Platform Engineer (Databases & Storage)
About The Position
We’re looking for a Senior Platform Engineer — Databases & Storage to join the team at World Labs. In this role, you will own and evolve the transactional and storage backbone of our platform — the systems responsible for reliably storing, serving, and scaling the core data that powers both our products and our research. You’ll work on problems across OLTP systems, storage, and distributed infrastructure, designing systems that are fast, reliable, and simple to operate. You will operate as a senior technical leader, helping shape architecture, guiding other engineers, and setting a high bar for execution. This is a highly impactful role at the intersection of infrastructure, product, and research, where your work directly affects developer velocity, system reliability, and overall cost (TCO) of the platform.
Requirements
- 5–10+ years of experience building and operating production systems at scale, with ownership of critical infrastructure
- Strong experience designing and operating OLTP systems and transactional databases (e.g., Postgres, MySQL, or similar)
- Deep understanding of data modeling, indexing, transactions, concurrency, and consistency tradeoffs
- Proven experience owning systems with high reliability and performance requirements in production environments
- Strong experience debugging real-world production issues (e.g., latency, contention, replication, failure modes)
- Experience designing and scaling distributed systems or large-scale infrastructure
- Demonstrated ability to lead technical decisions and drive projects end-to-end
- Strong ability to balance performance, reliability, and cost (TCO) in system design
- Experience operating in ambiguous, fast-moving environments, with a bias toward execution
- Strong collaboration skills across engineering, product, and research teams
Nice To Haves
- Experience building infrastructure for AI/ML systems or data platforms
- Familiarity with large-scale data pipelines, training systems, or model infrastructure
- Experience with storage systems, query engines, or distributed databases
- Prior experience in startup or early-stage environments
- Experience mentoring engineers or acting as a technical lead for a system or domain
Responsibilities
- Design, build, and operate the transactional backbone (OLTP systems) of the World Labs platform
- Architect and scale database and storage systems for high-throughput, low-latency workloads
- Own data modeling, indexing strategies, and query performance across critical services
- Debug and resolve complex production issues (e.g., contention, replication, performance bottlenecks)
- Build systems that are reliable, observable, and cost-efficient, with strong operational rigor
- Partner closely with product engineers to enable fast iteration and a great developer experience
- Collaborate with research teams to support evolving data pipelines and model workflows
- Drive improvements in reliability, scalability, and performance across the platform
- Mentor engineers and contribute to building a high-trust, high-performance engineering culture
Benefits
- Base salary plus equity awards and annual performance bonus
