Working with core technologies including Python, PHP, Kafka, PostgreSQL, and ClickHouse, you will design scalable, highly available systems that transform raw maritime telemetry into real-time actionable insights for global shipping and commodity markets. Operating with high autonomy under a \"you build it, you run it\" engineering culture, you will play a crucial role in modernizing core services, elevating technical standards, and collaborating with cross-functional partners and client-facing technical teams.\nKey Responsibilities\nArchitect and scale backend services: Design, build, and maintain high-throughput backend applications and microservices using Python and PHP.\n\nBuild real-time streaming & analytical pipelines: Leverage Kafka and ClickHouse to stream, process, and analyze massive volumes of real-time maritime tracking data.\n\nOptimize data persistence and storage: Manage relational and analytical databases, optimizing PostgreSQL queries and ClickHouse schema designs for low-latency queries at scale.\n\nOwn production health and reliability: Implement robust monitoring, alerting, and observability frameworks while maintaining operational ownership across staging and production environments.\n\nDrive cross-functional collaboration: Partner closely with Product Managers, Tech Leads, Cloud Platform teams, and client-facing technical teams to deliver features aligned with customer needs.\n\nElevate engineering standards and mentorship: Guide peer engineers through technical design reviews, code quality benchmarks, and architectural best practices within the Maritime domain.\n\nExperience & Background\nWhat you'll need (Must-haves)\nSenior-level backend experience: ~5+ years of professional software engineering experience developing, scaling, and maintaining complex production backend systems.\n\nCore tech stack mastery: Strong proficiency in Python and PHP alongside deep experience with relational databases like PostgreSQL.\n\nEvent streaming & analytical data tech: Hands-on production experience with Apache Kafka and high-performance analytical data stores like ClickHouse.\n\nSystem design & API development: Proven track record designing RESTful APIs, distributed microservices, and high-concurrency architecture.\n\nOperational mindset: Strong background in CI/CD pipelines, containerized deployments (Docker/Kubernetes), and production observability/monitoring tools.\n\nNice-to-haves\nMaritime & geospatial domain knowledge: Familiarity with vessel AIS data, geospatial systems, logistics, or global trade datasets.\n\nLegacy modernization: Track record of refactoring monolithic architectures into event-driven, decoupled microservices.\n\nCloud infrastructure: Experience with AWS cloud services and infrastructure-as-code (Terraform).","description_format":"text","description_chars":2978,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Data Providers & Datasets","Supply Chain & Logistics Software","Financial Data & Market Intelligence"],"lifecycle":[{"event":"open","at":"2026-09-23T22:23:16Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Senior or Specialist Worker, Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Global Business Mobility: Senior or Specialist Worker;
