Responsibilities

The Junior Pre Sales Engineer role is primarily focused on the technical delivery of Proofs of Value (PoVs). Success is measured by the ability to execute reliable, credible PoVs using real customer data, producing outputs that can be confidently used in live sales cycles to support deal progression and conversion.
The role initially involves limited direct customer exposure. Over time, progression comes through demonstrated technical judgement, curiosity, and a growing understanding of how high-quality technical execution drives commercial outcomes.
Own and deliver the technical execution of Proofs of Value (PoVs) to support the Chattermill sales cycle, from initial setup through to delivery.
Prepare, ingest, and transform customer data for PoVs, including data acquisition, ETL processes, data modelling, and validation.
Build and maintain PoV outputs such as dashboards, analyses, and reports, aligned to agreed scope, success criteria, and customer use cases.
Validate data quality, coverage, and assumptions to ensure PoV outputs are reliable, defensible, and fit for use in a commercial sales context.
Clearly document PoV setup, data limitations, and technical decisions to support internal handover, reuse, and consistency.
Collaborate closely with DataOps, MLOps, Sales, and Product teams to deliver PoVs efficiently and to an agreed quality standard.
Maintain demo and PoV environments in line with product releases, platform capabilities, and best practices.
As you grow in the Pre-Sales Engineer role, you will:
Gradually contribute to customer facing activities such as technical Q&A, PoV presentations, and solution scoping, supported by training and coaching.
Develop proactive technical judgement, anticipating data quality or coverage issues that could impact prospect confidence.
Connect technical decisions to customer use cases and intended outcomes.
Show curiosity beyond execution, understanding why data matters and how insights will be interpreted.
Contribute to shaping PoV scope around high-value use cases in partnership with Sales and Solutions Consultants.
