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.
