About the role

Senior Software Engineer in an AI-native environment responsible for architecting and implementing AI-driven, scalable systems, integrating LLMs, knowledge graphs, and intelligent workflows into an enterprise-scale platform.

Responsibilities

  • Take end-to-end ownership of complex features and systems—from architecture and implementation to deployment and observability.
  • Design and evolve AI-native services that embed LLMs and reasoning capabilities directly into product workflows.
  • Work cross-functionally with product, design, and data teams to infuse AI-powered intelligence into the user and developer experience.
  • Drive architectural decisions that balance rapid experimentation with long-term scalability and reliability.
  • Backend First: Lead design, implementation, testing, and deployment of backend services, APIs (REST/GraphQL), and core data infrastructure that power scalable enterprise workflows.
  • Full Stack Delivery: Build user-facing features where needed, connecting frontend UI with backend systems — you’ll own the full path from browser to database.
  • Shape the Stack: Help define and evolve our architecture — from backend systems and databases to the UI frameworks and client integrations that consume them.
  • AI and Workflow Innovation: Integrate AI/LLM capabilities into backend pipelines and product logic that make ITSM smarter and easier to use.
  • Performance & Scale: Architect highly performant, secure, and scalable services for enterprise environments, with monitoring and observability in place.
  • Collaboration: Partner with designers, frontend engineers, and infrastructure teams to translate product thinking into real, high-impact solutions.
  • Developer Experience: Improve internal tooling, deployment pipelines, and best practices around CI/CD and automated testing.
  • Security & Compliance: Build with enterprise-grade security and compliance in mind (SOC 2, ISO 27001).

Qualifications

  • Experience: Strong background in backend systems and API design with real SaaS production experience; comfortable contributing across the stack.
  • Backend Languages: Proficiency in one or more modern backend languages (Python, Go, Rust, C++, etc.) and designing distributed systems.
  • Frontend Fluency: Familiar with modern frontend frameworks (React, Vue, Angular) and comfortable building or iterating on UI components that interface with your backend.
  • Databases & Storage: Strong hands-on experience with NoSQL and (ideally) graph or databases.
  • Cloud & DevOps: Experience with cloud platforms (AWS/GCP/Azure), containerization (Docker/Kubernetes), and infrastructure as code (Terraform).
  • Problem Solving Mindset: Pragmatic, product-driven engineer who thrives in high-velocity startup environments and can balance backend complexity with UI quality.
  • Bonus: Experience integrating AI/LLM features or working with enterprise workflow systems.
