Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design, build, and maintain JVM-based microservices on AWS to power a container logistics intelligence platform. Take full ownership of services from architectural design through production deployment and observability.
Requires 5+ years of professional backend experience in Java or Kotlin and fluency in both Polish and English. Must have hands-on production experience with AWS, relational and NoSQL databases, and containerized deployments.
Routescanner is the world's leading container logistics intelligence platform, helping shippers, freight forwarders, and cargo owners discover, compare, and optimize intermodal container routes based on transit times, carrier reliability, and CO₂ emissions. Our platform connects thousands of logistics professionals with actionable, real-time routing data – making global supply chains more efficient, resilient, and sustainable.
We're growing fast, and we're looking for a senior backend engineer who doesn't need hand-holding to thrive.
You'll be a core member of a small, high-ownership engineering team building and evolving the distributed microservices backend that powers Routescanner. You'll work across a complex domain – route optimization, schedule ingestion, geo-routing, and carrier data – at real scale, on AWS.
This is not a role for someone who waits for specs to land in their inbox. You'll take full ownership of services from design through production, make architectural decisions, and proactively identify and fix problems before they become incidents.
Design, build, and maintain JVM-based microservices (Java / Kotlin) running on AWS ECS, App Runner, and Lambda
Work with a rich data layer: PostgreSQL, DynamoDB, RedShift, Redis, and S3
Build and consume event-driven integrations via RabbitMQ and SNS
Collaborate on API design across REST (API Gateway) and BFF patterns
Instrument services with OpenTelemetry, Tempo, Prometheus, and Grafana
Ship via GitHub Actions CI/CD pipelines with Docker and ECR
Work with external integrations including Auth0, GraphHopper, PostHog, and Sentry
Leverage AI-assisted development tools (Claude) as part of your daily workflow
Participate in architecture decisions and technical direction – your opinion will carry weight
5+ years of professional backend development in Java and/or Kotlin
Fluent in Polish and English
Solid understanding of distributed systems design, microservice patterns, and event-driven architecture
Hands-on production experience with AWS (ECS, Lambda, S3, RDS or DynamoDB)
Experience with relational databases (PostgreSQL) and NoSQL (DynamoDB or similar)
Strong command of Docker and containerized deployments
Experience with CI/CD pipelines – we use GitHub Actions
Clean code as a practice, not a talking point – you write code that your colleagues can confidently extend
Genuine ability to self-direct: you can take a loosely defined problem, break it down, make decisions, and deliver
Kotlin specifically (greenfield services are Kotlin-first)
Experience with message brokers (RabbitMQ, SQS/SNS)
Familiarity with observability tooling (OpenTelemetry, Prometheus/Grafana stacks)
Background in logistics, routing, geospatial, or supply chain domains
Experience integrating third-party APIs (auth providers, mapping/routing engines, analytics)
Familiarity with AI-assisted development tools
Small team, high trust – no micromanagement, no approval chains for every decision
GitHub-centric workflow – PRs, reviews, and automated pipelines keep quality high without bureaucracy
Observability-first – we monitor, alert, and fix things before users notice
Clean code culture – we refactor, we review, we don't let tech debt compound silently
AWS-native – we use managed services where they make sense and containers everywhere else
Competitive salary benchmarked to your market
Remote-friendly setup (we care about output, not location)
Direct impact on a product used by global logistics professionals every day
Work in a genuinely interesting domain – intermodal routing is hard, and the problems are real
A lean, senior team where your architecture decisions actually ship
AI tooling as a first-class part of the workflow – not an afterthought
Send your portfolio, CV, and a short message about why you’re the perfect match to us
