Job Summary

We are looking for someone with deep experience optimizing databases, both SQL and NoSQL, for performance and scale. Our platform ingests and analyzes high-volume time-series data. We are looking for a candidate with experience with technologies such as PostgreSQL, Timescale, Redis, and Elasticsearch. This is a hands‑on backend engineering role in Go, not a DBA position. Day-to-day, you’ll be writing code and building across the platform. Your database expertise will be especially valuable as we tackle performance and scalability challenges across these data stores. Once that work is in a solid, maintainable place, you’ll contribute across other backend projects as well.

What You’ll Do

Backend Development (Primary Focus)

• Design, build, and ship backend services and features in Go with a GraphQL API layer
• Write clean, efficient, and maintainable production code across the full development lifecycle
• Contribute to system design, architecture, and implementation of scalable services across multiple coordinated services

Database Optimization (Specialty Area)

• Analyze and optimize PostgreSQL/TimescaleDB queries using EXPLAIN ANALYZE, identifying slow paths in time‑series and relational workloads
• Design and implement indexing strategies (B-tree, GIN, BRIN, partial, hypertable indexes) tailored to query patterns
• Optimize Redis caching layers and Elasticsearch indexing/query performance
• Identify and resolve performance bottlenecks across the full data path – ingestion, storage, query, and retrieval
• Evaluate and recommend data store choices (SQL vs. NoSQL) for new features based on access patterns and scale requirements

Data Modeling & Schema Design

• Design schemas that support both performance and scalability across PostgreSQL, TimescaleDB, and Elasticsearch
• Implement partitioning, hypertable, and retention strategies for high‑volume time‑series data
• Balance tradeoffs between performance, maintainability, and data integrity across SQL and NoSQL stores
• Build and operate services deployed on Kubernetes across AWS and GCP
• Design for reliability, fault tolerance, and high availability with proper observability (OpenTelemetry, Prometheus)

Performance & Scalability

• Optimize across the full stack: application code, database queries, caching layers, and search indexes
• Troubleshoot complex production issues across services, data pipelines, and data stores
• Use distributed tracing and metrics to identify and resolve latency and throughput bottlenecks

Cross‑Functional Collaboration

• Partner with product, data, and engineering teams to deliver high‑impact solutions
• Contribute to technical discussions and help drive pragmatic engineering decisions

What You Bring

Experience

• 7+ years of backend software engineering experience
• Strong track record of building and operating production systems at scale
• Hands‑on experience optimizing PostgreSQL (and ideally TimescaleDB or similar time‑series extensions) in production
• Strong understanding of query performance, indexing strategies, and execution plans
• Experience with at least one NoSQL data store (Redis, Elasticsearch, or similar) in a production capacity
• Experience working with large datasets and high‑throughput data ingestion pipelines

Technical Skills

• Proficiency in Go is highly desired; we’ll invest in training the right engineer
• Experience with cloud platforms (AWS and/or GCP)
• Familiarity with Kubernetes and containerized systems
• Bonus: experience with GraphQL APIs, OpenTelemetry, Kafka, or time‑series databases

Compensation

Individual compensation is determined by skills, qualifications, and experience. Compensation includes salary, equity, and a discretionary bonus.

Work Authorization

Applicants must have legal authorization to work in the United States. Effodio does not sponsor employment visas for this role.
