• Lead architecture discussions and make pragmatic technical decisions that balance delivery speed, reliability, and long-term maintainability.
• Use AI-assisted development tools (e.g. Claude Code, Cursor, GitHub Copilot) as a core part of your workflow to accelerate implementation, testing, and debugging, while owning the correctness and quality of everything you ship.
• Help define how the team uses AI tooling effectively and safely, including review standards for AI-generated code.
• Mentor other engineers through code review, pairing, and design feedback.
• Collaborate with product owners and the QA team to scope work, clarify requirements, and deliver clean, performant, maintainable code.
• Participate in biweekly planning, code reviews, and release planning, and drive technical planning for larger initiatives.
• Improve deployment pipelines, build tooling, and monitoring/debugging in staging and production.
• Write and champion unit and integration tests to maintain application quality across the stack.
• Participate in on-call rotations, lead incident response when needed, and drive postmortem reviews to meaningful follow-through.

• 5+ years of professional software development experience, including ownership of production systems.
• Strong proficiency in JavaScript/TypeScript and modern front-end frameworks such as React and Angular.
• Deep experience building and maintaining server-side applications in Java.
• Hands-on experience using AI coding assistants (e.g. Claude Code, Cursor, GitHub Copilot) as a regular part of your development workflow, including generating and refactoring code, writing tests, and debugging, while validating the output and owning its correctness.
• Experience with Docker and containerized application development.
• Strong knowledge of SDLC and DevOps best practices, with a track record of improving them.
• Solid understanding of RESTful APIs, JSON, and HTTP microservice architecture, including designing APIs others depend on.
• Comfortable with Git-based workflows, debugging across the stack, and shell scripting.
• Demonstrated ability to mentor engineers and lead technical discussions.
• A willingness to learn, grow, and contribute in a collaborative remote team environment.

• Familiarity with telecom or CPaaS systems (SMS, SIP, voice calling, etc.).
• Experience with relational and NoSQL databases and messaging systems like Kafka and RabbitMQ.
• Experience with observability tools like Grafana, Prometheus, and ELK.
