About the team

Portfolio Solutions is the team within Nu Asset Management responsible for the firm's ETFs and systematic fundos, and the allocation models behind our products and the broader Nubank ecosystem. We believe most of an investor's long-term return comes down to three things: cost, allocation, and discipline. Our job is to deliver all three at scale — which means we treat infrastructure, automation, and AI tooling as core to investment research, not as side projects.

We're looking for a quantitative analyst to strengthen our research, index construction, allocation modeling, and the platform that ties it all together.

What you'll do

• Research, design, and implement indices and systematic strategies across fixed income, equities, and derivatives — including structures such as covered calls, duration barbells, and factor portfolios
• Build and maintain multi-asset allocation models, with attention to efficient replication, tracking error control, and transaction costs
• Run rigorous backtests: no look-ahead, no survivorship, realistic costs. We don't publish a curve without out-of-sample replication
• Help build the quantitative infrastructure of the team: reusable data pipelines, backtest frameworks, monitoring dashboards, and reporting workflows on Databricks. The goal is that every model you build outlives the project it was born in
• Develop AI-powered tools for investment research: LLM-driven analysts on top of our internal datasets, agents for routine analytical tasks, copilots that compress the distance between question and answer for the whole team
• Support the launch of new ETFs — from index methodology to interactions with index prodviders, market makers, administrators, and custodians
• Read papers, replicate results, and tell apart what works from what looks like it works

What we're looking for

• Bachelor's degree in a quantitative field: engineering, math, physics, statistics, economics, computer science, quantitative finance, or equivalent
• 3+ years in quantitative research, systematic asset management, risk, or adjacent roles 
• Strong Python (pandas, numpy, scipy). Comfort writing code that other people will read, run, and extend
• Curiosity about — and ideally experience with — building production-grade analytical infrastructure: pipelines, jobs, dashboards, internal tools
• Genuine interest in applying LLMs and AI agents to quantitative work, not just as users but as builders
• Familiarity with the Brazilian market: NTN-B, IMA, Ibovespa, B3 derivatives, local ETF dynamics
• A collaborative, constructive way of working: you ask for help when stuck, you offer help when others are, you document, you review code, you disagree clearly without making it personal, and you give credit generously
• Ability to communicate quantitative results clearly — to portfolio managers, commercial teams, and ultimately to the end investor

Nice to have

• CFA, CAIA, FRM, or a graduate degree in a quantitative field
• Experience with ETFs, index replication, or benchmark construction
• Hands-on Databricks (Workflows, Delta, Unity Catalog, Databricks Apps), version control discipline, MLOps fundamentals
• Experience designing or shipping internal tools, copilots, or RAG systems

Benefits

• Chance of earning equity at Nubank
• Food/ Meal Card (Vale-Refeição and/or Vale Alimentação)
• Public Transportation Commuting Benefit (Vale-Transporte)
• NuCare – Psychological, Financial and Legal Assistance Program
• Life Insurance
• Medical Plan
• Dental Plan
• NuLanguage – Language Course Program
• Nucleo - Our learning platform of courses
• Extended Parental Leave
• Daycare Allowance
• Parental Consultancy
• Work-from-home Allowance
• Gym Partnerships
• 30 days of paid vacation

About the role

As a Sr. Software Engineer on the QA Automation Tools team, you will drive initiatives that enable our QA and development teams to move faster and ship with greater confidence. Embedded with the development team,  you'll architect scalable automation solutions for a live multiplayer game where dynamic content — character customizations, ability interactions, and procedurally generated scenarios — creates a testing surface that requires adaptive, not static, strategies.

Agentic development is a core part of how this role operates, not an aspiration. You'll integrate AI-assisted workflows from day one, using coding agents to accelerate test creation, debugging, and code review while maintaining the engineering judgment to steer, verify, and override. You'll work directly with developers to influence how systems are built for testability, and communicate your decisions clearly enough that other engineers can carry the work forward.

What you’ll achieve

• Design adaptive test automation for dynamic game content — character customization, map scenarios, and procedurally generated content (PGC) — using approaches that stay valid as content evolves without requiring manual test plan rewrites
• Propose game engineering changes that improve testability: test hooks in generation tools, game data structures that support combinatorial testing, metadata that enables bot automation
• Integrate AI-assisted workflows into automation delivery end-to-end, from test scaffolding and debugging to code review and pipeline integration
• Integrate quality efforts throughout the development lifecycle, including automation frameworks, build pipelines, and performance metrics
• Set technical standards for the team's automation code, shape cross-project QA strategy, and share reusable patterns that let other engineers maintain quality as the team scales

What You’ll Need to Be Successful

• Proficiency in Python or C#, with demonstrated experience designing and building QA automation frameworks from the ground up.
• Strong preference for Unity and Unity tooling, with hands-on experience testing game systems and client-side behavior; experience with other game engines also considered
• Demonstrated fluency with coding agents as a daily engineering tool — not just prompting, but integrating AI into test creation, debugging, and code review with sound judgment about when to steer, verify, and override
• Ability to think abstractly about test coverage: you define the problem space before reaching for solutions, and build systems that adapt to changing content rather than hard-coded approaches
• Experience with complex, interconnected game systems — combat, progression, economy, or procedural content — and validating correctness across large combinatorial spaces
• Experience with CI/CD platforms such as GitHub Actions, Jenkins, or TeamCity, and the ability to integrate automated content tests into build pipelines.
• Demonstrated ability to collaborate cross-functionally, balance shifting priorities, and deliver iteratively in a fast-moving prototyping environment.
• Nice to have: Knowledge of AWS cloud services and experience with load testing infrastructure or distributed test execution.

• Elevate performance and visual quality through advanced optimization techniques for mobile platforms (e.g., draw calls, shaders, polycounts, overdraw).
  
  
• Champion collaboration and knowledge sharing by modeling best practices and influencing cross-functional initiatives at the organizational level.

What You’ll Need to be Successful

• Extensive experience as a Technical Artist in game development, with expertise across Unity and DCC tools (Blender, Substance, Maya, Photoshop).
  
  
• Proven track record of building and scaling cross-functional pipelines that serve multiple projects.
  
  
• Strong programming/scripting skills in C# and Python, with deep experience developing automation and pipeline tools.
  
  
• Mastery of mobile performance optimization and rendering pipelines (URP).
  
  
• Hands-on experience with cutting-edge workflows (e.g., procedural generation, AI-assisted art, real-time rendering).
  
  
• Demonstrated success in mentoring and guiding Sr. ICs, aligning their work to broader business and creative goals.
  
  
• Excellent collaboration and communication skills, with the ability to influence senior leadership and drive cross-functional alignment.
  
  
• Comfort navigating ambiguity, making strategic decisions with limited precedent while ensuring execution remains on track
