At
Q-tech
, we’re looking for a
Senior Java Engineer
to join a global SaaS product that’s scaling fast and moving into a more mature, reliability‑focused phase.
The platform handles a high volume of data and workflows used by customers across multiple countries. The team is strengthening its foundations to ensure stability, consistency and long‑term scalability — and they’re looking for someone who can take a leading role on the Java side.
You’d become
the Java reference point
: someone who can set technical direction, build new services with
Java + Spring + PostgreSQL
, and help elevate the platform’s engineering standards. There’s also some existing functionality in
Node.js
, and part of the work involves gradually moving that logic into the new Java‑based architecture.
This isn’t a “ship fast and patch later” environment. Quality matters: clean architecture, solid testing, strong patterns, observability, and a product that needs to behave predictably for demanding clients.
What you’ll do
Design and build backend services using Java + Spring
Bring architectural vision, patterns, and best practices
Help migrate existing Node.js components into the new Java stack
Work with clean/hexagonal architecture and rich domain models
Collaborate with a senior team and a technically strong CTO
Make autonomous technical decisions that shape the platform
Requirements
6+ years of experience working with
Java
in complex or high‑reliability environments
Strong expertise with
Spring
and the ability to design services from scratch
PostgreSQL experience is a must
(data modelling, performance, migrations, consistency)
Solid understanding of
clean/hexagonal architecture
, domain‑driven thinking and tactical patterns
Strong testing mindset and familiarity with CI/CD and engineering best practices
Ability to review, challenge and elevate the team’s technical decisions
Experience working with existing codebases and migrating functionality is a plus (some parts currently in
Node. xqbhyrx js
)
Autonomy to make technical decisions without constant oversight
Good communication skills and a collaborative mindset
Based in Spain (remote)
Experience collaborating with distributed and multicultural teams
What the role offers
Become the go‑to Java expert in the company
Build critical components from scratch
A real technical challenge with direct product impact
A stable environment focused on doing things properly
Remote work from anywhere in Spain + optional offices in several cities
#J-18808-Ljbffr
Hay opciones de teletrabajo/trabajo desde casa disponibles para este puesto.
