Senior Software Engineer - Bruin Platform Full Stack

About the role

We are seeking a Senior Software Engineer – Full Stack to join a new Bruin Platform Modernization team in NYC.

Responsibilities

• Tech Stack Modernization: Drive Bruin's tech stack modernization in partnership with the Principal Software Architect — moving core platform components onto modern frameworks, retiring legacy patterns, and establishing the patterns the next generation of Bruin will be built on.
• Architecture & Design: Partner with the Principal Software Architect on architectural decisions across the modernization scope. Write ADRs for significant design choices, evaluate framework and infrastructure options, and contribute to platform-wide design discussions.
• Full-Stack Development: Design, build, and ship new Bruin core services and customer-facing features on the modernized stack. Build across backend, API, and data layers.
• Cross-Track Capacity: Work flexibly across the team's tracks, where additional depth or full-stack capacity is needed. Comfortable picking up work in unfamiliar parts of the codebase and ramping quickly.
• Cloud & DevOps: Build and operate services on our containerized infrastructure (Kubernetes on-premise). Establish and follow CI/CD, IaC, and deployment patterns alongside the team.
• Code Quality & Mentorship: Conduct code reviews, write well-tested maintainable code, and contribute to a high engineering bar across the team. Guide collaborating junior and mid-level engineers.

Qualifications

• Must be a strong full-stack engineer with the fundamentals and judgment to work effectively alongside AI tooling and to operate with high autonomy.
• 7+ years of professional software engineering, with significant time spent shipping production full-stack applications.
• Strong proficiency in at least two modern programming languages, with .NET and TypeScript/JavaScript (Node.js) preferred, plus working knowledge of multiple language ecosystems (e.g., Python, Go, Java).
• Solid React + TypeScript experience building complex, data-driven web applications; comfort with modern front-end tooling.
• Production experience with a modern backend framework (e.g., ASP.NET Core, NestJS, FastAPI, or similar).
• Hands-on experience designing and operating microservices and event-driven architectures, including production work with Kafka and Redis (or similar messaging and caching infrastructure).
• Relational database experience and proficiency with ORM frameworks; familiarity with MSSQL a plus given Bruin's existing data layer.
• Hands-on experience with containerized deployment (Kubernetes, Docker), and comfort with CI/CD pipelines.
• Familiarity with cloud platforms (AWS, Azure, or GCP) as adjacent experience — many of the patterns transfer to our on-premise environment.
• Comfort reading and reasoning about systems you didn't build — legacy codebase analysis and modernization are central to this role.
• Demonstrated proficiency with 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 engineering peers and non-technical stakeholders.

Desired Qualifications

• Experience building AI-powered or AI-augmented application features — chat interfaces, agent integrations, tool-use surfaces, RAG patterns, or similar.
• Workflow / orchestration engine experience (Temporal.io, Dagster, or similar).
• Previous experience contributing to a brownfield modernization.
• Experience building data-intensive applications — large-scale data pipelines, real-time analytics, high-throughput event processing, or systems where data volume and consistency are first-class design concerns.
• Search and analytics infrastructure exposure (Solr, OpenSearch, StarRocks, ClickHouse, or similar).
• Telecom, managed services, or B2B platform domain experience.
• Certifications in AWS, Azure, GCP, or Kubernetes.
