Customer Success Engineer, UK (remote)

About the Role
We’re hiring a Customer Success Engineer to support and expand some of our most strategic enterprise customers. This role is deeply technical and hands-on — you will serve as the engineering-adjacent partner responsible for ensuring customers successfully integrate with and scale on Nash’s platform. From solution design to deployment to ongoing optimization, you’ll guide customer teams through every stage of their technical journey.

As part of the Customer Success organization, you will combine systems expertise, analytical problem-solving, and customer partnership to deliver measurable outcomes. You will help customers architect workflows, debug integration issues, improve performance, and use Nash to its fullest potential. You are the technical backbone of the account — the person customers trust to get it right.

• Serve as the technical owner for enterprise customer accounts — accountable for integration success, system performance, and technical adoption.

• Work closely with customer engineers and product teams to design, implement, and scale solutions on Nash’s platform.

• Become a platform expert capable of diagnosing issues, advising on best practices, and guiding architectural decisions.

• Troubleshoot API issues, workflow failures, data mismatches, and other system-level challenges across customer and Nash environments.

• Analyze operational and technical KPIs to identify root causes, improve performance, and reduce defects.

• Provide structured, actionable feedback to Nash product and engineering based on real-world customer usage.

• Support account growth by ensuring customers successfully deploy new capabilities and expand usage over time.

• Act as the internal technical advocate for your accounts during roadmap discussions and cross-functional initiatives.

• 5+ years in a technical customer-facing role such as Solutions Engineer, Customer Success Engineer, Forward Deployed Engineer/PM, TAM, or similar.

• Hands-on experience with APIs, integrations, logs, and data flows; strong debugging instincts.

• Proven success supporting enterprise customers through complex technical deployments.

• Ability to translate technical details into actionable guidance for both engineering and non-technical stakeholders.

• Strong analytical and problem-solving skills with comfort navigating ambiguous systems.

• Demonstrated capability to quickly master a complex platform and use that knowledge to guide customer outcomes.

• Excellent communication skills with confidence interfacing at multiple levels of customer organizations.

• Experience in logistics, supply chain, or other operationally intensive SaaS systems.

• Background in high-growth startups or enterprise retail integrations.

• Familiarity with modern engineering tooling, observability tools, workflow engines, or API ecosystems.

• Experience in consultative roles blending technical depth and customer outcome ownership.

More about Nash

Commerce has inverted. For decades, customers came to where products and services were. Now products and services come to them, on their terms, in real time. That shift has turned every company into a logistics company, even though almost none of them were built to be one. Couriers, fleets, gig workers, parcel carriers, in-store labor, and increasingly autonomous systems all have to be coordinated in real time, against tighter windows and rising expectations, with hard-fought customer trust on the line.

Nash unifies decisioning, execution, and capacity into a single programmable platform. Real-time, AI-native intelligence determines what should happen, operational control executes it, and the platform dynamically orchestrates capacity from any source: a company's own fleets, partners, or the Nash delivery network. Whether a job involves a courier, a gig driver, an internal fleet, a store employee, a technician, or an autonomous vehicle, Nash selects the right resource and manages execution through completion.

We power delivery and logistics for some of the most recognizable brands in commerce, including Walmart, Urban Outfitters, 7-Eleven, and Woolworths, alongside platforms like Shopify and Toast. Over the next decade, logistics will become as foundational to commerce as payments, cloud, and connectivity. Nash is the platform that powers it.

Nash was founded in 2021 by Mahmoud Ghulman (2x Founder, MIT) and Aziz Alghunaim (2x Founder, 2x YC, Ex-Palantir, MIT) and is backed by Y Combinator, a16z, and other top investors. We are headquartered in San Francisco.
