Staff Software Engineer – Buenos Aires, Argentina (Hybrid)

About Us

Nu is one of the largest digital financial platforms in the world, with more than 127 million customers across Brazil, Mexico, and Colombia. Guided by our mission to fight complexity and empower people, we are redefining financial services in Latin America and this is still just the beginning of the purple future we're building.

Listed on the New York Stock Exchange (NYSE: NU), we combine proprietary technology, data intelligence, and an efficient operating model to deliver financial products that are simple, accessible, and human. Our impact has been recognized by global rankings such as Time 100 Companies, Fast Company’s Most Innovative Companies, and Forbes World’s Best Bank. Visit our institutional page  https://international.nubank.com.br/careers/.

About the role

Our Engineering team helps Nu create and scale the technology that powers the best financial products in Latin America. We strive for state-of-the-art software development practices, using a variety of technologies and architectures to build resilient, secure, and highly scalable systems.

As a Staff Software Engineer, you will play a key role in shaping the technical direction of multiple teams, driving the design and evolution of large-scale distributed systems that serve millions of customers. While we value experience with our tech stack, we are confident that engineers who are eager to learn will be successful here — and we will teach you Clojure as our main backend language.

You will build and evolve:

• Horizontally scalable microservices written mostly in Clojure, using Finagle and leveraging functional programming techniques and hexagonal architecture
• High-throughput jobs and inter-service communication using Kafka
• Continuous Integration and Deployment pipelines on AWS
• Data storage solutions using Datomic and DynamoDB
• Monitoring and observability with Prometheus
• Services running as much as possible in Kubernetes

We are a process-light organization that values human interactions. We work in small, independent teams that feel like startups within the company and avoid unnecessary coupling and centralization whenever realistic. We understand that execution is key to success and continuously optimize our processes to remove bottlenecks.

You'll be responsible for

• Working with large-scale distributed systems and understanding their broad architecture and trade-offs
• Setting technical direction for multiple teams, ensuring alignment with Business Areas and architecture strategies
• Driving pragmatic innovation while ensuring resilient, secure, and flexible solutions that scale across products and geographies
• Mentoring engineers across teams and helping maintain a high technical bar organization-wide
• Writing, testing, instrumenting, documenting, and maintaining high-quality code
• Pairing and participating in code reviews to support the growth of others in and around your teams
• Collaborating closely with Product, Design, and Engineering leaders to build new end-to-end experiences
• Ensuring comprehensive observability, performance monitoring, and robust error handling across team services
• Participating in on-call rotations for your team and responding to incidents as necessary
• Focusing primarily on backend applications, while being open to contributing to mobile and frontend development according to business needs

We are looking for a person who has

• At least 8 years of experience developing digital products in complex environments
• Deep expertise in distributed systems, microservices architecture, and cloud technologies
• A proven track record of designing and delivering large-scale systems that serve thousands or millions of users
• A strong background in object-oriented or functional programming languages, with the ability to work across multiple languages
• Demonstrated ability to lead technical initiatives across multiple teams, even without direct authority
• Experience mentoring senior engineers and raising the technical bar across organizations
• Practical knowledge of agile software development methodologies and prior experience with CI/CD
• Strong communication skills to identify and prevent risks, and explain trade-offs clearly to both technical and non-technical stakeholders
• Advanced English skills

Our AI-powered Customer Data Cloud,  built on multi-patented technology, enables more than 400 global brands, including Alaska Airlines, Wyndham Hotels & Resorts, and DICK’S Sporting Goods, to turn customer data into a competitive advantage.

We unlock the full value of customer data with simplicity and speed. AI is at the core of our platform and the way we work — from powering advanced identity resolution and predictive analytics to streamlining internal workflows and decision-making. It’s not just a capability; it’s part of our DNA.

Our team thrives on curiosity, collaboration, and transparency, fostering a culture where everyone can contribute, learn, and grow. We welcome talented individuals from diverse backgrounds to help us remove data bottlenecks, accelerate business impact, and push the boundaries of what AI can do for the world’s most innovative companies.

With offices in Seattle, New York City, London, Melbourne and a growing presence in Argentina, you’ll join a fast-growing team tackling critical challenges at the intersection of AI, data, and customer experience. Ready to make an impact? Let’s talk.

The Role

At Amperity, engineers work in small, collaborative feature teams. As an SDE IV, you'll contribute across teams that move quickly, embracing rapid, iterative development to solve meaningful customer problems and improve the platform. Engineers are involved in shaping what we build and how we build it, working with Product, Support, Customer Success, and Go-to-Market teams to create high-impact features and seamless customer experiences. We keep our processes lightweight, our communication clear, and our focus on delivering value.

As one of the first teammates building our footprint in Argentina, you’ll play a meaningful role in our growth and be part of shaping this new chapter from the beginning. 

Interesting Problems

• Ingest and understand large amounts of structured customer, product, and event data
• Create probabilistic knowledge graphs by training ML models to unify this data across different systems
• Take research algorithms and realize them in production for extremely high-scale usage
• Build visual experiences and toolset to help users visualize their data, understand their customers and surface the most impactful insights
• Integrate our system into the operating core of the businesses we serve
• Automate the management of thousands of VMs running data processing jobs

About You

• 12+ years industry experience working in SaaS and distributed systems environments
• Experience working with large-scale data-oriented systems on a major cloud provider

• You can guide architectural decisions on your team and across teams with an eye to high-level tradeoffs, and know when and how to explore novel approaches. You are a backstop for oncall issues on your team.
• Passionate about building scalable infrastructure systems for both internal and external customers
• Excited about using functional languages (like Clojure!) in a production environment - Clojure or functional language experience isn't required
• You educate those outside your team on your team's technology and products. You mentor those on your team and contribute to their growth. You take opportunities to share your unique talents and interests across the whole engineering team in the form of tools, education, excellence in interviewing, onboarding, or leading various special interest groups
