## Job Description

## What You’ll Be Doing

- Design and build backend services supporting financial workflows and transaction processing using Java and modern JVM frameworks.
- Own features end to end — data model, service, API, and the Angular frontend that consumes them.
- Build and maintain APIs used by internal services, external integrations, and our own frontend.
- Contribute to architectural discussions and evolve service-oriented, event-driven systems.
- Improve system reliability, performance, and observability across the stack.
- Refactor and modernize legacy systems as the platform evolves.
- Troubleshoot production issues and implement long-term fixes.
- Partner with product and design to translate requirements into working, well-tested features.
- Participate in code reviews and advocate for strong engineering standards.
- Use AI-powered development tools, including Claude, to accelerate software design, implementation, testing, debugging, documentation, and code review.
- Apply strong engineering judgment when reviewing AI-generated solutions, validating them for correctness, maintainability, security, performance, and alignment with established architectural standards.
- Leverage AI to understand unfamiliar codebases, investigate defects, evaluate implementation options, and identify potential edge cases or system impacts.
- Use AI tools responsibly, ensuring that proprietary data, customer information, credentials, and other sensitive material are handled in accordance with company security policies.
- Share effective AI workflows, reusable prompts, and best practices that improve engineering productivity and quality across the team, and evaluate emerging AI development tools worth adopting.

## What You’ll Bring to the Team

- 5+ years of experience working as a backend engineer in a production environment.
- Deep experience building backend services using Java and modern JVM frameworks.
- Experience designing APIs and service-oriented systems.
- Experience working with relational databases and large datasets.
- Experience with distributed systems and event-driven architectures.
- Working proficiency with a modern reactive frontend framework (Angular preferred; Vue or React experience welcome) and TypeScript.
- Familiarity with containerized environments such as Docker and Kubernetes.
- Hands-on professional experience using AI coding assistants (Claude, Copilot, Cursor, or similar) as part of your regular workflow.
- Strong judgment about when to rely on AI tooling and when human review is essential — particularly around security, data handling, and financial workflows.
- Highly self-reliant — able to unblock yourself, make sound technical decisions independently, and lead initiatives end to end with minimal supervision.
- Strong debugging, problem-solving, and communication skills.
- Experience in regulated industries, such as financial services or cannabis, is a plus.
