Leverage state-of-the-art AI developer tools (e.g., Claude Code, GitHub Copilot, LLM reasoning models) to accelerate context gathering, boilerplating, test generation, and code refactoring.
Build and maintain microservices that communicate via well-defined APIs, ensuring service modularity and scalability.
Implement robust unit tests, integration tests, and end-to-end tests to ensure high-quality code. Work towards achieving high test coverage and adopting test-driven development (TDD) where applicable.

Conduct and participate in code reviews, ensuring adherence to coding standards, best practices, maintainability, and critically evaluating AI-generated code outputs for security and correctness.
Participate in design sessions to help improve the overall architecture of the platform.
Work with stakeholders and product owners to understand requirements and come up with solutions.
Continuous learning: Tillster provides access to learning courses where you can beef up your skills in different areas as needed.

About You

2+ years’ experience in design and development of service-oriented Java, Python, C#, Typescript (or any modern language) applications.
Experience in designing and building microservice-based systems, ensuring high cohesion and loose coupling.
Languages: Any modern OOP language will do, but Typescript is preferred.
Comfortable integrating AI tools (e.g., Claude Code, Cursor, ChatGPT/Claude) into your daily workflow to boost engineering velocity while maintaining deep critical code validation.
Experience implementing comprehensive testing strategies including unit tests, integration tests, and end-to-end tests.
Experience with relational or NoSQL data stores.
Expertise in applying industry-standard design patterns and architectural patterns.
Ability to communicate effectively in English, with good verbal and written skills.
Experience working in an Agile environment (Scrum or Kanban), contributing to team-driven development processes.
Understanding of security best practices in software development, including OAuth, JWT, encryption, etc.
Bachelor’s degree in Computer Science (or similar) or equivalent experience.
Prior experience with AWS serverless and companion technologies like DynamoDB, SQS, etc. would be great but not required.
Strong analytical and problem-solving skills, with a mindset geared toward continuous improvement.
Comfortable working in a fast-paced, dynamic environment, with the ability to handle ambiguity and changing requirements.
