Senior Java Developer

The ShipMonk systems are designed as a well-architected PHP modular monolith, that we’re operating in Kubernetes. We intend to transform some subsystems into right-sized services and some of them will be rewritten in Java from scratch. This is why we’re seeking experienced Java Developers who are skilled in designing and implementing advanced REST web applications and data integrations - the core of the monolith is here to stay and the services must integrate smoothly.

The “Java team” is led by Filip Procházka and it’s a mixture of ex-PHP developers and “pure” Java developers, so even if you have a strong background in a different language, if you’re interested in Java, we’d still be thrilled to talk with you.

Tech stack:

• Java 21
• Spring ecosystem
• Docker
• Kubernetes (AWS EKS)
• Hibernate
• PostgreSQL
  
• REST APIs
• Very high bar for quality

What does it look like and what we are proud of:

• The main backend application provides a REST-like API for several types of clients (web, autonomous robots, iOS picker devices, microcomputer packers, automatic conveyors and more).
• We have the rest of the applications and clients in monorepo for easier CI checks, code sharing, etc.
• We have all services completely dockerized for local development. We deploy builds to a hosted Kubernetes cluster in AWS with a single click on the Argo CD several times a day.
• Each MR can be deployed on a separate cluster for one-button testing in the CI, so we don't argue about a test environment.
• We have set up a lot of checks in GitLab CI (PHPStan, PHP_CodeSniffer, PHPUnit, lint, editorconfig-check, migration check, security scans, renovate-bot).
• In addition to static analysis, we also do a two-round review and the operation is also verified by the QA team and E2E cypress tests.
• We have more than 15 000 database integration tests with the thoughtful creation of independent datasets for each test, ie no shared data that breaks forever.
• We directly automate the agreed coding-rules, so we have already written dozens of our own phpstan rules and coding-standard sniffs.
• We think about concurrence and design the application to withstand race conditions, which is not exceptional in a warehouse environment.
• The application is supported by DataDog, Sentry, and Opsgenie.
• Our database has grown to terabyte size, so even the optimization of SQL queries is becoming the daily bread of all of us.
• We deal with HA, failover, and autoscaling, almost no service runs for us only once.
• Having experienced colleagues is our huge advantage.
• We automatically generate OpenApi documentation of all our REST-like endpoints.
• We open-source some of our best tools and contribute back to the OS community.
• We utilize code coverage.

If you like what we do and you are interested in our "story", we look forward to your resume, profile, story, whatever. There are no limits to creativity. Our Recruiter Dominika will contact you as soon as possible. We hope to be hearing from you soon.
