Job description

ComResource is looking for a Senior Elixir Engineer.

We’re looking for a Senior Elixir Engineer to step into a high-impact, 90-day engagement and stabilize a production Elixir/Phoenix system under real growth pressure. This role is focused on application performance and runtime behavior—someone who can quickly diagnose whether issues are CPU-bound, I/O-bound, or memory-related, and implement targeted fixes. They’ll be working directly in the codebase, optimizing Ecto queries, database access patterns, and concurrency, while improving scheduler utilization, reducing memory pressure, and ensuring the system performs reliably under both sustained and burst traffic.

Beyond fixing immediate issues, we need someone who can raise the maturity of the codebase and the team. That includes refactoring critical areas safely, eliminating inefficient patterns (like N+1 queries and heavy request paths), and introducing better approaches around async processing, caching, and architectural boundaries. This person should be comfortable mentoring engineers and guiding tradeoffs—helping the team understand how to build for performance and reliability, and when to offload work to background jobs or managed services. The goal is not just to fix the system, but to leave it in a state that is faster, more stable, and able to scale with confidence.

Responsibilities:

  • Own application performance and runtime behavior under production load
  • Diagnose CPU, I/O, and memory bottlenecks
  • Optimize BEAM scheduling, concurrency, and system performance
  • Improve database performance and eliminate inefficient queries
  • Implement caching strategies (ETS, Redis)
  • Tune external dependencies such as PostgreSQL and APIs
  • Support load testing and system validation
  • Refactor codebase to improve maintainability and performance
  • Establish design patterns and architectural standards
  • Improve testing strategy, coverage, and release confidence
  • Reduce technical debt without disrupting development
  • Ensure production issues can be reproduced and resolved efficiently
  • Mentor engineers on Elixir, concurrency, and performance optimization
  • Guide architectural decisions and system design improvements

Essentials:

  • Deep expertise in Elixir and BEAM performance tuning
  • Strong knowledge of OTP and concurrency patterns
  • Experience optimizing PostgreSQL and Ecto queries
  • Ability to diagnose system bottlenecks
  • Experience with observability tools
  • Experience in cloud environments

Desired:

  • Experience with Phoenix and LiveView
  • Experience with Oban or job processing systems
  • Familiarity with ETS and Redis
  • Experience with profiling tools
  • Experience with high-throughput systems
