Do you enjoy turning complex business rules into elegant,
reliable code
?

Are you excited by the idea of shaping how mortgages and credit decisions are calculated and assessed in a modern,
cloud‑native
stack?

If you’re a
Software Engineer
focused on
Java
stack who wants to see your work directly impact real customers, this role is for you, either in Bratislava or Zilina.

Briefing

You’d be joining our Mid‑office team, the heart of our
mortgage
and
credit assessment engine
, where
calculations
,
reporting
,
valuation
and party integrations all flow through your services.

Working closely with product and other engineering teams, you’ll help design and build
REST APIs
that track and apply domain‑specific rules – from credit limits and approval policies to configuration changes – across all phases of the assessment journey.

In your day‑to‑day work, you’ll use
Java 21
and
Spring Boot 3.x
to design and build the services and
APIs
that power our
cloud‑native core banking
platform.

You’ll work on features that track and apply configuration changes to domain rules (such as credit limits and approval policies), support mortgage and credit assessments across multiple phases, and keep our Mid‑office services healthy and reliable through clear monitoring and automated tests.

You’ll be able to bring your experience, learn from colleagues, and have real ownership of how we evolve the Mid‑office platform, while seeing the impact of your work across multiple assessment phases and services.

About You

• You are a
  seasoned Software Engineer
  with solid experience building back‑end services in Java (Java 17+, ideally Java 21).
• You have hands‑on experience with
  Spring Boot
  (3.x preferred), and you’re comfortable designing and implementing
  REST APIs
  that are simple to use and easy to maintain.
• You write
  clean,
  testable
  code
  and have experience with
  unit
  and
  integration testing
  .
• You understand how to design for correctness and performance without over‑engineering.
• You are comfortable with more
  robust systems
  and curious about potential improvements in all the aspects of your work.

Why this job is exciting

We're changing how we build. We're moving from teams where each developer owns a slice of an epic to builders who own the whole thing. A builder takes an idea and ships it: designed, implemented, evaluated, deployed. One person, full ownership, from first commit to production.

Agents made this possible. At Innovatrics, engineers develop with AI agents as the default way of working: you direct the work, the agents produce much of the code, and you own the result. Claude Code is our standard. The craft is judgment: knowing what to delegate, what to verify, what to build by hand, and how to prove the result is correct.

That last part is the heart of this job. We build biometric identity systems used by governments, banks, and security agencies: face recognition, fingerprint matching, identity verification at airports, at borders, in banking apps. This domain is regulated and adversarial. People probe our systems to defeat them. So we ship what we can stand behind, and proving correctness is part of the craft here, with the same weight as writing the code.

What you'll be doing

• Owning features end to end: design, implementation, evaluation, deployment. Done means running in production.
• Directing AI agents through most of the build, then verifying the output as if you wrote every line yourself. You own agent output the same way you own your own code.
• Writing evals as part of delivery, so correctness is demonstrated rather than assumed.
• Improving the shared machinery: when an agent makes the same mistake twice, the context, prompt patterns, or harness gets fixed so it can't recur, for the whole team.
• Making deliberate calls on when AI is the wrong tool: security-sensitive code, novel biometric algorithms, deep-system work.
• Working across the stack your product needs, going wherever the problem is rather than waiting at a layer boundary.
• Collaborating with product and other engineers when you need input, without waiting for permission to move.

What we're looking for

We hire builders at 2 levels. The core is the same at both; the scope of ownership differs.

• A developer who has shipped real things to real users, and can walk us through what broke and what they learned.
• Comfort across more than one language or stack, with genuine depth in at least one. Builders range wide; the best ones also go deep where their product demands it.
• Hands-on experience developing with AI agents (Claude Code or comparable), and a clear-eyed view of what they get wrong: plausible-but-broken logic, invented packages, missed edge cases.
• The habit of verification: you can say how you know a piece of work is correct, whether you wrote it or an agent did.
• A bias toward done over perfect, with correctness intact.
• Comfort with ambiguity: you can take a rough brief, scope it, and figure out the rest.

As a mid-level builder, on top of that:

• You own complex work autonomously: you take an Epic-sized requirement, structure it, and deliver it with light guidance.
• You write evals for your own work and invest in the team's shared agent setup beyond your own productivity.

As a senior builder, on top of that:

• You take a high-impact requirement and turn it into a shipped solution across team boundaries.
• You help define the team's agent strategy: which problems get agents, which get humans, which get pairs.
• You own the team's eval discipline and build the harnesses, context files, and agent skills the team depends on.
• You articulate taste: you can explain why one design beats another, spot hallucinated code in review, and say no with reasons.
• You develop the engineers around you, deliberately, so they form real skills while agents do the obvious work.

Good to have

• Experience with Java, Python, Go, C++, TypeScript, Kotlin, or Swift (different teams use different sets).
• Familiarity with biometrics, computer vision, or identity verification.
• Experience building evaluation pipelines, test harnesses, or CI quality gates.
• Cloud infrastructure (AWS, Azure, GCP) or container orchestration (Kubernetes, Docker).

These roles map to the Software Engineer and Senior Software Engineer bands of our career framework. We'll calibrate level together during the process, based on the scope of ownership you've actually carried. The framework runs to Distinguished Principal, and the growth path is real.

What we offer

• Direct impact: your work ships to global customers and gets used in the field.
• A culture that trusts you to own your work.
• Hybrid work from our Bratislava office, with flexibility on days and hours.
• Competitive salary benchmarked to market, reviewed annually.
• Hardware of your choice and a full AI tooling budget. We pay for the tokens; you bring the judgment.
• A team that takes its craft seriously and is honest about what isn't working.

Compensation

At Innovatrics, we offer highly competitive salaries because we value top talent who share our values and goals. Compensation is determined based on your level, skills, experience, qualifications, and location.

Beyond base pay, we provide an attractive benefits package.
