Are you ready to join us and shine brighter in the industry’s most exciting rocket-ship?\nJob Details\n Engineering\n Belgium - Ghent\n Full-Time/Hybrid\nWhat you will do\nYou'll join our Crawler Engineering team as a Backend Engineer focused on data acquisition. This is a building role: you'll design and develop high-performance systems, mostly in Rust, that collect billions of data points from the web. The work sits where backend engineering meets how the web works: HTTP stacks, proxies and browser tooling. When a data source blocks an approach, you'll dig into what's happening on the wire and find another way forward. You'll also help make our infrastructure \"agent-friendly\", so other teams can safely build on it with AI.\nWhere you will have impact\nDesign, build and improve backend systems for data acquisition that handle close to 200 million requests a day.\nWork on our in-house proxy layer and browser tooling: request routing, connection handling and protocol-level behaviour.\nInvestigate hard crawler problems, test alternative approaches when one gets blocked, and turn what works into robust, reusable systems.\nBuild clear interfaces and guardrails so other teams and AI agents can use what you build reliably.\nOwn the quality of your code, including code written with AI assistance: tests, observability and maintainability.\nWork closely with crawler engineers, DevOps and Security to ship solutions that are secure and scalable.\nAbout our team\nThe Crawler engineering team makes sure Lighthouse customers get fresh, high-quality rates, ranking and supply data. We handle close to 200 million requests a day across 200+ data sources, so the team carries a big responsibility for keeping our crawling infrastructure reliable, efficient and ahead of a web that keeps changing.\nWhat's in it for you?\nFlexible working environment: Work from home or at one of our global offices.\nFlexible time off: Autonomy to manage your work-life balance.\nCollaborative team: High-bar, friendly, creative, and passionate colleagues.\nCareer development: Workshops, frameworks, tools, training, and processes to realize your full potential.\nImpactful work: Shape products relied on by 85,000+ users worldwide.\nMobility options: Mobility budget or company car (based on your job category).\nCompetitive compensation: Proactively maintained to value your work.\nNet allowance: to support home office related expenses.\nVouchers: lunch vouchers & eco vouchers.\nComprehensive health insurance: Extensive coverage for you and your dependents.\nPension funding: Group insurance to secure your future.\nReferral bonuses: Earn rewards for bringing in new talent.\nWho you are\nYou have hands on experience building, deploying and running production backend services in a cloud environment.\nYou're experienced with a systems language such as Rust or C/C++, or you have a strong track record in another backend language and a real drive to go deep in Rust.\nYou have a solid grasp of how the web works under the hood: HTTP, TCP/IP, TLS and proxies.\nYou have an R&D mindset. You're curious about how browsers and network stacks work internally, you're comfortable with ambiguity, and you'd rather prove a hypothesis than assume it.\nYou have strong analytical and debugging skills. You're comfortable with packet captures, profilers and reading other people's source code.\nYou communicate clearly, share your opinions, welcome feedback and work well in a team.\nYou're fluent in English.\nTechnologies you will work with\nRust, TypeScript/Node.js, Python, Google Cloud, Kubernetes, Prometheus, Grafana, Claude Code.\nDiversity, equity, inclusion, and belonging\nThank you for considering a career with Lighthouse.
