Behavox is a cloud-native AI company providing an integrated controls platform for global banks, asset managers, hedge funds, private equity firms, insurance businesses, and commodity firms. The platform unifies communications and trade surveillance, compliant archiving, policy management as well as front-office analytics on a single, AI-native technology stack, delivered as a globally scalable SaaS-based cloud service.

At Behavox, our engineering culture is built around speed, experimentation, and technical excellence, following agile principles and rapid iteration. We constantly test and adopt the latest cloud technologies and AI tooling, optimising for fast feedback loops and execution. We look for people who can move fast, challenge conventional wisdom, and who want to work at the frontier of modern AI, SaaS platforms, and distributed systems.

Behavox is a high-performance organisation with a strong bias toward delivery, ownership, and responsibility. We commit, and we execute. We are building systems that are complex, mission-critical, and global in scale; systems that many consider too large or too difficult. To do that, we seek the smartest, most technically capable engineers and technologists who take end-to-end responsibility and want to win by building what others cannot.

Founded in 2014 and backed by SoftBank Vision Fund, Behavox is headquartered in London, with offices worldwide, including New York City, Montreal, Seattle, Singapore, and Tokyo.

The Software Engineer (Angular) at BCL3 designs, develops, and evolves frontend applications that support core product capabilities. The role focuses on delivering production-grade user-facing features that may span multiple frontend modules or applications, with attention to correctness, performance, scalability, and maintainability.

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

1. Advanced Angular application development: Knowledge of Angular, modern JavaScript and TypeScript, component architecture, state management, and frontend frameworks used to build scalable web applications.
2. Large-scale frontend architectures: Understanding of modular frontend architectures, shared component systems, application composition, and interaction patterns across complex user interfaces.
3. Cloud-hosted frontend delivery: Knowledge of deploying and running Angular applications using cloud-based build, hosting, and content delivery platforms, including environment configuration, access control and runtime behavior.
4. Frontend data integration: Knowledge of integrating frontend applications with backend services using APIs, including data modeling, error handling, and performance considerations.
5. Software development lifecycle concepts — Understanding of lifecycle stages, dependencies, and constraints that influence how frontend features are designed, delivered, tested, and supported within a controlled SDLC.

1. Software development lifecycle execution: Owns the delivery of assigned frontend features through cross discipline collaboration, requirements analysis, design, implementation, testing, code review, deployment readiness, and supportability within established SDLC processes.
2. Angular feature implementation: Implements well-defined frontend features and enhancements using Angular and TypeScript, ensuring correct behavior, test coverage, and adherence to established design patterns.
3. Unit, integration, functional and contract testing: Designs and implements unit, integration, functional and contract tests for frontend features, validating user workflows, API interactions, error handling, and edge cases to ensure production-ready behavior and prevent regressions.
4. API-driven frontend integration: Designs and implements frontend data flows using backend APIs, ensuring correct contracts, efficient data handling, and resilient, responsive and usable user experiences.
5. Scalability-focused frontend development: Implements frontend solutions that handle high user concurrency and complex UI states through efficient rendering, state management, caching strategies, and performance optimization techniques.

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 five (5) 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.

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.
