We’re Making Travel Effortless. Join Us.
Travel is essential, whether it’s visiting family, starting a new adventure, or taking a career defining trip. Yet today, over 4 billion airline passengers rely on tech that hasn't changed in decades.
At Duffel, we’re rebuilding the infrastructure underpinning the global travel industry. Backed by top-tier investors (Benchmark, Blossom, Index Ventures, and Kima Ventures) and born out of Y Combinator (S18), we’re simplifying complex systems to build the future of travel.
About the role
This role crosses the boundary between Solution Engineering and Customer Success Engineering.
You'll partner with customers from the earliest discovery conversations through implementation and beyond, becoming their long-term technical counterpart as they build and grow on Duffel.
Working closely with Enterprise Account Executives, you'll lead technical discovery, shape solution architecture, run workshops and guide customers through complex technical decisions. Once a partnership is in place, you'll continue supporting their technical strategy as they launch new products, expand into new markets and scale their integrations.
You'll collaborate daily with Product, Engineering, Implementation, Customer Success and Technical Support, ensuring the solutions we design are practical, scalable and create long-term value for our partners.
If you enjoy solving complex technical problems, building trusted customer relationships and influencing both product direction and commercial success, we'd love to hear from you.
What you'll be doing
Partner with Enterprise Account Executives throughout the sales process, leading technical discovery and solution design.
Understand customer goals, technical environments and product requirements to design scalable solutions using Duffel's APIs.
Lead architecture discussions, technical workshops, product demonstrations and proof-of-concepts.
Become a trusted advisor to engineering teams, product leaders and technical decision makers.
Remain accountable for the integrity of the technical solution throughout implementation. Partner with an Implementation Manager, who owns the delivery programme, while you own the architecture and important solution decisions.
Advise customers on best practices around integrations, scalability, reliability and user experience.
Translate partner needs into clear problem statements and evidence for Product and Engineering, distinguishing one-off requests from recurring needs that should influence Duffel’s product strategy.
Work alongside Implementation Managers, Partner Managers and Technical Support to deliver a seamless customer experience.
Create reusable technical documentation, reference architectures and best practices that help us scale the Partner Engineering function.
We're looking for someone who
Has significant experience leading technical work with large or complex enterprise customers in roles such as Solutions Engineer, Partner Engineer, Customer Success Engineer, Solutions Architect, or Sales Engineer.
Enjoys working directly with customers to understand complex technical challenges and design thoughtful solutions.
Has a strong understanding of REST APIs, webhooks, authentication, integrations and modern software architecture.
Is capable of investigating complex integration behaviour and significant technical risks when needed, while partnering with Technical Support Engineering, which owns routine questions and incidents.
Can confidently communicate with software engineers, product managers and senior technical stakeholders.
Balances technical excellence with commercial awareness, understanding how technology helps customers achieve business outcomes.
Thrives in collaborative environments, working closely across Sales, Product, Engineering and Customer Success.
Enjoys ambiguity, takes ownership and is excited to help build new ways of working as Duffel continues to grow.

API-first or developer platform businesses.
Enterprise SaaS or B2B infrastructure products.
Fintech, payments, commerce or travel technology.
Building integrations or technical solutions for enterprise customers.
Supporting customers through complex implementation or onboarding projects.
Helping establish or scale a Solutions Engineering or Partner Engineering function.
