> Senior Platform & DevEx engineer building internal tools, reusable patterns, and architectural improvements using Nest.js, React, TypeScript, Kubernetes, and Kafka to accelerate engineering velocity, reduce friction, and mentor teams. Requires 8+ years experience in platform/infrastructure roles with strong mentorship track record.

## Job Description

## 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.

## Requirements
- 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 shared components, patterns, and tools you’ve built.
- Knowledge Distribution: The broader engineering team demonstrates increased proficiency in our core stack (Nest.js, React, Kafka) through your mentorship.

## Nice-to-Haves
- Proven expertise with AWS services including MSK, RDS, EKS, S3, and Lambda.
- Strong background in Redshift, encompassing schema design, ETL pipeline management, and query optimization.
- Practical experience using Infrastructure-as-Code (IaC) tools like Terraform for managing large-scale cloud environments.
- Hands-on experience with Redis and implementing distributed system caching strategies to resolve bottlenecks in high-throughput applications.
- Proficient in Python, including libraries like Celery and SQLAlchemy.
- Familiarity with serverless computing approaches.

## Benefits
- Health Care Plan (Medical, Dental & Vision)
- Retirement Plan (401k, IRA)
- Life Insurance
- Flexible Vacation
- Work From Home
- Wellness Resources
