We are seeking a highly motivated and experienced Senior Software Engineer to join our Bruin Software Engineering Team in NYC!

ROLE AND RESPONSIBILITIES:

• Migration Leadership: Own the end-to-end rewrite of a production enterprise web application to a modern stack (NestJS, React/TypeScript, Temporal.io), executing module by module with backwards compatibility to the existing MSSQL database.
• AI-Augmented Engineering: Use Claude Code as a primary tool — directing it to generate, refactor, and validate code while applying your judgment to review output and make architectural decisions.
• Full-Stack Development: Build across backend (Javascript, Python, NestJS/Node.js), frontend (React + TypeScript), and data layers (TypeORM + Microsoft SQL Server).
• Workflow Engineering: Migrate legacy BPT-style process flows to Temporal.io, including long-running processes, human task queues, timers, and conditional logic.
• API & Integration: Design and maintain RESTful APIs with OpenAPI/Swagger documentation. Manage clean contracts between new and legacy modules during transition.
• Cloud & DevOps: Deploy and manage solutions on AWS, Azure, or GCP. Implement and maintain CI/CD pipelines, IaC, and containerised deployments (Docker, Kubernetes).
• Code Quality: Establish engineering standards for the new codebase, conduct code reviews, and write well-tested, maintainable code.
• Mentorship: Guide junior engineers and model effective, responsible use of AI-assisted development tooling.

DESIRED QUALIFICATIONS:

• Must be a strong engineer with the fundamentals and judgment to work effectively alongside AI tooling.
• 5+ years of professional software engineering with a track record of delivering production systems.
• Strong TypeScript/JavaScript and Node.js experience; NestJS or similar backend framework.
• Solid React experience building complex, data-driven web applications.
• Relational database experience and proficiency with ORM frameworks; MSSQL a strong plus.
• Cloud platform experience (AWS, Azure, or GCP) and hands-on DevOps — CI/CD, containerisation (Docker, Kubernetes).
• Comfort reading and reasoning about systems you didn’t build — legacy codebase analysis is central to this role.
• Openness to AI-assisted development tools (Claude Code, Copilot, Cursor, or similar) as a core part of your engineering workflow.
• Strong communication skills; able to articulate technical decisions to both engineering and non-technical stakeholders.

NICE TO HAVE:

• C# or other strongly-typed backend language experience.
• Data pipeline experience (Apache Airflow, Apache Flink, Kafka, or similar).
• Workflow/orchestration engine experience (Temporal.io, Conductor, or similar).
• Figma familiarity — able to work directly from design files without handoff friction.
• Experience migrating from a low-code or legacy enterprise platform.
• Certifications in AWS, Azure, GCP, or Kubernetes.
