Favia; United Kingdom; Remote; GBP 90,000 - 130,000; Full time

Job summary

Favia is seeking a senior Database/Platform Engineer to own and scale PostgreSQL-backed services and vector data platforms. You will drive reliability, performance, and security while shaping automated workflows and self-service capabilities for the engineering org.

You will partner with AI, service, and platform teams to improve embeddings, vector search, and data hygiene, contributing to on-call readiness and observability improvements across cloud-native environments.

Qualifications

• 5+ years operating PostgreSQL in high-volume production environments, including performance tuning, replication, backup/restore, upgrades, and incident troubleshooting.

Responsibilities

• Scale and tune high-throughput PostgreSQL clusters that support continued global expansion and new product initiatives.
• Own PostgreSQL reliability fundamentals: WAL behavior, checkpoints, autovacuum, query planning, locking, replication lag, backup/restore, and capacity planning.
• Help build and operate vector data capabilities, including pgvector and dedicated VectorDB platforms where appropriate.
• Define production patterns for embeddings, approximate nearest neighbor indexes, metadata filtering, recall/latency tradeoffs, reindexing, data freshness, and drift management.
• Strengthen high-availability, disaster-recovery, PITR, and backup approaches through sound design and regularly validated procedures.
• Reduce manual operational work by building automation, improving process consistency, and enabling safe, low-friction database workflows.
• Improve observability and alert quality by championing meaningful metrics, reducing noise, and ensuring operational clarity across PostgreSQL and vector workloads.
• Enhance database security through robust access controls, disciplined patching and upgrade practices, encryption, auditability, and secure operational patterns.
• Contribute to modern platform initiatives, including containerized environments, infrastructure-as-code workflows, GitOps, reproducible deployments, and self-service database operations.
• Partner with service, AI, and platform teams to drive better performance patterns, operational readiness, data hygiene, and safe use of vector search across the engineering organization.
• Participate in on-call rotations with a long-term focus on making on-call predictable, well-instrumented, and shaped by preventative engineering.
