Job Description

The Software Engineer (Java) at BCL3 designs, develops, and evolves backend services that support core product capabilities. The role focuses on delivering production-grade features that may span multiple services, with attention to correctness, scalability, and maintainability in distributed systems.

At this level, the engineer works autonomously within established technical direction, owning components or services end to end from a technical perspective. The role requires independent problem solving, sound engineering judgment, and accountability for design decisions and code quality in systems operating at scale.

What You'll Bring

1. Advanced Java backend development: Knowledge of Java language features, concurrency constructs, and backend frameworks used to build scalable services.
2. Large scale Distributed service architectures: Understanding of multi-service architectures, inter-service communication patterns, and data flow across distributed systems.
3. Cloud-native platforms: Knowledge of building and running services on cloud platforms such as GCP, AWS, Azure, OCI, or equivalent, with GCP preferred.
4. Data persistence at scale: Knowledge of databases and data stores (SQL and NoSQL) handling large data volumes, including performance characteristics and schema evolution.

5. Software development lifecycle: Understanding of requirements breakdown, design, implementation, testing, code review, deployment and supportability of owned features within a controlled SDLC.

    

What You'll Do

1. Software development lifecycle execution: Owns the delivery of assigned features through cross discipline collaboration, requirements analysis, design, implementation, testing, code review, deployment readiness and supportability within established SDLC processes.
2. JAVA feature implementation: Implements well-defined features and enhancements spanning multiple services in Java with correct logic, tests (unit, integration, contract) ensuring backward compatibility and adherence to existing design patterns.
3. Cloud-native service development: Builds and operates Java services using cloud-native deployment and runtime patterns aligned with supported platforms, balancing cost, performance and scale.
4. Database interaction: Designs and implements data access logic, writes efficient queries, and safely evolves schemas within defined constraints.

5. Scalability-focused development: Implements solutions that handle high concurrency and large data volumes through appropriate use of concurrency, caching, service boundaries, and horizontal and vertical scaling strategies.

    

What We Offer & Expect

1. The opportunity to work on a global, mission-critical AI platform alongside the best engineers and technologists across multiple geographies.
2. A role with real ownership and impact, building complex systems at scale in an environment that values speed, experimentation, and technical excellence.
3. A highly attractive benefits package, including competitive cash compensation, an equity award aligned with long-term value creation, and comprehensive health insurance for employees and their families.
4. A modern, comfortable office in central Lviv, with an expectation of working from the office three (3) days per week, reflecting our belief in strong in-person collaboration, while remaining flexible to accommodate occasional personal circumstances that may require working from home.
5. A generous time-off policy of 30 days annually, plus public holidays and sick leave, recognising the importance of sustained high performance.

About Our Process

Our selection process is designed to rigorously assess a candidate’s depth of technical knowledge, problem-solving ability, and alignment with Behavox’s mission and core values.

As part of the process, candidates will first participate in a series of interviews focused on evaluating their technical expertise and engineering judgment. Candidates who successfully progress through these interviews will then be invited to complete a live technical exercise with a group of Behavox engineers and engineering managers.

The purpose of this live technical assessment is to validate the candidate’s stated technical competencies and assess their ability to solve complex problems with speed, accuracy, and sound engineering judgment. Note that whenever possible, we aim to conduct interviews in person at our offices.

We recognise and respect the time candidates invest in this process. In return, Behavox commits significant time and resources to ensure that those who join us have the capability, judgment, and alignment required to operate at the speed and level of complexity our work demands. We value efficiency and clarity on both sides; if at any point we determine that a candidate is not a fit, we reserve the right to immediately conclude the interview or the technical assessment.

Please note the following:

• A core objective of the process is to objectively assess individual knowledge and competencies. The use of AI tools or external assistance during live interviews or technical exercises is strictly prohibited (unless explicitly instructed otherwise) and will result in immediate disqualification.
• Interviews and technical sessions may be recorded for internal review to support fairness, consistency, and collaborative decision-making within the hiring team.

Our Mission and Vision

At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world.

About the Team and Role

We’re looking for a Kotlin Engineer to join our Finance Engineering team, which builds the finance system. It's essentially a highly powerful calculator that helps businesses run smoothly. The goal is simple: ensure that every dollar merchants and Solidgate earn ends up in their accounts correctly and on time.

We process over 18 million payments every month, generating fees based on each individual's specific settings. This affects automated payouts and financial reports.

Why it may be your next big move

Impactful work. Build a mission-critical platform that directly affects the products you use every day. We’re defining what future Solidgate financial contracts will look like.

Collaboration with experts. Work alongside engineers who built systems at Amazon, Revolut, Wix, and other world-class products.

Solve complex challenges. Design solutions for sophisticated financial logic while optimizing for reliability, observability, throughput, and scalability.

Autonomy & ownership. Own your work end-to-end — from design to deployment — and see the direct business impact of your decisions.

AI-assisted engineering: We invest in developer productivity by fully covering tools like GitHub Copilot, Windsurf/Cursor, and Coderabbit. You’ll write less boilerplate, ship faster, and focus on solving real problems — not fighting with repetitive code.

Why is it the perfect time to join?

We’re building a next-generation financial system from scratch — not refactoring legacy code.

We’re standardizing fee calculation logic, making configuration transparent and modular, and laying the groundwork for new financial modules such as pricing, billing, ledger, and more.
