This position requires office presence of a minimum of 5 days per week and is only located in the location(s) posted. No relocation is offered.
We’re looking for an AI-Native Software Engineer (Principal Engineer) who blends strong fullstack Python engineering with hands-on experience building intelligent systems powered by LLMs, agent orchestration, and AI-augmented development workflows.
This is not a traditional software engineering role. We want someone who has fully integrated AI into how they design, code, test, debug, and deliver solutions — and who can work side-by-side with business partners to turn ideas into production-ready applications with speed and precision.
In this role, you’ll help shape requirements in real time, build scalable AI-enabled systems, and create seamless integrations across backend services, agent frameworks, data sources, and user-facing applications.
What You’ll Do
- Partner directly with business stakeholders to understand needs, refine ideas, and translate goals into working software solutions.
- Operate in a collaborative “2-in-a-box” model, co-owning outcomes from ideation through delivery.
- Build and integrate AI-powered applications using Python and frameworks such as FastAPI, Flask, or Django.
- Design and orchestrate intelligent workflows using LLMs, LangGraph, MCP, and multi-agent systems.
- Develop and optimize prompts, context strategies, session memory, retrieval pipelines, and vector-based search to improve agent performance.
- Use AI coding assistants and agentic development tools as a core part of your workflow for prototyping, refactoring, testing, documentation, and code review.
- Integrate backend services, APIs, databases, vector stores, third-party platforms, and machine learning systems into robust end-to-end solutions.
- Implement testing, monitoring, evaluation, logging, and CI/CD practices to improve reliability and system performance.
- Apply best practices in security, privacy, scalability, and operational resilience across AI and backend systems.
What You’ll Bring
- A strong ability to work directly with business partners and turn ambiguous ideas into clear, deliverable engineering solutions.
- Clear communication skills with the ability to explain technical concepts to non-technical audiences.
- Deep, practical use of AI tools in software development, with examples of how they’ve meaningfully improved your speed, quality, and approach.
- Experience building AI agents, conversational systems, RAG pipelines, or multi-agent workflows in real-world environments.
- Strong problem-solving skills, technical curiosity, and a builder mindset.
- A passion for exploring emerging AI tools and applying them in ways that create real business value.
What You’ll Need
- Strong experience in fullstack Python development, including backend frameworks such as FastAPI, Flask, or Django.
- Experience designing and integrating REST APIs, backend services, and database solutions across SQL and/or NoSQL environments.
- Hands-on expertise with LLMs, prompt engineering, context engineering, session management, retrieval strategies, and vector search.
- Experience with LangGraph, MCP, or similar agent orchestration frameworks.
- Familiarity with cloud platforms such as AWS, GCP, or Azure.
- Experience with Docker, CI/CD pipelines, testing frameworks, and production deployment practices.
- A strong foundation in secure, scalable, and maintainable software design.
If you’ve already embraced AI as a core part of how you build software — and you’re excited to partner closely with the business to deliver high-impact solutions quickly — we’d love to hear from you.
