# Senior Software Engineer (Lending Team)

**SumUp** — São Paulo, São Paulo, Brazil

Apply: https://sumup.com/careers/positions/8769169002?gh_jid=8769169002

## About SumUp

## About the role

At **SumUp**, we believe small merchants are the heartbeat of our communities. By joining the **Lending** **tribe**, you'll help launch a new financing product designed for the roughly 50 million registered and informal sole traders in Brazil who currently can't access affordable credit.

As a **Senior Software Engineer**, you'll be the technical anchor of a brand new squad, operating with real autonomy. This is a role for someone who's energised by ambiguity, comfortable owning hard decisions without a playbook to follow, and excited to help shape a lending product from the ground up in a fast-moving, regulated market.

---

##### What you'll do

- Build the onboarding journey: Design and build the onboarding experience for non SumUp customers, including KYC and Open Finance account and income data integration

- Own the repayment integration: Lead the technical relationship with our Open Finance partner alongside the Bank squad

- Deliver the product end to end: Build the core lending product experience, from credit assessment through to servicing and collections

- Power the credit decisioning: Connect Open Finance data to underwriting models to support fast, reliable credit decisions

- Set the technical direction: Make high impact architecture calls with minimal guidance, and coach mid level and entry level engineers

- Navigate the regulatory landscape: Partner closely with the Bank squad, Compliance, and our Open Finance external integration partner on Open Finance requirements in Brazil

---

**What makes you a great fit**

- Have experience designing and owning complex distributed systems end to end, ideally backed by around 6 years in software engineering

- Have strong knowledge of Open Finance or Open Banking integrations, gained from working inside a bank, fintech, or another regulated financial product

- Feel comfortable working in Golang on backend systems, with the flexibility to work confidently in another language such as Java, Kotlin, Python, or Ruby

- Can identify gaps and ambiguity early, weigh up tradeoffs, and drive decisions without waiting for perfect information

- Shares excitement about building a new product from scratch and exploring unfamiliar territory rather than maintaining something established
