About The Position

Applecart is the leading technology company that C-suites rely on to reach business-critical decision makers. The most important decisions are made by the hardest people to reach and influence. Historically, C-suite leaders have lacked the tools to reach the stakeholders who matter most to their business. The C-suites of hundreds of Fortune 500 companies, major agencies, trade associations, nonprofits, and governments use Applecart to put their best content in front of business-critical decision makers and those they trust — from policymakers and investors to CEOs, key employees, members of the media and more. Decision makers are informed by what they read, learn from advisors, hear from colleagues, and discuss with family and friends. To break through to them, you must reach them through the only channel that really moves them: those they know and trust. Applecart’s platform uses publicly available data to map billions of social relationships between nearly every American adult and enable clients to deliver content directly to decision makers and those who matter most to them.
We are hiring a Senior Data Infrastructure Engineer in our New York City office.

Here are a few examples of what we work on:
Enabling unified data governance capabilities for all Applecart’s data assets
Scaling our compute and orchestration layer.
Creating and scaling agents to enable engineers and users on their workflow and data needs
About the Role:
We’re looking for a seasoned engineer leader who combines deep hands-on expertise with broad strategic impact. In this role, you won’t just maintain our systems; you will help architect the evolution of our data backbone. You will be responsible for ensuring our data infrastructure scales ahead of the business’ needs while setting the technical standard and mentoring the engineers who build alongside you.
What You’ll Do:
Design, build, and operate scalable data infrastructure that serves as the foundation for Applecart’s services.
Own the roadmap for core data services (Apache Iceberg, EMR, Unity Catalog, Dagster, Snowflake) ensuring maximum uptime, reliability, and performance.
Collaborate with Principal Architect to design self-service platforms that empower other teams to deploy and manage their own workflows without bottlenecks.
Drive high-level initiatives in security, cost efficiency, and developer experience across the entire data organization.
Define data reliability standards through advanced observability, proactive monitoring, and automated alerting.
Set technical protocols and scale operational quality through proactive advocacy and documentation.
Scale the team’s impact by mentoring junior/mid-level engineers and fostering a culture of high-standard, collaborative workflows.
Who You Are:
You are an experienced software engineer who is passionate about data infrastructure and eager to deepen your expertise in this space. You take initiative to experiment with new tools and approaches, building POCs to validate ideas before committing to implementation. You possess a growth mindset, taking pride in solving complex problems from inception to delivery while elevating team standards. You prioritize solutions that are both technically sound and commercially viable, working in lockstep with Product managers to ensure data infrastructure enables business goals.
