Role
Who you are
- The ideal candidate has led and delivered large-scale ML/AI projects to production with real business impact, shaped technical direction, and built strong teams
- 7+ years in ML engineering, including 2 years leading technical direction of teams (formal people management is a plus)
- Master’s in Computer Science, Statistics, Mathematics, or a related field
- Experience with recommender systems at scale: retrieval and candidate generation, ranking models, and real-time personalization in high-load production environments
- A track record of building and operating ML/AI systems in production, across the full lifecycle: feature engineering, model development, deployment and monitoring
- Strong systems, architecture and MLOps background: distributed, event-driven ML systems, API and model serving as microservices, containerization and orchestration with Kubernetes / AKS, and CI/CD and experiment tracking
- Strong grounding in experimentation and statistics: metric design, A/B testing and causal inference to quantify business impact
- Expertise in Python and PySpark, with a solid grasp of ML algorithms and frameworks (MLlib, Scikit-learn, TensorFlow/PyTorch, MLflow). Familiarity with a language such as Java or Kotlin is a plus
- Experience in building AI agents and LLM-based products in production, including memory, context engineering, retrieval and orchestration, and multimodal retrieval systems/architecture
- Comfortable splitting your time between building directly and leading, and happy to stay hands-on in the code and architecture
- Excellent communication skills, able to explain complex technical choices and trade-offs to non-technical stakeholders
What the job involves
- We are looking for a Lead Machine Learning Engineer to head up our ML & AI team and the platform behind it, in a role that is equal parts hands-on and leadership
- Own the architecture of our ML & AI systems end to end: data pipelines, feature and model stores, training and serving infrastructure, built as reusable capabilities our auction brands can share
- Design the architecture and orchestration of our AI agents platform, with strong evaluation, monitoring and guardrails for reliable behaviour in production
- Strengthen and contribute to our existing MLOps setup: automated training, validation, deployment and monitoring, experiment tracking and CI/CD
- Design and build our recommendation, search and ranking systems end to end: candidate generation and retrieval, ranking models, embeddings and vector search, and real-time personalization at scale
- Deploy models as robust APIs and scalable microservices, containerized and orchestrated with Kubernetes
- Design systems, write and review code in a modern stack, and raise the bar on engineering best practices
- Identify and prioritize the highest-impact opportunities across our auction brands and landscape, set and own the ML & AI roadmap
- Frame business problems as ML tasks, define most impactful business metrics, and run rigorous experiments (A/B tests) to measure real impact
- Drive continuous, incremental improvement of our ML & AI products, balancing near-term delivery with longer-term investment in the platform and innovation
- Work closely with product managers and other tech leads to align priorities and delivery across teams
- Manage business stakeholders and align them on priorities, scope and trade-offs, translating complex technical concepts to non-technical audiences effectively
- Lead, mentor, hire and grow a team of ML engineers, supporting their career development and upskilling, and ensure chapter growth
Application process
- We usually respond within a week
Our take
To support more sustainable trade, TBAuctions supplies an auction platform specifically for used B2B goods. The company's online intelligent auctions use a proprietary cross-border platform (ATLAS) to connect buyers and sellers, offering a seamless self-serve experience.
A feature of TBAuction's tech is that it is able to balance demand and supply, creating a robust marketplace that can best serve traders on both sides. Millions of products are auctioned through the platform every year, a testament to the value of TBA's offering.
Now pursuing global expansion, the company acquired industrial auctioneer Surplex. This move will support growth in numerous countries including Spain, Poland, Portugal and Romania. It also bolsters TBAuctions' presence in Germany, France and Italy, adding deep expertise in metal and woodworking.
