Senior Data Platform Engineer

About the Company

Gemini is a global crypto and Web3 platform founded by Cameron and Tyler Winklevoss in 2014, offering a wide range of simple, reliable, and secure crypto products and services to individuals and institutions in over 70 countries. Our mission is to unlock the next era of financial, creative, and personal freedom by providing trusted access to the decentralized future.

The Department: Platform

Our Platform organization’s purpose is to enable Gemini to scale effectively and empower our engineering teams to focus on building innovative financial products and experiences for individuals around the world. Platform focuses on building a scalable and secure foundations platform, enabling Engineering to deploy, validate, and operate their services in production, improve resiliency of the service and increase organizational efficiency by reducing operational toil and increase system efficiency through architectural evolution.

The Platform team engages directly with our other engineering teams to onboard them onto our platform systems, reviewing and recommending design and architectural decisions, and guiding our engineering teams on how to implement the tooling provided by the larger Platform organization required to ensure systems can scale and react to changing conditions, with continuous improvement loops.

The Role: Senior Data Platform Engineer

As a Senior Data Platform Engineer, you'll be an SRE for our data infrastructure: responsible for the reliability, automation, and operability of the database and datastore fleet, not just tuning any single engine. You'll work closely with data engineering and product engineering teams to build self-service, automated foundations that let teams provision, scale, and operate their own datastores safely.

Your role centers on deep relational database expertise (PostgreSQL, Aurora) - internals, replication, failover, backup/recovery, and query performance - paired with the automation and tooling to run that expertise at scale rather than by hand. You'll extend that same automation-first discipline to the other datastores in our fleet - NoSQL/document, columnar, key-value, and streaming systems - so that scaling, failover, and provisioning are repeatable and largely self-service. You'll drive improvements to observability, incident response, and uptime posture through proactive ownership of the platform, and you'll bring SRE practices (SLOs, error budgets, toil reduction, blameless postmortems) to how we run data infrastructure.

This role is ideal for someone who thinks in systems and automation first, thrives on cross-team collaboration, and wants to reduce operational toil across a diverse set of database technologies in a fast-paced, cloud-native environment.

Responsibilities

• Automation and Reliability Engineering: Build Infrastructure as Code (IaC), CLI tools, and CI/CD-driven automation that make database provisioning, scaling, failover, and deployment self-service, consistent, and repeatable across environments - this is the core of the role, not a supporting activity.
• Database Scaling and Optimization: Serve as the team's depth on relational database systems (e.g., Amazon Aurora, PostgreSQL) - replication topologies, failover, backup/recovery, and query/engine-level performance.
