About the Company

About Stripe

Stripe is a financial infrastructure platform for businesses. Millions of companies - from the world's largest enterprises to the most ambitious startups - use Stripe to accept payments, grow their revenue, and accelerate new business opportunities. Our mission is to increase the GDP of the internet, and we have a staggering amount of work ahead. That means you have an unprecedented opportunity to put the global economy within everyone's reach while doing the most important work of your career.

About the team

The UI Platform team, known as Sail, builds the foundations that support Stripe's Dashboard and many of Stripe's other user interfaces. The Sail Services team provides backend-for-frontend services that help product teams build consistent, scalable user experiences.

The team is defining its mission, roadmap, and technical vision as the UI platform takes on a more central role in how Stripe builds user interfaces. We work with engineers, product managers, and designers across Stripe to connect the design system, software development kits, and backend services into a consistent, surprisingly delightful user experience.

Key Responsibilities

As a Staff Software Engineer on the UI Platform team, you'll help shape the technical direction for the services that support Stripe's user interfaces. You'll combine hands-on engineering with technical leadership, working with backend engineers and cross-functional partners to deliver platform capabilities that help Stripe build consistent, reliable user experiences.

  • Define a cross-team technical strategy, architecture, and multi-year roadmap for the backend services that power Stripe's merchant-facing experiences
  • Lead the design and delivery of scalable backend services that give product teams a consistent foundation for building reliable user experiences across the Dashboard, mobile applications, and other interfaces
  • Build reusable platform capabilities that help product teams develop, operate, and improve their products with confidence
  • Partner with engineers, product managers, and designers to connect the design system, software development kits, APIs, and backend services
  • Provide hands-on technical leadership through architecture reviews, technical guidance, and mentorship, raising the quality and effectiveness of the team's work

Candidate Profile & Mindset

We're looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply. The preferred qualifications are a bonus, not a requirement.

Minimum requirements

  • This is a staff-level role, which typically means 10+ years of experience building complex, reliable, scalable APIs or distributed systems
  • Track record of leading the technical design and delivery of large projects across multiple engineering teams
  • Experience setting technical direction and translating strategy into an executable roadmap
  • Demonstrated ability to communicate technical decisions and tradeoffs with engineering, cross-functional partners, and senior leadership

Preferred / Nice-to-Have Qualifications

  • Experience building backend-for-frontend systems or frontend platform services
  • Experience working on developer platforms, design systems, or UI infrastructure
  • Experience using agentic development workflows to improve engineering productivity
  • Experience with feature flagging, experimentation, telemetry, or analytics systems

In-office expectations

Office-assigned Stripes in most of our locations are currently expected to spend at least 50% of the time in a given month in their local office or with users. This expectation may vary depending on role, team and location. For example, Stripes in Stripe Delivery Center roles in Mexico City, Mexico, Bengaluru, India, and Dublin, Ireland work 100% from the office. Also, some teams have greater in-office attendance requirements, to appropriately support our users and workflows, which the hiring manager will discuss. This approach helps strike a balance between bringing people together for in-person collaboration and learning from each other, while supporting flexibility when possible.

Pay and benefits

The annual salary range for this role in the primary location is €105,600 - €158,400. This range may change if you are hired in another location. For sales roles, the range provided is the role's On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role. This salary range may be inclusive of several career levels at Stripe and will be narrowed during the interview process based on a number of factors, including the candidate's experience, qualifications, and specific location. Applicants interested in this role and who are not located in the primary location may request the annual salary range for their location during the interview process.

Specific benefits and details about what compensation is included in the salary range listed above will vary depending on the applicant's location and can be discussed in more detail during the interview process. Benefits/additional compensation for this role may include: equity, company bonus or sales commissions/bonuses; retirement plans; health benefits; and wellness stipends.

We look forward to hearing from you.

At Stripe, we're looking for people with passion, grit, and integrity. You're encouraged to apply even if your experience doesn't precisely match the job description. Your skills and passion will stand out - and set you apart - especially if your career has taken some extraordinary twists and turns. At Stripe, we welcome diverse perspectives and people who think rigorously and aren't afraid to challenge assumptions. Join us.
