AI/ML Engineer - freelancer

Overview

The AI/ML Engineer will build and continuously evolve shared AI capabilities, reusable services, and engineering accelerators for multiple construction software products. The role focuses on production-grade AI systems, evaluation-driven development, AI-native engineering practices, and cross-functional delivery from prototyping through production improvement.

What you'll do

• Build and continuously evolve shared AI capabilities, reusable services, and engineering accelerators adopted across multiple construction software products.
• Design and implement production-grade AI systems including LLM-based experiences, retrieval pipelines, tool use, orchestration layers, and agentic workflows.
• Create technical artifacts such as specifications, evaluations, interface definitions, and workflow contracts for human and machine execution.
• Define and apply evaluation-driven development loops covering quality, reliability, latency, cost, grounding, and other relevant performance dimensions.
• Partner with product teams to identify high-value cross-product opportunities, support integration of shared capabilities, and recommend patterns without owning product-specific architecture decisions.
• Contribute to AI-native engineering practices through Spec-Driven Development, AI-assisted development workflows, automated testing, and intelligent engineering agents.
• Apply standards and guardrails for AI reliability, observability, governance, security, and responsible production use of AI solutions delivered by the central team.
• Prototype and validate technical approaches, turning emerging AI capabilities into scalable building blocks with clear business relevance.
• Support and guide other engineers through technical collaboration, peer review, and knowledge sharing in modern AI engineering and experimentation.
• Work with AI PM / PO, engineering, and business stakeholders to align implementation choices with customer value, delivery feasibility, and measurable outcomes.

What you'll need

• At least 5+ years of hands-on software engineering experience, including significant work on production-grade AI or data-intensive systems in complex delivery environments.
• Excellent Python programming skills.
• Proficiency in Azure/AWS cloud platforms.
• Hands-on experience with Generative AI technologies and applications.
• Strong practical understanding of LLMs, retrieval-augmented generation, tool use, agents, and their real-world trade-offs, limitations, and failure modes.
• Experience designing and operating end-to-end AI systems across APIs, application services, data pipelines, retrieval layers, evaluation workflows, and cloud infrastructure.
• Ability to define measurable quality criteria and evaluation approaches for AI systems while balancing customer value with reliability, latency, cost, and maintainability.
• Practical experience with AI-assisted engineering, Spec-Driven Development, and modern developer tooling.
• Ability to improve how teams work by combining human judgment with automation and agent support.
• Strong architectural judgment and ability to design reusable patterns and shared capabilities while collaborating with product teams that own their local implementation decisions.
• Demonstrated track record of contributing to cross-functional work from early exploration and prototyping through production rollout and continuous improvement in agile environments.
• Ability to support and influence other engineers, raise technical standards through collaboration, and create clarity in ambiguous and fast-changing AI environments.
• Strong communication and collaboration skills, with the ability to translate technical complexity into decisions and actions for product, engineering, and business stakeholders.
• Adaptive mindset, high learning agility, and genuine openness to continuous change in a field shaped by rapid advances in AI.
• Master's degree in Computer Science, Software Engineering, Artificial Intelligence, or a related technical field; equivalent experience considered for exceptional candidates.
