## Description

Want to know how a leading workplace experience and facility management company is powered by technology? At ISS Tech Team, we create smarter workplace experiences through technology. Our Global Technology Solutions team builds digital solutions, from sensors and IoT devices to data, analytics and AI-driven capabilities, that support our ISS A/S operations across Cleaning, Workplace, Food and Technical Services. With tech hubs in Copenhagen, Warsaw, and Porto, and teams collaborating across more than 30 countries, our ISS Tech team develops our digital solutions that have a real impact on both our customers and our people. Location: Porto, Portugal Work regime: Hybrid The Job Role as Senior Software Engineer (PHP): We build the platform people use to order and pay for food and services at work. It sounds simple. It is not. Behind it are three apps, a PHP backend that moves real money in real time, native integrations with payment terminals, printers, scales and scanners, and a long list of payment, identity and workplace systems that all have to agree with each other. Every receipt has to be right, in every country, under every local fiscal rule. And it runs in production for some of the largest organisations in the world, so when you ship something, people use it the same day. As a Full Stack Developer you will build and maintain features across the apps, the PHP backend and the integrations, working from specs and shipping tested code that goes straight to real users. You will go deep on payments, authentication, device integration and multi-country configuration, with senior engineers around you who review carefully and want you to grow. If you have started building with AI and specs and want to get properly good at it, this is a good place to do that. What you’ll do: Start from the spec. We write down what we are building before we build it, and you will help turn product ideas into clear specs and acceptance criteria that product, QA and your AI tools can all work from. Build with AI as a normal part of your day. Coding assistants and agents help us move faster on implementation, tests, refactoring and docs, and you own the result as if you had typed every line yourself. Help us get better at this. Context files, prompt and spec libraries, automated reviews, the guardrails that keep us fast without getting sloppy. We are figuring it out together and your ideas count. Keep the fundamentals strong. AI does not replace good engineering, it amplifies it. Clean code, design patterns, domain-driven design, SOLID, sensible boundaries and tests you can trust are what make the AI output worth shipping. Work on our Angular and Ionic apps (TypeScript, RxJS, SCSS). Three apps, shared libraries, per-customer configuration, theming, and the local and fiscal rules of every country we run in. Make the apps talk to real hardware: barcode scanners, NFC, card readers, printers, scales and POS peripherals through Capacitor and native plugins, and ship them with Android Studio and Xcode. Build on our PHP backend: Slim, PHP-DI, JWT middleware, mPDF, the Google API client, and the endpoints behind authentication, payments, printing and push notifications. Shape the data model in MySQL/MariaDB, write the SQL, and ship schema changes and migrations without anyone noticing. Join design discussions, document what you build, and take part in code reviews on both sides. Key qualifications: Must have : A degree in Computer Science or similar, or the experience that makes it irrelevant. 3+ years building software professionally, with real production experience in Angular and TypeScript. You use AI coding assistants and agents in your actual work, and you review, test and own what they produce. You have worked from specs, acceptance criteria or API contracts and kept the code aligned with them. Solid foundations in clean code, design patterns and object-oriented design, and an interest in domain-driven design and good architecture. The tools change,
