Technical Customer Success Manager, UK (remote)

About the Role

We’re hiring a Technical Customer Success Manager to own and grow some of our most strategic enterprise accounts. This is not a temporary or project-based role—you are the long-term owner of the customer relationship, accountable for adoption, performance, and ongoing outcomes. Acting as an embedded partner, you will work directly with customer product, engineering, and operations teams to design, deploy, and continually optimize solutions on Nash’s platform.

This role sits within our Customer Success organization and blends strategic account leadership with hands-on technical problem solving. You will drive adoption, reduce defects, improve operational performance, and ensure customers realize meaningful business impact. In short: you own the account, the results, and the success of the partnership.

Responsibilities

• Own enterprise customer accounts end-to-end — act as the single point of accountability for adoption, performance, and growth.

• Partner closely with customer product and engineering teams to design, deploy, and scale solutions on Nash’s platform.

• Become a true Nash expert — understand platform capabilities and limitations as well as anyone in the company.

• Use your expertise to advise customers, guide integrations, and identify improvement opportunities.

• Drive measurable outcomes across KPIs such as delivery performance, defect reduction, and cost efficiency.

• Lead account growth and retention by ensuring customers realize ongoing value and by surfacing new expansion opportunities.

• Troubleshoot and resolve integration or workflow challenges in collaboration with customer engineers and Nash’s internal teams.

• Act as the internal advocate for your accounts, ensuring their priorities are represented across cross-functional initiatives.

Qualifications (Must-Have)

• 5+ years in a customer-facing, technical role such as Technical CSM, Technical Account Manager, Solutions Engineer, Forward Deployed PM, or similar.

• Proven success owning enterprise customer relationships and driving adoption, performance, and growth.

• Strong technical fluency — comfortable with APIs, integrations, debugging workflows, and collaborating with engineering.

• Experience advising customer product/engineering leaders and translating technical concepts into business outcomes.

• Strong analytical and problem-solving skills with the ability to diagnose root causes in complex systems.

• Demonstrated ability to rapidly master a product and use that knowledge to guide customers and shape feedback.

• Excellent communication and executive-presence skills.

Nice-to-Have

• Experience in last-mile logistics, supply chain, or complex B2B SaaS systems.

• Experience in high-growth startups or enterprise retail environments.

• Familiarity with tooling such as Jira, API docs, observability platforms, or engineering workflows.

• Background in consultative roles involving both technical depth and commercial accountability.

More about Nash.AI

Nash is building the logistics infrastructure for the internet

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.
