Job description

The Opportunity

Euna Solutions is looking for aStaff AI Developer to help define and drive the technical direction of our grant research platform. This is a hands-on, individual contributor role where you'll shape architecture, build critical systems, and push the boundaries of AI-enabled software development.


You'll work across two complementary systems:

  • A multi-tenant, cloud-native SaaS application built with Ruby on Rails (7+)
  • A Python-based data and discovery platform powered by FastAPI, PostgreSQL, Redis, and AI-driven ingestion workflows


If you're an AI-forward engineer who enjoys solving complex problems, working deeply in the code, and influencing system design at scale-this role is for you.


What You'll Do

  • Partner with Product to translate roadmap priorities into technical designs, implementation plans, and delivery strategies
  • Design and implement features across application, data, and infrastructure layers
  • Own and evolve core platform architecture across both Rails and Python systems
  • Make high-impact architectural decisions (service boundaries, modularization, data access patterns, scalability)
  • Build and optimize high-scale background processing systems (notifications, scoring, ingestion, exports, etc.)
  • Develop workflows spanning APIs, background jobs, ingestion pipelines, search/discovery, and reporting
  • Investigate production issues, identify root causes, and improve platform reliability
  • Implement AI-powered features including LLM orchestration, prompt workflows, and observability controls
  • Leverage AI-assisted development tools for coding, testing, refactoring, and documentation
  • Document architectural decisions and system behavior for long-term maintainability
  • Collaborate with Engineering, Product, Customer Success, and Support teams to continuously improve the platform


What You Bring

  • Proven experience as a Senior or Staff-level engineer building production SaaS or data platforms
  • Deep expertise in Ruby on Rails, including performance, architecture, and long-lived systems
  • Strong hands-on experience with Python (FastAPI or similar frameworks preferred)
  • Experience across both application platforms and data systems (APIs, ingestion, pipelines, reporting)
  • Strong background in background processing systems (e.g., Sidekiq, Redis, queues, schedulers)
  • Solid understanding of PostgreSQL schema design and performance optimization
  • Experience designing and operating production APIs (REST, auth, versioning, validation)
  • Comfort working in cloud-native, containerized environments
  • Experience with search and discovery systems (full-text, semantic, vector search)
  • A demonstrated AI-first development approach, using LLMs and automation tools
  • Strong understanding of security best practices (auth, data isolation, secrets management)
  • Experience with CI/CD pipelines, testing frameworks, and code quality tooling
  • Excellent communication skills, especially around technical decision-making


Nice to Have

  • Experience with enterprise or government-adjacent applications (compliance, auditability, security)
  • Familiarity with modern Rails frontend patterns (Hotwire, Turbo, Stimulus, Tailwind, ViewComponent)
  • Experience with async Python, Redis Streams, or workflow orchestration systems
  • Hands-on experience with LLM tools (OpenAI, Anthropic), embeddings, or vector databases
  • Experience with observability tools (Sentry, New Relic, Honeybadger, etc.)


Location:

This position will be hybrid in our Oakville, ON office.
