Lead Full Stack Engineer

About The Company

Founders today are building global companies from day one — but the systems that manage their money were built for a different era. Aspire exists to change that!

We’re building the financial operating system for global founders, bringing banking, software, and automation into a single platform so businesses can move faster across borders and stay focused on building.

Aspire is built by people who think from first principles, care deeply about solving hard problems, and take real ownership of their work. Our team brings global experience from leading fintech and technology companies, and many of us are former founders and operators who understand what it takes to build thoughtfully, make trade-offs, and deliver at scale in a global environment.

Backed by leading global investors including Y Combinator, Peak XV, and Lightspeed, Aspire has been trusted by more than 50,000 startups and growing businesses worldwide to manage their finances since 2018. Together with partners like J.P. Morgan, Visa, and Wise, we’re building for the next generation of global companies.

About The Role

What you'll do:

Customer first, always

• Find and remove friction across key customer journeys on web and mobile, from onboarding to day-to-day usage
• Use support tickets, contact drivers, app reviews and product analytics to decide what to fix next
• Build self-service capabilities that let customers resolve issues without contacting support
• Own and evolve the customer support AI bot: improve answer quality and resolution rate, connect it to product data and actions, and hand off smoothly to human agents when needed
• Treat bugs and incidents through the customer's eyes: fix the root cause, not only the symptom

Build

• Write production code across frontend and backend, spending around 80% of your time hands-on
• Own technical design for the squad's work and set a high bar for quality, performance and reliability
• Instrument every change so we can measure its impact on customer behaviour and contact rate
• Run experiments and A/B tests to validate improvements before scaling them

Lead

• Lead, coach and grow a squad of 2 engineers, and help hire as the team grows
• Work with the Product Manager and Designer to shape the roadmap and turn problems into shippable increments
• Partner with engineering teams across Aspire to land changes in code your squad does not own
• Work closely with Customer Support and Operations to understand pain points and close the feedback loop

What We're Looking For

• 7+ years of software engineering experience, including 2+ years leading engineers as a tech lead
• Strong, recent hands-on experience on both frontend (e.g. React, TypeScript) and backend (APIs, services, databases)
• A genuine obsession with customer experience: you notice friction, care about the details and use the product yourself
• A track record of shipping improvements that moved a customer metric, and you can explain how you measured it
• Experience working across team boundaries in a multi-team engineering organisation, influencing without authority
• Good product sense: you can push back, propose simpler solutions and trade off scope against impact
• Comfortable with data: you can read dashboards, define events and query data to answer your own questions
• Clear written and verbal communication with both technical and non-technical stakeholders

Nice To Have

• Experience in fintech, banking or another regulated industry where security and compliance shape the product
• Mobile development experience (e.g. React Native)
• Built self-service or support tooling: help centres, in-app guidance, chatbots or AI-assisted support
• Hands-on with product analytics and observability tools (e.g. Mixpanel, PostHog, Sentry, Datadog)
• Experience with accessibility, web performance and front-end design systems
• Worked in a B2B or SME-focused product across multiple markets

How We'll Measure Success

In your first 90 days

• You know the top customer contact drivers and the journeys behind them
• You have shipped at least one measurable friction fix end to end
• You have working relationships with the engineering teams that own our most critical flows

Over time

• Contact rate goes down and self-service and AI bot resolution rates go up
• Customer satisfaction (CSAT/NPS) and app store ratings improve
• Retention improves in the journeys the squad has worked on
• The squad ships predictably, with high quality and few regressions
