Job description

At Amperity, we’re an AI-first company helping the world’s leading brands create personalized customer experiences that build loyalty and fuel growth. Our AI-powered Customer Data Cloud, built on multi-patented technology, enables more than 400 global brands, including Alaska Airlines, Wyndham Hotels & Resorts, and DICK’S Sporting Goods, to turn customer data into a competitive advantage.

We unlock the full value of customer data with simplicity and speed. AI is at the core of our platform and the way we work — from powering advanced identity resolution and predictive analytics to streamlining internal workflows and decision‑making. It’s not just a capability; it’s part of our DNA.

Our team thrives on curiosity, collaboration, and transparency, fostering a culture where everyone can contribute, learn, and grow. We welcome talented individuals from diverse backgrounds to help us remove data bottlenecks, accelerate business impact, and push the boundaries of what AI can do for the world’s most innovative companies.

With offices in Seattle, New York City, London, and Melbourne, you’ll join a fast-growing team tackling critical challenges at the intersection of AI, data, and customer experience. Ready to make an impact? Let’s talk.

The Role

The MAX team drives a critical part of the platform that intersects both product and infrastructure spaces. The products we manage allow users to gain valuable insights into their data and make important decisions from those insights in ways that no other platform can. An immense data warehouse and query stack that we oversee powers these capabilities, and it analyzes some of the largest datasets that our enterprise customers can throw at us. Our horizon includes building predictive analysis tools, real‑time decisioning engines, and agentic toolchains. We are biased for action, value, and succeed together in a highly collaborative environment. We are bullish on leveraging AI coding tools, such as Codex and Claude to accelerate our engineering capabilities.

Interesting Problems

• Own batching and real‑time streaming systems that handle large amounts of structured customer, product, and event data.
• Building full‑stack experiences and toolsets to help users visualize their data, understand their customers, surface the most impactful insights, and take meaningful action based on those insights.
• Integrate our services into the operating core of the businesses we serve.
• Change how marketers use their customer data through unique and intuitive product experiences.
• Build agentic tools for our customers to use, and an MCP to allow external AI tools to take advantage of the Amperity platform.

About You

• 5+ years of experience working with large‑scale data‑oriented systems. Bonus if you have experience with Trino, Spark, Delta Lake, & Kubernetes.
• Track record building, scaling, and managing production environments.
• Excited about using functional languages (like Clojure!).
• Passionate about building elegant user experiences on top of complex technologies.
• Open‑minded, collaborative, inclusive, and inspired by your customers' success.
• Curious about using AI coding tools such as Claude and Codex to help accelerate your development.

Technologies We Use

• Open source large‑scale database engines such as Spark & Trino.
• Microservices architecture using Clojure as the primary programming language.
• A web stack based on ClojureScript and the React family of tools.
• Cloud‑first architecture using technologies like Terraform and Kubernetes in a multi‑cloud platform.
• Claude for development with various MCPs to increase its effectiveness.
