Sales Engineer \\ Commercial Engineer in England

Location: Hybrid - London

Department: Sales

Tightly is about empowering omnichannel brands to master their inventory—and their cash flow. We are the Inventory Planning & Purchasing Intelligence Platform built for the complexity of modern commerce. With a culture that is all-in on impact, innovation, and customer obsession, Tightly is the sweet spot for building big, moving fast, and taking supply chain technology—and your career—to the next level.

In this role, you will be the technical engine behind our sales process. You don't need to come in as a retail expert—we will teach you the intricacies of the supply chain. What we need from you is the technical intuition to navigate data challenges and the confidence to guide customers through critical Pilots and Proofs of Concept (PoCs).

Tightly sits as the intelligence layer on top of a merchant's ERP and sales channels. Your job is to ensure that the data translation is flawless. You will work with prospective customers to validate their inputs, using your technical toolkit (SQL, Python, AI) to troubleshoot anomalies and ensure that the purchasing plans Tightly generates are based on accurate, clean signals.

• Lead Technical Pilots & PoCs: Own the most critical phase of the sales cycle. You will guide the prospect through the data ingestion process, ensuring the Tightly platform accurately models their business logic before the deal is closed.
• Bridge the Data Gap: While our platform handles the heavy lifting, you will use your technical skills (SQL, Python) to troubleshoot edge cases. If a customer's data format doesn't match the system of record, you find the fix to unblock the deal.
• You will use modern tools like Claude and Gemini to write quick scripts, debug data errors, or analyze file structures, allowing you to move faster than a traditional engineer.
• You will explain to stakeholders how Tightly interprets their historical data to create a reliable forecast, giving them the confidence to trust our recommendations.
• Master the Domain: We will teach you retail. You will learn how global brands decide what to buy, how they manage capital efficiency, and how to model purchasing constraints.
• Technical Fluency (SQL & Python): You aren’t building the product, but you know how to interrogate data. If a customer’s export is messy, you can write a quick script or query to diagnose the issue and fix it rather than waiting for Engineering.
• When a Pilot data set looks "off," you have the curiosity to dig in, find the discrepancy, and resolve it using the tools at your disposal.
• Customer-Facing Comfort: You are comfortable presenting on Zoom, managing a room, and translating technical data concepts into business value for non-technical humans.
• AI Literacy: You are comfortable using LLMs to speed up your own workflows, whether that’s formatting data or drafting technical responses.
• The Science of Inventory Planning: We don’t expect you to know "Open-to-Buy" formulas or supply chain constraints on Day 1. Our team works to ensure that the intelligence we provide is accessible, usable, and mathematically sound.

Every Tightly employee is expected to follow the company’s confidentiality and security standards for handling sensitive merchant data. Tightly is growing fast, and we’re scaling our team to help enable and accelerate our growth. We are looking for people who share our values, challenge ordinary thinking, and push the pace of innovation while building a future for themselves and Tightly.
