Backend Engineer (Elixir / Go)

Brickyard is building an end-to-end tech stack for image recognition in public spaces. As a Backend Engineer you design and implement the infrastructure required to ingest, process, and store high-volume image data utilizing Elixir for application orchestration and Go for high-performance processing components.

What will you do?

• Architecture & Development: You build and maintain a hybrid backend architecture using Elixir (Phoenix) for the core platform and go for performance-critical microservices.
• High-Volume Ingestion: You design data pipelines capable of handling, processing, and indexing (up to) 500,000 images per day with burst traffic support.
• Database Management: You own PostgreSQL architecture. You have responsibilities including schema design, query optimization, table partitioning, and indexing strategies for large-scale datasets.
• Infrastructure & Ops: You set up and maintain a production-ready environment, including CI/CD pipelines, containerization (Docker), and queueing systems (e.g., Oban).
• Reliability: You will implement comprehensive logging, monitoring, and regression testing to ensure system stability under load.
• Experience: Minimum 3–5 years of Backend engineering experience.
• Experience with Elixir (Phoenix Framework) for application logic.
• Experience with Go (Golang) for concurrent processing tasks.
• Database: Advanced knowledge of PostgreSQL, specifically regarding performance tuning, query planning, and managing large datasets.
• DevOps/Tooling: Experience with Docker, CI/CD setup and version control.
