Role Overview

Job Description: Engineering Lead (AI-Powered Digital Products)

We’re looking for an Engineering Lead who builds systems with clarity, speed, and leverage.

This role is central to how we operate. You’ll lead through architecture, code, and clean abstractions—not people management. You’ll work directly with product, design, and generalists to create the internal infrastructure that allows our small team to operate at 5–10x capacity.

We’re not shipping AI features to check a box. We’re building AI-native workflows—tools that shift how people think, work, and ship. Every system you help build will start with internal use. Once it consistently improves human output, we’ll commercialize it.

This role requires a builder who thinks long-term but ships in short loops. Someone who sees product quality and infrastructure quality as two sides of the same problem.

What you’ll do:

• Build backend systems and infrastructure from scratch—APIs, pipelines, orchestration, storage.
• Own full-stack workflows: light front-end (React, Next.js) to backend (Python, Node, etc.) to deployment.
• Design and evaluate LLM-integrated workflows that assist or automate high-value tasks.
• Define system architecture and technical direction with an eye toward composability and maintainability.
• Collaborate across product and design to scope, build, and iterate quickly, internal-first, user-facing second.
• Evaluate and integrate emerging AI capabilities (retrieval, agents, reasoning frameworks, etc.).
• Identify, adapt, and integrate open-source tools and frameworks where useful—always optimizing for speed, clarity, and leverage.
• Debug, refactor, and improve systems as they grow—no handoffs, no silos.

What you bring:

• Strong experience building and scaling backend systems in production (Python, Node, Go, or similar).
• Familiarity with LLMs, prompt engineering, or workflow-based AI integrations.
• Experience in building and iterating on algorithms and their use with AI workflows.
• Comfort working across the stack—you don’t need to love front-end, but you’re not blocked by it.
• Ability to work autonomously and make smart decisions with imperfect information.
• Fluency with cloud infra (AWS, GCP, etc.), CI/CD pipelines, containers, and deployment.
• Systems thinking: you design for long-term simplicity, not short-term hacks.
• Clear communication—concise, honest, direct.

Nice to have (but not required):

• Experience with agentic systems, vector databases, AI memory implementations, or task routing logic.
• Background in developer tools, internal platforms, or automation infrastructure.

Why this contribution matters:

• Every product we build is powered by the systems you help create. If our infrastructure is tight, modular, and expressive—we move faster, ship better, and think more clearly as a team.
• This isn’t a layer-above-the-team engineering role. This is the team. If you're looking for depth over headcount, clarity over consensus, and the chance to shape how AI systems get built from the inside out—we’d love to talk.

What We Offer:

• Flexibility: Fully remote work with flexible hours. Our engagement begins on a part-time basis as the candidate establishes familiarity with the company, with the opportunity to transition into a full-time contract as mutual alignment and goals are achieved.
• Impact: A chance to shape the direction of new and innovative products.
• Collaboration: Work closely with an entrepreneurial team passionate about technology and innovation.
• Growth Opportunities: Be part of a growing venture builder where you can take ownership and make a real difference.

How to Apply:

Please submit your resume along with any examples of successful product launches or case studies (if available).

• We are open to professionals from all age groups and backgrounds. Your experience, drive, and passion for creating impactful products are what matter most.
