Position

Title: Principal Software Engineer (AI Engineer with Customer-Facing)

Location: Remote

This is a senior-level, hands-on technical role for someone who can lead AI solution design, build advanced prototypes, and advise high-level customer stakeholders with credibility and confidence.

You’ll work directly with CTOs, chief architects, and engineering leaders to uncover real challenges, design smart solutions, and drive full-cycle AI delivery—from first sketch to deployed system.

You're not just a leader—you’re a builder. You love writing software, prototyping ideas, and using AI tools across every part of the development process.

Key Responsibilities

Strategic Technical Leadership

  • Act as the go-to AI technical expert in customer environments.
  • Drive discovery with senior technical stakeholders to identify high-impact AI opportunities.
  • Architect full-stack AI systems using LLMs, RAG pipelines, and robust evaluation frameworks.
  • Make informed decisions on model choice, fine-tuning, and deployment strategies.

AI System Development

  • Build production-grade prototypes with deep awareness of AI system limitations.
  • Apply deep knowledge of transformer architectures to real-world use cases.
  • Implement thoughtful evaluation systems to measure performance, bias, and business value.
  • Design with scalability and maintainability in mind from the very beginning.

Customer AI Enablement

  • Facilitate workshops to align AI strategy and implementation plans.
  • Lead assessments of AI readiness and architecture design.
  • Handle complex objections with calm, confident technical insight.
  • Build lasting partnerships that position the consultancy as the trusted AI integrator.

Internal Capability Building

  • Mentor engineers and upskill teams across the organisation.
  • Contribute to reusable components, design patterns, and shared best practices.
  • Lead internal discussions on the latest GenAI tools and trends.
  • Define quality benchmarks for how we design, implement, and evaluate AI systems.

What We’re Looking For

GenAI Mastery

  • Deep experience with transformer-based models and GenAI pipelines.
  • Strong understanding of prompt engineering, model finetuning, and toolchain integration.
  • Hands-on experience with top GenAI tools (ChatGPT, Claude, Copilot, Cursor).
  • Ability to build AI systems that are measurable, explainable, and responsibly deployed.
  • Bonus: Comfort combining classical ML techniques (clustering, classification, embeddings) with GenAI.

Engineering Leadership

  • 8+ years building scalable, maintainable, enterprise-grade software.
  • Comfortable leading architecture decisions and full-stack implementation.
  • Proven track record of delivering systems that make it to production—and work at scale.
  • Ability to guide and mentor engineering teams in fast-moving environments.

Customer-Facing Expertise

  • Experience working directly with senior stakeholders, including C-level decision-makers.
  • Skilled at navigating complex client environments and building long-term technical trust.
  • Comfortable leading workshops, aligning priorities, and facilitating technical strategy.
  • Known for being calm, clear, and credible in challenging or high-pressure settings.
