Overview

As a Tech Lead, you define the technical direction and architecture behind AI-driven products and services at scale. Working at the intersection of Data Science and Engineering, you lead the design and delivery of LLM-based systems that operate reliably in production.

You’ll work in a modern, cloud-native environment, building services on AWS EKS and leveraging platforms like AWS Bedrock and Google Vertex AI.

What you’ll do

• Lead the design, delivery, and operation of AI-driven services

• Architect and scale production-ready AI systems using large language models and agent frameworks

• Partner with Data Science and Engineering to turn experiments into robust, scalable systems

• Own service reliability, performance, security, and scalability

• Shape the technical roadmap by identifying improvements and surfacing risks early

How you’ll do it

• Design and evolve backend services (primarily Scala and Rust, with Python for data and model workflows)

• Build and run cloud-native systems on AWS EKS with strong practices in observability, resilience, and automation

• Work with managed LLM platforms, including:
  • AWS Bedrock (foundation models, knowledge bases, guardrails)
  • Google Vertex AI (model hosting and inference)

• Establish best practices for agent patterns (multi-turn interactions, RAG, tool use)

• Maintain high engineering standards through design reviews, testing, and CI/CD

What you’ll influence

• The technical direction of AI-powered products and platform capabilities

• Alignment across Data Science, Engineering, and Product

• Long-term scalability and maintainability of AI systems

What you bring

• Strong experience building and operating backend or platform systems in production

• Hands-on experience with LLMs, agents, and patterns like RAG and orchestration

• Proficiency in a backend/systems language (e.g. Scala or Rust)

• Experience collaborating with Data Science teams using Python

• Experience running services on AWS (Kubernetes/EKS preferred)

• Familiarity with platforms like AWS Bedrock and/or Vertex AI

• Solid system design skills (distributed systems, state, fault tolerance)

• Ability to lead technically without direct line management

Nice to have

• Experience operating AI systems under real constraints (latency, cost, reliability)

• Experience evaluating and monitoring AI systems in production

• Background in customer-facing SaaS platforms

What we offer

• Ownership of high-impact AI initiatives with real customer impact

• A modern stack: Scala, Rust, Python, AWS EKS, Bedrock, Vertex AI

• The chance to shape how AI systems are built and operated at scale

• Collaboration with experienced engineers, data scientists, and product leaders
