Description
We're looking for a Middle+ Software Engineer - Java/Kotlin to join one of our teams: Identity or Communication Platform
As a Software Engineer, you’ll participate in building and maintaining backend services using Kotlin, as well as designing, building, and maintaining scalable backend services. You’ll help with optimization of existing systems to improve performance and reliability.
We're still in the early stages of our growth, so you’ll be able to take real ownership, shape key features, direct impact in production.
Almost everything else depends on this domain working correctly, which makes the job both high-impact and genuinely hard: dozens of internal teams rely on us, requests may require upfront analysis and discovery, and a task that seems straightforward on paper can unveil fascinating architectural challenges once you dive in.
It's the kind of environment where priorities shift and incidents happen - we are looking for someone who can adapt quickly to changing contexts and confidently design solutions, rather than waiting for a fully-scoped plan.
Challenges that await you:
- Work within our authorization domain, getting hands-on with OAuth2 flows and the AWS infrastructure behind them
- Handle integrations and feature development for internal consumer teams
- Clarify requirements with stakeholders, and design the solution
- Participate in incident response and on-call rotations when things break, to keep our infrastructure robust
- Build solid, high-quality solutions efficiently in a fast-paced environment
- Launch new platform initiatives from the ground up as our ecosystem evolves
What makes you a great fit:
- Minimum of 3 years of experience in a similar position
- Strong knowledge of one of the JVM languages (Java, Kotlin). Currently, we are using Kotlin, and familiarity with it will be an advantage.
- You have worked with Micronaut, PostgreSQL, Redis, Kafka
- If you're not familiar with Micronaut but work with Spring and its ecosystem — we're looking for you too
- Comfortable with ambiguity: you can take a vaguely described problem, figure out what's actually being asked, and design a reasonable solution yourself
- Prior experience in a platform team (rather than pure product development) or with critical high load products— is a strong green flag
- B1 or higher English level for effective communication with an international team
Bonus:
- Experience leading a non-trivial refactor, spotting architectural problems early, or designing systems in conditions of real uncertainty
- An interest in eventually working with Go is also a plus
Our technology stack:
Kotlin 2.2 • GraalVM • Micronaut (DI, gRPC) • JOOQ + Liquibase • PostgreSQL • Redis • Kafka • AWS • Grafana + VictoriaMetrics + Micrometer
Our ways of working:
- Innovative Spirit: A commitment to creativity and groundbreaking solutions
- Honest Feedback: valuing open, transparent communication
- Supportive Team: a strong, collaborative community
- Celebrating Achievements: recognizing our wins together
- High-Tech Environment: a team full of smart and revolutionary people who date to challenge the status quo of incumbent finance
Our benefits:
- Relocation support to Serbia, Cyprus, Georgia or Kazakhstan with full visa & permit support to the employee and family
- Flexible work from one of our offices or remote
- Healthcare Coverage
- Education Budget: Language lessons, professional training and certifications
- Wellness Budget: Mental health and fitness activity reimbursements
- Vacation policy: 20 days of annual leave and paid sick leave
