Job Title

AI - Software Engineering - Fellow I

About your role :

The AI - Software Engineering - Fellow I will lead the engineering team building multi-tenant agentic AI platform for financial services. In addition you will own the technical strategy, delivery and production operations at scale.

What you will do:

- Own end-to-end engineering delivery of the agentic AI platform

- Set technical vision and architecture direction for a multi-tenant agentic platform built on AWS Bedrock AgentCore, Strands Agents SDK, and Cedar/AVP authorization

- Recruit, hire, and develop pillar leads and senior engineers across Identity & Access, Agent Runtime, Observability & FinOps, Catalog & Registry, and Evals & Testing

- Drive platform security posture — threat modeling for agent delegation chains, prompt injection defence, cross-tenant isolation, and regulatory compliance (SOC2, OCC, FFIEC)

- Establish engineering standards — ADRs, SDK architecture patterns, code review culture

- Build and operate the agent onboarding pipeline — enabling adjacent business teams to build, certify, and deploy agents on the platform

- Define SLOs, operational readiness criteria, and incident response processes for a banking-grade production platform

- Manage cross-pillar dependencies and technical risk — credential flows, MCP Gateway governance, audit pipeline completeness, and multi-tenant data isolation

- Partner with Security to establish pre-GA sign-off gates including penetration testing, SAST/DAST integration, and compliance certification

- Drive FinOps discipline — per-tenant cost attribution, LLM usage optimization, and infrastructure right-sizing

What you will need to have:

- 10+ years of software engineering experience, with 5+ years leading engineering teams across multiple product areas or platform pillars

- Proven track record building and shipping multi-tenant SaaS platforms — ideally in financial services, payments, or regulated industries

- Deep hands-on experience with AWS (IAM, KMS, Cognito, DynamoDB, S3, Lambda, Step Functions, ECS/EKS) and infrastructure-as-code (CDK or Terraform)

- Strong background in platform engineering — SDK design, API governance, developer experience, and internal platform adoption

- Experience with identity and authorization architectures — federation, RBAC/ABAC, credential management, tenant isolation patterns

- Demonstrated ability to recruit, develop, and retain senior engineering talent in a high-growth environment

- Experience managing AWS or cloud vendor partnerships with embedded engineering resources

- Familiarity with security and compliance in financial services — threat modeling, penetration testing, audit requirements, data residency

- Strong architectural judgment — ability to make build-vs-buy decisions, set technical direction across distributed teams, and manage technical debt

- Bachelor's degree in Computer Science, Engineering, or related field (or equivalent experience)

What would be nice to have:

- Experience with AI/ML platforms, LLM orchestration, or agentic systems.(agent frameworks, tool use, multi-turn workflows, human-in-the-loop patterns)

- Familiarity with AWS Bedrock, AgentCore, or similar managed AI services.

- Knowledge of Cedar policy language, Amazon Verified Permissions, or comparable policy engines.

- Experience with observability at scale — OpenTelemetry, distributed tracing, audit pipelines, PII redaction.

- Background in MCP (Model Context Protocol), agent-to-agent delegation, or governed tool execution.

- Experience leading platform teams through SOC2 certification, OCC examination readiness, or FFIEC compliance/

- Prior experience at a fintech, payments processor, or banking technology company.
