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.)
