AI-Native Full-stack Senior Developer @ Ellie.ai

Ellie.ai is a fast-growing SaaS company helping global enterprises blueprint and manage their complex data landscapes. Software development is undergoing a paradigm shift, and we want to stay at the forefront.

We believe the future of development lies in high-level orchestration. Our goal is to streamline the path from product requirements to shipped features by leveraging autonomous agents for execution, allowing our engineers to focus on what matters most:  technical design, complex logic, and quality assurance.

We are looking for a builder who will not only adopt this AI-native mindset but also help our team evolve toward these new ways of working.

The Mission: Orchestrating the Future of Data Modeling

As a part of our AI-product stream, you will work together with our development team to take Ellie’s AI capabilities to the next level. Your focus will be on building the infrastructure for a more autonomous and context-aware platform:

• Agent Orchestration:  Working with the team to decompose complex data modeling tasks into manageable, executable steps.
• Context-Aware Interfaces:  Developing seamless UI components that understand the user’s workflow and provide real-time assistance.
• A2A Architecture:  Participating in the design and implementation of how specialized AI agents communicate with each other and integrate into our platform.

A New Paradigm: Design, Delegate, Review, Own

As an AI-native senior developer at Ellie, you don't just "prompt and pray." You focus on technical excellence to ensure that our shared product vision is executed accurately. Your workflow is defined by four pillars:

1. Design:  You collaborate with Product Management and UX Designers to translate requirements into solid technical blueprints. You spend focused time mapping out logic and data structures before feeding them into AI tools.
2. Delegate:  You offload the heavy lifting, repetitive tasks, and boilerplate code to agents (Cursor, Claude Code, etc.) based on your technical design.
3. Review:  You act as a critical quality gatekeeper. You verify that the solution is technically sound, secure, and fits our standards.
4. Own:  You take full responsibility for the end result, ensuring it integrates perfectly and provides real value to our users.

What We Expect from You

Bonus points for:

• Data Domain: Familiarity with Data Modeling or Data Governance.
• AI Ecosystem: Experience with Python and various model providers (e.g., AWS Bedrock, OpenAI, Anthropic).
• Cloud & DevOps: Hands-on with AWS (Lambda, S3, EC2), Docker, and production-grade CI/CD.
• Observability: Experience with LLM tracing and monitoring (we use Langfuse and Datadog).
• Startup Mindset: Experience in fast-paced environments and a preference for high autonomy.
