Job description

LOCATION

• Primary Location: Malmö / Angelhölm, Sweden

THE OPPORTUNITY

The Boozt platform team is best characterized by its flat structure, a friendly and collaborative atmosphere, and a reputation for solving highly complex problems with simple, elegant technical solutions. Overengineering is something we actively avoid. We work in small, cross‑functional teams of up to five (or max six) developers, within a broader platform community of 176 developers across 5 locations.

Our Warehouse Management System (WMS) is developed fully in‑house, giving us complete control over our engineering priorities, architectural design, and roadmap. Using agile methods and maintaining direct contact with end‑users - our colleagues working inside our own fulfillment center in Ängelholm - we continuously improve the system and ship features to production multiple times per day.

TECH STACK

• Languages & Frameworks: PHP (Symfony framework) and Go.
• Data & Messaging: MySQL, MongoDB, Google Datastore, Redis, and Elasticsearch. Cross‑system communication relies on Google Pub/Sub, RabbitMQ, and standard REST APIs.
• Infrastructure & Support: 100% Google Cloud Platform (GCP) managed via Terraform—no manual ad‑hoc infrastructure changes. While we own our infrastructure, dedicated internal SRE and DevOps teams are always available to collaborate.
• Observability: Datadog for centralized logging, APM metrics, health monitoring, and tracking real‑time performance impact during deployments.
• AI Tooling: We actively leverage AI developer tools (Claude Code, Gemini, Codex, etc.) to accelerate coding, debugging, and research. We embrace modern workflow tools to eliminate friction and focus our time on solving complex logic problems.

WHAT YOU WILL DO

• Model and optimize core logistics algorithms, tackling mathematical and optimization challenges across processes like putaway, picking, sorting, and returns.
• Integrate software services with various European distribution partners and logistics carriers.
• Integrate backend systems directly with physical warehouse hardware (including robotic cubes, robot arms, conveyor networks) using the OPC UA protocol.
• Work directly with Logistics Product Managers and Warehouse Process teams to design, test, and ship real‑time system improvements.

YOUR PROFILE

• At least 4 years of professional experience in backend PHP development.
• Strong hands‑on experience with the Symfony framework.
• Strong analytical mindset with an interest in solving algorithmic, mathematical, or logic optimization problems.
• Open to and enthusiastic about using AI coding tools to optimize daily engineering workflows.
• Fluent in English, our corporate language (only applications written in English will be considered).

BONUS POINTS

• Experience with Go, GCP, or OPC UA.
• Prior background or experience with WMS / WCS development.

We review applications on an ongoing basis. You can read more about the process under Recruitment.

BOOZT PERKS

• Great personal and internal career development opportunities
• A culture built on our values of trust, freedom, and responsibility
• Driven and passionate international colleagues
• A generous employee discount
• Wellness allowance
