Senior Software Engineer, Platform & Developer Experience

Worth AI, a leader in the computer software industry, is looking for a Senior Engineer to join our Platform team with a singular mission: to make our engineering organization faster, more reliable, and more joyful. In this role, you won't just be building features for end-users; you will be building the "Product for the Engineers." You will act as a force multiplier by identifying friction in the development lifecycle, architecting shared patterns, and unblocking technical debt that slows the team down. You are part architect, part investigator, and part educator. ### Responsibilities - Conduct regular interviews with engineering teams to find pain points in their daily workflows and prioritize the creation of tools or architectural changes to eliminate them. - Design and implement reusable patterns using Nest.js, React.js, and TypeScript that enable other engineers to ship high-quality, performant services and interfaces by default. - Take ownership of systemic performance issues, such as optimizing slow PostgreSQL queries or refining Kafka producer/consumer patterns to ensure reliable message delivery. - Own and evolve our Kubernetes and ArgoCD configurations to ensure seamless, automated, and safe deployments across the organization. - Lead nebulous, cross-team technical challenges such as re-architecting shared libraries or evolving our service-to-service communication and drive them to a concrete resolution. - Identify "sticky" or overly complex codebases and lead the effort to refactor them into maintainable, testable, and modern modules. - Actively mentor and coach engineers across the organization, helping them level up their technical skills and understanding of our core architecture. - Research, prototype, and roll out new internal tools, libraries, or frameworks that improve CI/CD, local development, or system observability. - Introduce new frameworks or architectural shifts to the team and provide the documentation, workshops, and 1:1 support needed for successful adoption. - Lead by example in code reviews, coaching others on maintainable design, testing strategies, and system-level risk mitigation. - Communicate complex technical trade-offs effectively across functions, using empathy and self-awareness to handle conflict and align differing perspectives. **Technology Stack** - Languages & Runtimes: Node.js, TypeScript - Frameworks: Nest.js, React.js - Data & Messaging: PostgreSQL, Kafka, Redis, Redshift - Infrastructure & Orchestration: Kubernetes, ArgoCD - Monitoring: DataDog - 8+ years of experience in software engineering with a proven track record of leading teams and providing technical direction. - Deep passion for mentorship with a history of developing the technical careers of associate and intermediate engineers. - Prior experience specifically within Platform, Infrastructure, or Developer Experience (DevEx) teams. - Deep professional expertise in the Node.js/TypeScript ecosystem, including experience scaling Nest.js backends and React.js frontends. - Hands-on experience managing containerized workloads using Kubernetes and ArgoCD. - Strong proficiency in PostgreSQL (query optimization and schema design) and Kafka (event-driven architecture). - Proven ability to "unroll" complex legacy code and replace it with scalable, maintainable architecture. - Experience navigating high-ambiguity environments and translating vague technical frustrations into prioritized roadmaps. - Demonstrated ability to build psychological safety and trust within a team while raising the engineering quality bar. ### Success Metrics - DORA Metrics Improvement: Drive measurable improvements in Deployment Frequency, Lead Time for Changes, Change Failure Rate, and Mean Time to Recovery (MTTR). - System Latency: Successfully optimize core services to meet strict P90 and P99 latency targets, specifically targeting slow endpoints and database bottlenecks. - Developer Velocity: Engineers ship code faster and more confidently due to the s…
