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.

Last mile is a $500B industry powering digital commerce but managed largely with self managed API integrations. Nash approaches last mile orchestration with information completeness solutions from checkout, courier management, customer engagement, and post-purchase experience. Doing this enables merchants and customers to capture immense efficiencies, drive better customer experience, reliability and business outcomes.

We are working towards a mission of processing a double digit percentage of every physical last-mile transaction. We achieve this by providing top of the market modules for each step of the customer journey and leveraging the network effects from having more information that allows traditional competitors to collaborate. It’s a big mission, but we are already seeing strong market pull as we are already serving some of the largest retailers in the world like Walmart, 7-Eleven and Woolworths.

Nash was founded in 2021 by Mahmoud Ghulman (2x Founder, MIT) and Aziz Alghunaim (2x Founder, 2x YC, Ex-Palantir, MIT) and has raised funding from top investors, including Y-Combinator and a16z, to build the world’s best logistics infrastructure platform. We are based in SF.
