Job summary

CINC is seeking a Staff Full-Stack Software Engineer to design and deliver scalable applications across the stack, from backend services to frontend interfaces. You will help set technical direction and own large, cross-team initiatives in a fast-moving environment.

You will mentor engineers, drive architecture decisions, and work with product and AI teams to deliver robust, user-centered features that scale across a remote-first organization.

Qualifications

• 7+ years of software engineering experience building production web applications or SaaS products.
• Deep expertise in backend architecture, including monolith decomposition, microservice principles, and API design best practices.
• Proven record of designing and maintaining RESTful or GraphQL APIs with clear contracts and documentation at scale.
• Working knowledge of modern DevOps practices: CI/CD pipelines, observability, and containerized deployments.
• Familiarity with cloud environments such as AWS, GCP, or Azure.
• Solid experience with automated testing frameworks and test-driven development (TDD).
• Experience making and documenting architectural decisions (such as ADRs) that balance scalability, cost, and maintainability.

Responsibilities

• Design, build, and maintain high-quality web applications using TypeScript, Node.js, and frameworks such as React, Next.js, or NestJS.
• Drive the evolution of CINC's architecture from monolith to modular microservices, applying sound system design and domain-driven thinking and defining service boundaries across teams.
• Develop and consume RESTful and GraphQL APIs with a strong grasp of service boundaries, contract design, and versioning, and establish API standards that other teams adopt.
• Implement event-driven and message-based integrations that improve scalability, resilience, and decoupling.
• Apply modern engineering practices, including automated testing, CI/CD, and continuous delivery.
• Partner with design and product to turn complex requirements into simple, usable features.
• Practice code review, pair programming, and iterative delivery in line with XP values.
• Bring Cephai-powered capabilities into user-facing features by integrating APIs and shared AI services where they help people do the work.
• Mentor and grow senior and mid-level engineers, raising the bar on system design, testing, and clean code across teams.
• Lead technical discussions on architecture, reliability, and performance, and influence decisions that affect multiple teams.
• Lead technical design and delivery of cross-team initiatives, breaking ambiguous problems into clear plans and aligning stakeholders on trade-offs.
