Job Description

About the RoleWe are looking for two Senior Software Engineers who are truly AI-first—engineers with strong software architecture fundamentals who know how to effectively use modern AI tools (LLMs, RAG, agentic workflows) to build real, production-ready systems.

You’ll operate as a SWAT-style engineering team, jumping into high-priority AI initiatives, unblocking stalled projects or POCs, and driving new AI-powered products from concept through delivery. This role works closely with VP-level leadership and senior stakeholders, helping set the standard for AI-enhanced engineering across the organization.

What You’ll Do

  • Design and build end-to-end AI-enabled applications, including backend services, APIs, and front-end interfaces

  • Apply LLMs, RAG pipelines, and agentic patterns to solve real business problems—not just prototypes

  • Own the full SDLC: discovery, design, development, testing, deployment, and observability

  • Assess and stabilize struggling AI initiatives by identifying technical, data, or product gaps and executing clear recovery plans

  • Design scalable, secure AWS architectures using services such as Lambda, ECS/EKS, API Gateway, S3, DynamoDB/RDS, event-driven systems, and Bedrock/OpenAI integrations

  • Establish best practices for AI development, including prompt and version management, evaluation, monitoring, safety, and cost control

  • Collaborate closely with product, data, and leadership teams; communicate tradeoffs and iterate quickly based on feedback

  • Mentor engineers on modern software engineering and AI development practices

What We’re Looking For

  • 7+ years of professional software engineering experience with strong full-stack capability

  • Hands-on experience building AI-powered applications using LLM platforms such as OpenAI, Anthropic, or AWS Bedrock

  • Experience implementing RAG systems, including embeddings, vector stores, and retrieval pipelines

  • Familiarity with agentic or orchestration frameworks such as LangChain, LangGraph, or custom solutions

  • Strong AWS experience designing, deploying, and operating production workloads

  • Proficiency in modern languages and frameworks such as TypeScript/Node.js, Python, Java, or Go, and front-end frameworks like React

  • Deep understanding of software architecture, CI/CD, testing, observability, and security best practices

  • Demonstrated ability to use AI to accelerate development while maintaining engineering rigor and code quality

  • Strong communication skills and comfort working directly with senior leadership and stakeholders

  • Ability to thrive in fast-moving, ambiguous environments

Nice to Have

  • Experience in media, streaming, or advertising technology

  • Previous work on tiger teams, SWAT teams, or innovation initiatives focused on accelerating or rescuing complex projects

  • Familiarity with data platforms such as Snowflake, Redshift, or Athena
