Purpose of the Role Enterprise Discovery customers increasingly require hands-on customisation beyond standard product configuration. The Machine Learning Customer Engineer is a dedicated, customer-embedded engineering role designed to own the full spectrum of technical customisation for our top-tier accounts. You will bridge the gap between post-sales support and core product engineering, serving as a technical "special forces" operative who translates complex business requirements into tangible code and system optimisations. The Customisation Spectrum The FDE is purpose-built to own Levels 1–5 of the customisation spectrum, ensuring that core R&D remains focused on next-generation platform development: Education : Platform training, feature evangelism, and root-cause explanation. Configuration: Dashboard, integration, and algorithm configuration changes. Surgical Tweaks: Customer-specific process changes and deep data analysis. Custom Code: Conversational agents, platform extensions, and feature customization. Escalation: Identifying major product changes for Core Engineering cycles. Key Responsibilities Account Ownership: Maintain ongoing technical ownership of 2–3 high-value enterprise accounts; this is not a rotational assignment. Technical Implementation: Build and deploy conversational agents, custom extensions, and algorithmic tweaks to solve specific business problems. Data-Driven Validation: Use A/B testing and deep data analysis to validate the impact of technical changes on customer KPIs. On-Site Collaboration: Travel to customer sites (EMEA/AMER) to lead technical workshops and deeply understand their architectural constraints. Feedback Loop: Act as a critical bridge to R&D, identifying recurring customization needs that should be productized in the core platform. Candidate Profile We are looking for a unique blend of high-level engineering talent and strategic business acumen: The Mix: 50% Programmer · 30% Product Acumen · 20% Soft Skills & Problem Solving. Search Specialist: Deep knowledge of search internals, including ranking models, catalog configuration, relevance, recall, and personalization. Technical Generalist: Fluent enough in code to make minor to moderate changes to support testing and custom extensions. Consultative Mindset: Ability to translate nebulous business goals into specific technical solutions and communicate those to stakeholders. Requirements Experience: Proven track record in Search Engineering, Machine Learning Engineering, or high-end Technical Delivery. Product Knowledge: Deep understanding of Discovery platforms and how ranking/algorithms impact e-commerce performance. Soft Skills: Exceptional communication skills with the ability to navigate complex enterprise environments. Mobility: Willingness to travel internationally to engage with customers in their own environments. #LI-HO1 More things you'll like about Bloomreach: Culture: A great deal of freedom and trust.
