SaaS • B2B • API

LocalStack is a local cloud development platform that simulates cloud environments on a customer's own infrastructure so software teams and AI agents can develop, test, debug, and validate cloud applications without provisioning real cloud resources. It runs as lightweight containerized emulators that expose the same APIs, SDKs, and Infrastructure-as-Code interfaces (CDK, Terraform, Pulumi) used in production, with support for 120+ AWS services and emulators for Snowflake (and Azure coming soon). LocalStack is designed to speed feedback loops, reduce cloud costs, surface security risks and bugs earlier, and enable AI-native development workflows. It is used by thousands of organizations and has scaled to hundreds of millions of Docker pulls.

📋 Description

• Expand and harden LocalStack’s AWS emulator • Take ownership of individual AWS services and make them behave as closely as possible to real AWS • Independently move AWS services from moto-backed to fully first-party implementations • Own persistence store design, full API operation coverage, and conformance to LocalStack conventions • Close parity gaps using snapshot tests against real AWS • Act as first responder for owned services and triage customer-reported parity bugs • Turn around parity bugs within a 5-day median, including issues surfaced through Terraform and CDK • Contribute reusable testing infrastructure such as conformance harnesses, snapshot tooling, and fixtures • Independently scope and sequence an internalization from API-documentation analysis through shipped provider by month 12 • Use modern AI coding and agentic tools while maintaining software quality and reliability

🎯 Requirements

• 3+ years of professional software engineering experience • Strong engineering fundamentals • Experience working from a written specification against a system you cannot see inside, such as public APIs, protocols, wire formats, parsers, compilers, SDKs, emulators, or reverse-engineering projects • Strong testing mindset • Hands-on experience with AI coding and agentic development tools, used substantially to build and ship real software • Fast learning and strong problem-solving skills • Open-source contribution experience, particularly sustained involvement in an existing project (strong plus) • Experience working with AWS at application or platform level (strong plus) • Experience with distributed systems, storage, or protocol conformance (strong plus) • Deep AWS expertise (nice to have) • Experience with Infrastructure as Code, such as Terraform, CDK, or Pulumi (nice to have) • Experience with Kubernetes and microservices architecture (nice to have) • Short motivation outlining why you are the perfect candidate

🏖️ Benefits
