Fullstack developer (Kotlin+React)

We are looking for a Fullstack developer (Kotlin+React) to join a regulated, high-stakes global tech ecosystem and drive the delivery of critical enterprise infrastructure.

Your core mission will be split between supporting a vital infrastructure observability workstream and taking ownership of a new, business-critical internal operations application. This system serves as a zero-buffer, hard go-live dependency for cutting over a massive, multi-year platform to the cloud. If you are a highly autonomous engineer who thrives on complex state management, robust backend integrations, and production-grade cloud deployments, we want to hear from you.

Responsibilities:

• End-to-End Application Ownership: Design, build, and deliver a production-grade operational administration interface, enabling operators to manage complex lifecycle data components.

• Access Control & Security: Implement frontend Role-Based Access Control (RBAC) with complex user rights management, ensuring tailored role-based rendering and access control per user type (admin, operator, read-only).

• Backend Integration & Feature Development: Write, modify, and extend clean backend code in Kotlin and Java to build robust data validation pipelines and integrate with core data services.

• Cloud Infrastructure & Deployment: Provision, deploy, and manage containerized applications within Google Cloud Platform (GCP) utilizing Kubernetes (GKE), Cloud Run, and Terraform.

• Observability & Scripting: Develop, integrate, and maintain Python monitoring and alerting scripts to create robust dashboards, manage technical metrics, and support test tooling frameworks.

• Quality Assurance & Testing: Implement rigorous unit and integration testing workflows with exceptionally high code coverage to meet strict, formal quality sign-off standards.

• Codebase Navigation & Autonomy: Rapidly onboard into a large, complex legacy platform, independently resolving technical blockers and owning your deliverables with minimal supervision.

Min requirements:

• Experience: 3 to 5 years of professional software engineering experience, including a minimum of 2 years building complex frontend applications in production (business tools, internal platforms, or financial applications preferred).

• Frontend Expertise: Solid Mid-to-Senior level proficiency in React and TypeScript, with a proven track record of handling complex state management (Redux or Context API) and implementing frontend RBAC.

• JVM Backend Skills: Practical experience (at least 1 year) with Kotlin or another JVM language, alongside the ability to read, debug, and modify existing Java codebases.

• GCP Production Experience: 1 to 2 years of hands-on experience with Google Cloud Platform, specifically utilizing GKE (Kubernetes), Cloud Run, and infrastructure provisioning via Terraform.

• Data & Workflow Automation: Strong SQL skills with the ability to query complex data models, coupled with practical experience orchestrating workflows via Apache Airflow.

• Crucial Non-Technical Skills: Extreme technical autonomy, rapid onboarding skills into unfamiliar codebases, and fluent written English for async communication and peer reviews.

• Process Alignment: Comfort working within a highly regulated corporate framework where every deliverable undergoes strict pull request workflows and formal peer sign-off.

Would be a plus:

• Domain Knowledge: A strong background in financial services, fintech, investment banking, or handling complex reference data layers.

• Advanced JVM Ecosystem: Deep understanding of modern Spring or Ktor architectural patterns.

• Data Storage Frameworks: Understanding of Google Cloud Bigtable architectures and how massive data layers are stored and read.

• Low-Level Code Awareness: Ability to read and understand existing C++ code within a legacy system context.

• Advanced Streaming: Familiarity with real-time data streaming architectures using tools like Apache Kafka or distributed risk batches.

We offer:

• Opportunity to work on bleeding-edge projects

• Work with a highly motivated and dedicated team

• Competitive salary

• Flexible schedule

• Benefits package - medical insurance, sports

• Corporate social events

• Professional development opportunities

• Well-equipped office
