Job DescriptionOverview
We are looking for a Staff Software Engineer to lead the delivery of high-throughput, large-scale transactional systems and agentic AI applications. You will serve as a technical anchor across engineering squads - setting the bar for code quality, cloud architecture, and engineering excellence while mentoring the next generation of engineers. You will report to the Sr. Principal Engineer.
Responsibilities:- Architect, build, and own services for large-scale transactional platforms - ensuring high availability, fault tolerance, and sub-second performance at millions of transactions per second.
- Lead the end-to-end design of agentic AI workflows using orchestration frameworks, such as LangGraph, AutoGen, and CrewAI. Implement these workflows using tool-calling patterns and multi-agent coordination on AWS.
- Write production-grade Python and Go services; establish language-specific idioms, patterns, and performance baselines adopted across engineering teams.
- Design and govern AWS-native infrastructure (ECS, EKS, Lambda, MSK, RDS Aurora, DynamoDB, SageMaker, or EventBridge) - ensuring solutions align with the AWS Well-Architected Framework.
- Establish engineering standards: code review practices, test coverage requirements, CI/CD pipelines, and observability instrumentation (distributed tracing, structured logging, alerting).
- Conduct and lead technical design reviews for new services, integrations, and platform changes; produce high-quality architecture decision records (ADRs) and technical specs.
- Resolve performance bottlenecks in distributed systems, including database query optimization, caching strategies, and async processing patterns.
- Guide proof-of-concept (PoC) work for new technologies and evaluate their production readiness; present recommendations to engineering leadership.
- Mentor and level up senior and mid-level engineers through structured code reviews, pairing sessions, and technical coaching.
- Contribute to on-call rotations, incident response, and post-mortem processes to guide systemic reliability improvements.
Qualifications- B.S. or M.S. degree in Computer Science, Software Engineering, or a related technical discipline
- 8+ years of professional software engineering experience, including 3+ years in a staff-level, principal, or equivalent technical leadership role.
- 4+ years of hands-on experience building and operating production services on AWS - with deep familiarity across compute (ECS/Fargate, EKS, Lambda), storage (S3, RDS, DynamoDB), messaging (SQS, Kafka), and networking (VPC, API Gateway, CloudFront).
- 2+ years of professional Python development with command of async patterns (asyncio, FastAPI, Pydantic); 2+ years of Go in production microservices.
- Demonstrated experience architecting and operating large-scale transactional systems (high-volume OLTP, event-driven architectures, distributed caches, saga/outbox patterns).
- Hands-on experience building agentic AI systems - including agent orchestration, tool/function calling, RAG pipelines, and LLM integration patterns.
- Command of relational and non-relational databases (PostgreSQL, Aurora, DynamoDB, Redis, or ElasticSearch) with experience with query optimization and schema design at scale.
- Proficiency with containerization and infrastructure-as-code (Docker, Terraform, CDK, or Helm).
- Experience with observability tooling: Datadog, OpenTelemetry, CloudWatch, or equivalents.
- Experience owning and evolving CI/CD pipelines using tools like Jenkins, GitHub Actions or Harness.
- Experience integrating async messaging systems (Kafka, SQS) and designing event-driven architectures.
- Experience mentoring engineers and driving company level improvements in engineering culture, quality, and velocity.
