Software Engineer
Stealth AI Startup | Seed Stage | On-site
We’re hiring for an early-stage but fast-growing AI startup building a cloud-native analytics platform that turns large volumes of LLM output into structured, queryable intelligence for businesses and brands.
Their stack is fully on AWS, heavily event-driven, and designed for scale. They work with modern serverless and container-native infrastructure and actively use AI agents and automation across both engineering and product workflows.
We’re looking for a Software Engineer to help build and run the core data and infrastructure layer of our client’s platform.

*
Orchestrating workflows and event-driven systems
*
Managing containerised services with Docker and ECS

Setting up monitoring, alerting, and reliability practices

Optimising performance, cost, and scalability
*
Baking in security and least-privilege access from day one
*
Experimenting with AI tools and agents to automate workflows and improve productivity
What We’re Looking For
*
Strong AWS experience (especially ECS, Lambda, Step Functions, S3, EventBridge)
*
Solid Docker and container-native deployment experience
*
Python for data processing and automation
*
Experience building data pipelines and data lake architectures
*
Infrastructure-as-code (Terraform, CDK, or CloudFormation)
*
CI/CD and production engineering mindset
*
Systems thinking and comfort owning production workloads
*
Curiosity about AI tools, LLMs, and automation
Why Join
*
Real ownership of core infrastructure and architecture
