Software Engineer

Sage Recruiting is looking for a Founding Engineer for a seed-funded startup based in New York. Our client is supported by top Silicon Valley funds, as well as individuals from esteemed institutions such as NVIDIA, Docker, AWS and Redis Labs. The founding team members are all from a company that was acquired in 2019 by a publicly traded AI-focused company.

Our client is focused on building a next-generation serverless data platform that can revolutionize how data engineers and scientists work. Their goal is to abstract data infrastructure away from engineers and data scientists, allowing them to focus solely on building data-driven applications using concepts they already know. The initial system was introduced to the market a few months ago and is now live at enterprise scale.

What You’ll Do

Lead design and development of the product’s web-based UI, including key workflows, dashboards, and supporting visual interface

Work closely with engineering leadership and product to ship fast, user-friendly features

Leverage an existing design system to build and extend clean, scalable components

Contribute to core engineering efforts by connecting UI to backend services (REST APIs, cloud workflows)

Occasionally assist with backend tasks when needed (e.g., endpoint wiring, basic cloud infra)

Work with the customer to ensure a strong user-centred design

What We’re Looking For

3+ years of experience building polished, accessible and responsive UIs for AI or developer-facing tools

Expertise with React

Proven experience using modern design systems in production environments

Comfortable working with REST APIs, Git workflows, CI/CD pipelines and AWS Cloud services

Experience with Python and FastAPI, Flask or similar

Open source experience/projects

Nice to Have

Experience working with infrastructure or data platforms (e.g., Snowflake, Databricks)

Exposure to CLI-based workflows

Knowledge of SQL or analytics tools

Why Join

Join a founder-level team solving complex infrastructure problems in elegant ways

Help shape the front-end of a product already in use by engineers and data scientists at scale

Work with a high-calibre, engineering-first team backed by industry-leading investors

Competitive salary + early equity

100% remote, async-friendly work culture
