Join a Company that Empowers you to Build your Future We are seeking a Senior Software Engineer to serve as a technical leader on a domain product team delivering high-impact, full-stack business applications and ServiceNow solutions. Our product teams own their systems end-to-end in a self-service model built on capabilities from central platform teams — IDP golden-path templates, shared CI/CD, and reusable infrastructure modules. You will drive architecture within your product domain, champion effective use of platform capabilities, and act as a key feedback partner to platform teams — while mentoring engineers and raising the technical bar. Your Responsibilities on the Team  Lead the architecture, design, and implementation of full-stack systems using TypeScript/React and Go. Own complex ServiceNow development initiatives, including custom applications and enterprise integrations within your domain. Drive your team's adoption of self-service platform capabilities — IDP templates (e.g., Backstage), shared CI/CD pipelines, and Terraform modules — and establish team standards on top of them. Partner with central platform teams: provide feedback, influence roadmaps, and contribute improvements to shared templates and modules where appropriate. Lead the development of agentic and AI product capabilities — AI agents, MCP servers, and LLM-powered features — ideally leveraging AWS Bedrock. Own production readiness for your team's services: observability, reliability, security, and performance. Mentor and develop engineers through design reviews, pairing, and technical guidance. Partner with product stakeholders to translate business needs into scalable technical solutions.

Bachelor's degree in Computer Science, Engineering, or related field, or equivalent practical experience. 5+ years of professional software development experience, including ownership of production systems at scale. Expert-level proficiency in TypeScript and React, and strong backend experience with Go. Deep understanding of system design, API architecture, security, and performance optimization. Proven success operating in a DevOps/self-service environment where product teams own their infrastructure and delivery pipelines. Demonstrated technical leadership: driving projects end-to-end, setting standards, and mentoring engineers. Excellent communication skills with both technical and non-technical audiences.

Proven ServiceNow development and integration experience — highly preferred. Deep CI/CD expertise (GitHub Actions or similar) — highly preferred. Strong infrastructure-as-code expertise (Terraform or similar) — highly preferred. Experience self-serving through internal developer portals such as Backstage (golden paths, software templates, service catalogs). Production experience building agentic/AI systems (AI agents, MCP servers, LLM applications); hands-on AWS Bedrock experience is a strong differentiator.
