About the role
We are looking for a Senior Staff Software Engineer to drive the overarching strategy, technical vision, and execution across Nu’s Quality & Developer Experience ecosystem. You will sit at the epicenter of our engineering transformation.
This role goes far beyond traditional quality assurance or testing; you will own the end-to-end (E2E) Developer Experience (DevEx) across the entire Software Development Life Cycle (SDLC). From internal developer platform tools and boundary APIs to our suite of testing mechanisms and automated code reviews, your mission will be to architect AI-native systems that drastically reduce review latency, guarantee architectural correctness, and double engineering productivity across Nu. Working alongside our most tenured engineering leaders and reporting into platform leadership, you will serve as the technical authority who brings fresh, market-leading perspectives from high-velocity environments to elevate our foundational standards.
Mission
Architect, scale, and operationalize an AI-transformed Developer Experience & Quality strategy so that:
The "Secure and Quality Path" is the Default: Automated mechanisms, linting, and smart context-aware agents enforce strict architectural standards, eliminating code quality degradation caused by high-volume AI code generation.
Developer Velocity Doubles (2x): The friction in review latency, pull request (PR) approvals, and continuous integration is systematically dismantled, enabling thousands of engineers to ship features safely to 140M+ customers at unprecedented speeds.
SDLC is Re-imagined for AI: Foundational tools across code authorship, testing, boundary APIs, and PR reviews are seamlessly integrated with state-of-the-art AI frameworks, smart LLM evaluations, and context-engineering hooks.
Automated Approval Standards are Built: Clear deterministic checks and intelligent human-in-the-loop triggers are established to achieve safe, automated PR approvals without manual bottlenecks.
Core Responsibilities
Architect E2E Quality & DevEx Platforms: Define and evolve the multi-year vision for our developer tooling ecosystem—covering internal developer platforms, boundary APIs, test automation suites, and pull request review systems.
Lead the AI-Driven Code Review Evolution: Architect automated review mechanisms that leverage multi-model evaluations (e.g., using specialized LLMs to audit generated code), custom IDE/GitHub plugins, and deterministic linting to accelerate PR merge times while preventing code bloat or quality degradation.
Define Human-in-the-Loop Boundaries: Set company-wide paradigms for when code changes can be automatically approved and merged versus when human intervention or secondary AI audits are required.
Partner & Mentor Across Engineering: Act as a force multiplier by partnering with engineers and product managers, elevating the technical bar and instilling modern, high-velocity DevEx practices.
Balance AI Speed with System Integrity: Establish observability, defect-tracking metrics, and safety rails to ensure that rapid AI-assisted development does not introduce structural fragility into Nu's core services.
Influence Build vs. Buy Strategy: Evaluate top-tier market tools, AI coding frameworks, and internal platforms to decide when to build bespoke internal agents or integrate emerging third-party tooling.
Key Business & Engineering Metrics You Will Influence
Developer Productivity & Velocity
Achieve a 2x improvement in overall engineering productivity across Nu's engineering organization.
PR Review Latency
Direct reduction in time-to-merge for pull requests across all BUs and countries.
Code Base Health & Quality
Zero degradation in code quality and zero increase in system defects despite exponentially higher volumes of AI-generated code.
Automated PR Approvals
Increase in the percentage of routine, low-risk code changes safely approved and merged via automated mechanisms.
Platform Adoption & Satisfaction
High adoption and developer satisfaction (CSAT) across proprietary internal DevEx tools and boundary APIs
Challenges and Opportunities (What You’ll Own)
Navigating Scale: Every change you introduce to the SDLC impacts thousands of microservices and hundreds of engineering teams delivering features to over 140 million users.
Tackling "Code Slop" at the Root: As AI agents generate code faster than humans can read it, you will solve one of the industry's newest and hardest problems: keeping codebase quality high without slowing down the team.
High Autonomy & Strategic Breadth: You will operate with autonomy, driving horizontal technical alignment without needing micro-oversight, helping lead our joint DevEx technical council.
Core Qualifications (What We're Looking For)
Senior IC Leadership Track Record: backend software engineering experience, with a proven track record designing developer platforms, core infra, or DevEx systems at high scale.
Deep DevEx & SDLC Expertise: Extensive domain depth in code review systems, test automation platforms, CI/CD pipelines, developer platforms, or static analysis tools built for massive engineering organizations.
AI Transformation & Tooling Experience: Direct hands-on experience or deep technical familiarity with AI-assisted software development—including LLM evaluation pipelines, GitHub Copilot/agent integrations, prompt/context/graph engineering, or AI-driven code review frameworks.
Autonomous & Opinionated Technical Leader: Demonstrable history of driving technical strategy independently, navigating ambiguity, and bringing strong, battle-tested opinions on "what good looks like" in modern software development.
High-Velocity Culture Fit: Experience operating in fast-moving, high-bar environments (e.g., top-tier tech firms, high-growth AI/DevEx startups, or elite AI labs) where speed of execution and technical rigor are equally valued.

Know your rights as a candidate and an employee:
The job is in Palo Alto, CA. Below is what the official statistics say about living and working there.
How Palo Alto compares. Among the 145 largest places in California, Palo Alto is #122 by population, #4 for college degrees (#1 = most), #139 for rent (#1 = cheapest), #7 for household income (#1 = highest). Its county, Santa Clara County, is #1 of 58 counties for average pay ($197,043).
Palo Alto has 67,237 residents (ACS 2020–2024), about 0.2% of the population of California. It covers 24 square miles of land, which works out to roughly 2,796 people per square mile. The median age is 43.6, 15% older than the state median (43.6 against 37.9).
The median gross rent is $3,484 a month (rent plus utilities), 71% above the state median ($3,484 against $2,036). Over a year that is 18.1% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is above $2 million (the ACS reports $2,000,001 as its highest value, so the true median is higher), which is at least 8.7 times the median household income ($231,101); a ratio above 5 usually means buying is out of reach without savings or a second income. 54.6% of households own their home, about the same as the state average (54.6% against 55.9%).
The San Jose-Sunnyvale-Santa Clara, CA metropolitan area has 1,134,970 jobs in the BLS wage survey, and the median pay across all occupations is $84,050 a year, 65% above the national median ($84,050 against $50,980). The biggest occupation groups are computer and mathematical (149,970 jobs, median $186,320); management (115,110 jobs, median $210,750); business and financial operations (94,210 jobs, median $125,240). The area is most specialised in computer and mathematical (3.9 times) and architecture and engineering (2.5 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are management ($210,750) and legal ($195,190). In 2026M09 the unemployment rate of Santa Clara County was 4.2%. 62.3% of residents aged 16 and over are in the labour force. The city lies in Santa Clara County; its jobs, pay by industry and GDP are on the county page.
Among workers, 44.2% drive alone, 2.0% use public transit, 4.6% walk, 35.4% work from home. 8.2% of workers commute 45 minutes or more, 58% below the state average (8.2% against 19.4%). Remote work is more common than in the state as a whole, which widens the set of employers a resident can work for without moving.
82.3% of adults aged 25 and over hold a bachelor's degree or higher, 122% above the state share (82.3% against 37.1%). 37.0% of residents were born outside the United States, 37% above the state share (37.0% against 27.0%). The poverty rate is 6.0%, 50% below the state rate (6.0% against 12.0%).
The warmest month is Aug, averaging 68°F (19.8°C), and the coolest is Jan at 47°F (8.3°C). About 510 mm (20 inches) of precipitation falls in a year; Dec is the wettest month (114 mm) and Jul the driest (0 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.
