About the role

Key responsibilities & impact

You’ll join our Delivery function as a Forward Deployed Engineer, owning technical execution across battery-focused customer and partner workstreams.
You’ll work at the intersection of battery materials, manufacturing, microstructure, and AI - turning real datasets into engineering intelligence, helping customers make better engineering decisions, and feeding high-signal learnings back into the Polaron product.
Pre-Sale Development: and deliver polished technical demos showcasing platform capabilities. Assist sales teams by scoping opportunities and preparing proposals. Perform bespoke analysis as part of closing contracts.
Post-Sale Delivery: high-quality onboarding to ensure seamless adoption. Support on delivering pilot programmes, including project management and technical delivery. Support with customer retention - feedback sessions, gathering insights, bespoke development, and direct support.
Collaboration & Representation: Act as the bridge between customers and internal teams, influencing product roadmaps. Represent Polaron at industry events and creating thought leadership content, strengthening our position as a leader in materials innovation.
Battery Workstream Ownership: Own end-to-end delivery of battery microstructure analyses: from scoping and data readiness through to validated results and stakeholder-ready readouts. Lead technical workstreams within the battery programme, including leading a major grant project.

Requirements

What you’ll need

Battery domain depth (cell + materials): Strong understanding of how cathode material properties and microstructure connect to cell performance and failure modes, and how to reason about trade-offs in electrode and cell design. Masters degree minimum.
Microstructure + microscopy fluency: Comfortable working with SEM and microstructure data, spotting when imaging is insufficient, and driving an iterative loop with partners to get usable data and benchmarks.
Project delivery experience in a multi-partner consortium: Able to translate project goals into concrete workstreams, milestones, and success metrics, and drive execution with minimal oversight.
2+ years battery industry experience: or equivalent technical industrial experience.
Bonus points for:
Electrochemical modelling literacy: Comfortable interfacing with modelling teams, understanding parameterisation challenges, and using tools like PyBaMM enough to diagnose issues and unblock progress.
Manufacturing and process constraints awareness: Experience with electrode processing and manufacturability constraints.
Startup/entreprenurial mindset: Demonstrated high-agency and bias-to-action.
