Full job description

LocalStack - the Local Cloud Sandbox for Developers and AI Agents

We are a fast-growing Series A startup building cutting-edge technology to revolutionize cloud development processes and support highly efficient dev&test feedback loops. We’ve closed our last $25mil round in Q4 2024, led by Notable Capital, CRV and Heavybit.

LocalStack is a local cloud development platform. LocalStack makes it easier, faster, and less expensive for software teams to ship reliable, high-quality applications to the cloud.

The cloud was built to run software, not to support AI-native development workflows. As the world's leading local cloud development platform, LocalStack provides secure local sandboxes that simulate cloud environments, enabling AI agents and software developers to find and fix risks faster and more effectively than they can in the cloud.

Our customer base ranges from SMBs to Global Fortune 500 companies. Our clients include companies like NASA, Harness, IBM, Workday, Comcast, Apple, 3M, Block and many more.

We are sustainably growing our globally distributed teams across GTM, operations and engineering. In 2025 we almost doubled in size and continue to grow across all areas in 2026.

LocalStack is headquartered in Zurich/Switzerland , with a small engineering office in Vienna/Austria and remote team members from 25 countries including the US, FR, UK, CA, ES, and many more!

Deliver high-quality marketing pages quickly and reliably, enabling the marketing team to launch campaigns on schedule without engineering bottlenecks.
Maintain a fast, accessible, and technically healthy website, consistently meeting performance, responsiveness, accessibility, and Core Web Vitals standards.
Ensure every published page meets a high quality bar, with minimal production defects through rigorous QA of both manually created and AI-generated content.
Improve website effectiveness through data-driven optimization, contributing to measurable improvements in conversion rates, user engagement, and organic traffic.

Ability to translate Figma designs into responsive web pages

Courage: we dare to innovate. We embrace bold challenges and take calculated risks to move the needle. We step outside our comfort zones, experiment fearlessly, and turn setbacks into springboards for growth.
Excellence: we chase the extraordinary. We chase excellence by pushing boundaries and delivering results that go beyond the ordinary, constantly raising the bar and striving for greatness in everything we do. Excellence is not just the outcome, itʼs how we approach every task with purpose, passion, and a commitment to delivering exceptional value.
