Founding Platform Engineer

Join an early-stage marketing technology company as its first dedicated platform engineer. You will own the infrastructure and data platform, building reliable, high-performance systems that support real-time data processing and product growth. What You’ll Do

• Build and operate the platform that ingests and processes high volumes of real-time data.
• Take ownership of infrastructure and data platform priorities, setting the roadmap for performance, reliability, and scale.
• Work closely with product engineers and technical leadership to build systems for large consumer businesses.
• Develop services and pipelines designed to scale to very high job volumes, evaluating technologies such as Kafka and lower-level languages where appropriate.
• Build data materialization and query capabilities for fast joins and aggregations across large datasets.
• Profile and tune ClickHouse and PostgreSQL, using benchmarks, query plans, and system diagnostics to improve performance.

• 4 to 10 years of experience in backend, platform, infrastructure, site reliability, distributed systems, or systems engineering.
• Hands-on coding experience and a track record of improving the speed, reliability, and scalability of data-intensive systems.
• Experience across system architecture, databases, and scaling challenges.
• Familiarity with Python, ClickHouse, PostgreSQL, Kafka, distributed systems, real-time data pipelines, and OLAP or OLTP databases.
• Experience operating ClickHouse, PostgreSQL, or Kafka at scale is a plus.
• Strong foundations in computer science, physics, mathematics, or engineering, or equivalent practical experience.
• Comfort owning open-ended platform work and working closely with a small product and engineering team.
