The role

We’re looking for a Senior Backend Engineer to work at the core of our product-scaling our architecture, shipping powerful features, and solving complex, real-world problems. You’ll collaborate closely with the CTO and the product team. You’ll also leverage AI Coding tools as part of your toolkit.

If you thrive on clean code, scalable systems, crisp communication, and thoughtful product decisions, we’d love to hear from you.

What you’ll do

• Own backend features end-to-end: scope → design → implement → test → ship → observe
• Build production-grade web services and APIs (primarily in PHP with Symfony)
• Write efficient SQL (MySQL) and use Doctrine ORM effectively; tune queries and indexes
• Improve reliability and performance through thoughtful design, profiling, and instrumentation
• Partner with Product and Design to turn requirements into simple, lovable solutions
• Raise the bar on engineering standards, tooling, observability, and developer experience
• Mentor peers (and be open to being mentored); give and receive clear, actionable feedback

How we work withAI Coding tools (and how you will too)

• Use AI Coding toolsto draft tests, migrations, scaffolds, refactors, and documentation-then review with rigor
• Design prompts, tools/functions, and lightweight evaluation harnesses to keep quality high
• Generate test data and edge-case scenarios; speed up root-cause analyses with structured queries
• Build small internal automations (e.g., changelog helpers, lint/PR assistants) that save hours
• Apply judgment: treat AI Coding toolsoutput like a junior engineer’s PR-useful, but you own the result
• Follow our data-safety guidelines when working with customer or production context

You’ll be great at this job if you

• Have 5+ years of backend experience shipping and operating production systems
• Communicate clearly-short, sharp PRs; well-scoped tickets; concise design notes
• Bring product curiosity: you ask “why,” talk to stakeholders, and iterate toward impact
• Have strong experience with PHP (Symfony), MySQL, Doctrine, RESTful APIs
• Know core software design principles and patterns; write maintainable, testable code
• Are comfortable debugging across the stack and making pragmatic, data-informed trade-offs
• Are excited to work withAI Coding toolsdaily and continuously improve how the team leverages them

Nice to have (optional)

• Caching/queues and async processing experience
• Observability (metrics, tracing, logging) and performance tuning
• Security and data-privacy awareness in SaaS environments
• Experience with logistics

• High impact: Small, senior team; your work ships and matters
• Category-defining product: Real-time data, operations research, and ML applied to logistics
• AI Coding tools-forward culture: We embrace new tools responsibly to move faster with quality
