Staff AI Developer

The Opportunity

Euna Solutions is looking for a Staff 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 Atlanta, GA office.
