About the Role

We're looking for Senior Software Engineers to lead the design and development of cutting-edge AI applications for our clients. As part of our founding engineering team, you'll help define the standard for building production-grade generative AI products across industries and use cases.

By your second project, you'll have shipped more LLM-powered applications across more domains than most AI engineers in the world. You'll own projects end-to-end from initial design to deployment, collaborating directly with customers, leadership, and your fellow engineers to solve challenging, high-impact problems.

What You'll Do

• Design and develop AI-driven applications that integrate seamlessly with client systems and deliver measurable business value.

• Lead projects end-to-end from requirements gathering, system architecture, and prototyping to testing, deployment, and ongoing support.

• Collaborate closely with customers (often technical leaders) to understand their goals, propose solutions, and iterate rapidly.

• Drive engineering and cultural excellence by shaping technical standards, mentoring others, and contributing to how we learn, hire, and grow as a team.

• Experiment and innovate with LLM frameworks, model integration, and emerging AI tools to push the boundaries of what's possible.

Who You Are

• Experience: 10+ years of full-stack or backend-leaning software engineering experience.

• Leadership: Senior, Staff, or Engineering Leader (e.g., VP, Director, Head of, or CTO) with experience leading teams or technical projects.

• Builder Mindset: Proven ability to take ideas from 0 to 1, end-to-end ownership of product development.

• Technical Depth: Worked on highly technical products, ideally built for engineers or developer-focused users.

• Founder Mentality: Experience as a founder or founding engineer is a strong plus.

• Adaptable: Comfortable solving ambiguous problems and creating clarity where none exists.

• AI Enthusiast: Demonstrated interest in generative AI (LLM-based tools, LangChain, LangSmith, OpenAI API, etc.).

• Collaborative Communicator: Skilled at engaging with clients, understanding their needs, and translating them into technical solutions.

• Hands-On: You still love to code and enjoy being an individual contributor while leading by example.

Our Tech Stack

We are  tech stack agnostic; we work in our customers' environments and adapt as needed.
You'll gain deep expertise across foundational model integrations, tools like LangChain, LangSmith, Pinecone, OpenPipe, and ChromaDB , and various modern frameworks for building AI-powered systems.

What a Typical Day Might Look Like

• Serve as the tech lead on a client project, for example, automating a customer support workflow with AI agents or building a content moderation system powered by LLMs.

• Spend the morning tackling a high-priority feature (like building an evals suite or optimizing model performance).

• Join a customer standup with the client's CTO to review progress and make tradeoff decisions.

• Participate in a team lunch standup , sharing updates and sparking discussions about new AI frameworks or tools.

• End your day coding, mentoring peers, or joining a call with a potential client to discuss the technical feasibility of an upcoming project.

Soft Skills

• Strong communicator who thrives in cross-functional settings.

• Collaborative and humble values, helping others, and asking for help.

• Operates with integrity and a team-first mindset.

• Excited to shape not just products, but also culture and strategy .
