Senior Java Developer v Praha, Česko - Jobeax

Senior Java Developer v Praha, Česko is listed on Jobeax. Browse 80,000+ vacancies available.

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.

About us:

Our platform is a solution for the entire process, from the warehousing of goods to the shipping of prepared packages to all corners of the world.
We have 1000+ clients, which are small and medium e-shops, mostly in the US
In the high season, we’re peaking ~100k orders per day

Our Tech stack:

Java 22
Spring ecosystem
Docker
Kubernetes (AWS EKS)
Hibernate
PostgreSQL
RabbitMQ
REST APIs
Very high bar for quality

What does it look like, and what are we proud of?

What does it look like here, and what are we 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 a 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 in the Argo CD several times a day.
With a single click in the CI, each MR can be deployed on a separate dev cluster for E2E and manual testing, so we don't have to compete with a single shared test environment.
We have a strict static-analysis setup with a lot of checks in GitLab CI (Checkstyle, SpotBugs, ErrorProne, NullAway, other linters, security scans, renovate-bot).
In addition to the static analysis, we also do two-round code reviews and the functionality is verified by the QA team and E2E Cypress tests.
We have 10k+ database integration tests with the thoughtful creation of independent datasets for each test - so no shared data that constantly breaks.
We automate the agreed-upon coding rules , to let the machines do the boring parts.
We consider concurrency and design the application to withstand race conditions, which is not uncommon in warehousing systems.
We’re using DataDog, Sentry, and Opsgenie for observability, monitoring, and support.
Our database has grown to several terabytes, so every SQL has to be optimized .
Everything runs in HA, with failovers and autoscaling.
Systems automatically generate documentation of all our APIs from code.
A lot of experienced colleagues to learn from.
Our tooling and codebase is well-compatible with modern AI agents like Claude Code.
