprise integrations, data, performance and security, far beyond standard CRUD

• A balanced role - technical leadership, client engagement and hands‑on engineering in one position

If this role sounds like a good fit, we’d love to hear from you.
