Senior PostgreSQL Storage & Systems Engineer

About the Role:

We’re looking for a

Senior PostgreSQL Developer

with deep expertise in

PostgreSQL’s storage engine internals

to join our core database engineering team. This role will focus on

low-level database internals , particularly around storage, WAL, checkpointing, and buffer management—while helping evolve PostgreSQL for

cloud-native, high-performance, and distributed environments . You’ll work with some of the sharpest minds in systems and database engineering, and contribute directly to improving how PostgreSQL runs at scale in modern cloud architectures. If you’re someone who has navigated the PostgreSQL source tree, written or tuned storage code, and is excited about pushing PostgreSQL further into the cloud-native era, we want to talk to you. Key Responsibilities:

Work on

PostgreSQL storage internals

— buffer manager, WAL, background writer, vacuum, checkpoints, and crash recovery Design and build enhancements for

cloud-native PostgreSQL workloads

(e.g., tiered storage, snapshotting, IO scaling) Contribute to PostgreSQL extensions or core patches related to storage engine functionality Optimize disk IO paths, memory usage, and write-ahead logging for large-scale databases Collaborate with the platform team to make PostgreSQL run efficiently on

Kubernetes, containerized environments , and across

multi-cloud platforms (AWS, Azure, GCP) Conduct deep analysis of performance regressions, memory leaks, and IO bottlenecks using perf, gdb, strace, etc. Participate in code reviews, RFCs, and upstream community discussions where applicable Drive innovation in

replication ,

backup , and

HA strategies

through low-level systems improvements Requirements:

5+ years of experience working with PostgreSQL internals , especially storage subsystem Strong systems-level programming skills in

C

(and optionally Rust/Go) Solid understanding of

WAL internals , buffer pool management, page formats, and disk write flows Experience working with

Linux systems internals

(filesystems, IO schedulers, memory management, etc.) Prior contributions to

PostgreSQL open-source community

is a major plus Familiarity with

cloud platforms

(AWS, Azure, or GCP) and experience optimizing PostgreSQL for virtualized or containerized environments Exposure to

Kubernetes ,

container orchestration , and

persistent storage architectures Bachelor’s or Master’s degree in Computer Science, or equivalent hands‑on experience Nice to Have:

Experience building PostgreSQL-compatible services in the cloud (e.g., Aurora, AlloyDB, Cloud SQL) Familiarity with

columnar storage ,

compression techniques , or

distributed filesystems Deep knowledge of

PostgreSQL replication internals

or custom backup engines Experience with observability tooling and performance benchmarking at scale What We Offer:

Opportunity to work on

cutting-edge database internals

powering real-world production systems Work with a collaborative, high-caliber team across

USA and India Competitive compensation and equity A flexible work environment focused on innovation, ownership, and impact
