About the Role

We are seeking a Senior AI Software Engineer to join this fast-moving AI Labs team and help build the next generation of AI-powered products and systems.

This is a highly technical, hands-on role that combines software engineering, AI experimentation, product thinking, and rapid prototyping. You'll work directly with senior technical and business leaders to design, build, test, and deploy AI-driven applications that solve meaningful business problems.

The ideal candidate is equally comfortable building customer-facing prototypes and designing scalable backend systems. You'll own projects end-to-end, from concept through production deployment, while contributing to architectural decisions, AI evaluation frameworks, and agent-based workflows.

This position reports directly to the CTO and offers exceptional visibility, autonomy, and influence over how emerging AI technologies are applied in production environments.

Responsibilities

• Build production-grade applications using TypeScript and modern AI development tools

• Develop full-stack prototypes that clearly demonstrate capabilities to internal stakeholders and enterprise customers

• Design, test, and optimize prompts across leading foundation models including OpenAI, Claude, and Gemini

• Implement context engineering strategies that provide AI systems with the right information at the right time

• Design and build agentic workflows and AI-powered automation systems

• Create frameworks for monitoring, testing, and evaluating LLM performance

• Analyze large datasets to identify opportunities for AI-driven solutions

• Architect scalable systems capable of supporting multiple enterprise clients

• Collaborate with technical and business stakeholders to rapidly validate ideas and deliver solutions

• Contribute to AI strategy discussions and help guide technical decision-making around model selection, architecture, and deployment

Required Qualifications

• Bachelor's degree in Computer Science, Data Science, Statistics, Engineering, or a related field (or equivalent practical experience)

• Minimum 7 years of professional software engineering experience

• Proven experience leading or owning AI/LLM projects from concept through deployment

• Strong full-stack development experience with:

  • TypeScript

  • React

  • SQL

• Experience working with modern LLMs and AI APIs, including OpenAI, Claude, and/or Gemini

• Demonstrated experience with prompt engineering, model evaluation, and AI application development

• Experience designing and implementing agent-based systems or AI-driven workflows

• Strong understanding of:

  • System architecture

  • APIs

  • Scalability principles

  • Database design

  • Open-source ecosystems

• Experience creating structured testing methodologies and performance metrics for AI systems

• Excellent written and verbal English communication skills

• Ability to work independently in ambiguous, fast-changing environments

• Strong judgment regarding when AI outputs can be trusted and when deeper engineering validation is required

Preferred Qualifications

• Experience working within high-growth startups or innovation-focused environments

• Experience building LLM testing and evaluation frameworks

• Proficiency with Python, Java, or other languages commonly used for AI development and data processing

• Experience within retail technology, e-commerce, recommendation systems, or personalization platforms

What Success Looks Like

• Delivering AI-powered solutions from concept to production

• Building scalable systems that can support multiple enterprise clients

• Rapidly prototyping new AI capabilities and validating them with stakeholders

• Establishing reliable testing and monitoring practices for LLM-based applications

• Driving technical innovation while maintaining strong engineering fundamentals

If you're excited about building production-grade AI systems, working directly with executive stakeholders, and helping shape the future of enterprise AI applications, we'd love to hear from you.
