About EarnIn

As one of the first pioneers of earned wage access, our passion at EarnIn is building products that deliver real-time financial flexibility for those with the unique needs of living paycheck to paycheck. Our community members access their earnings as they earn them, with options to spend, save, and grow their money without mandatory fees, interest rates, or credit checks.

We’re fortunate to have an incredibly experienced leadership team, combined with world-class funding partners like A16Z, Matrix Partners, DST, Ribbit Capital, and a very healthy core business with a tremendous runway. We’re growing fast and are excited to continue bringing world-class talent onboard to help shape the next chapter of our growth journey.

POSITION SUMMARY
 
We are looking for an experienced, passionate, and resourceful Software Development Engineer (SDE) to join our team and own testability as a first-class engineering discipline. This is not a QA role — you are a builder. You will design, build, and maintain the services, tools, and RESTful APIs that make our fintech systems inherently testable, observable, and safe to change quickly. You’ll partner closely with engineering teams across the org to embed testability and quality practices directly into how services are architected and shipped — not bolt them on after the fact. You’ll have the chance to work on interesting fintech problems and make a real difference in the lives of our customers by making our engineering org faster and safer to ship in.
 
This position is ideally hybrid, based in our Palo Alto office. We’re also open to candidates who can relocate or who are located in the PT or CT time zones. Our salary ranges are determined by role, level, and location. The US base salary range for this position is $152,000 – $185,800.  Note: This role is intentionally scoped as a Software Development Engineer role, not a Quality Assurance role. The ideal candidate identifies as a builder of platforms and services first, who happens to specialize in testability — not a QA engineer who writes automation.

WHAT YOU’LL DO
  • Design, build, and maintain backend services and RESTful APIs that expose testability as a platform capability (e.g., test hooks, state seeding/reset, fault injection, synthetic data generation, environment control)
  • Architect and implement “backdoor” testing interfaces and controlled test-only entry points that allow engineering and automation teams to safely manipulate system state, simulate edge cases, and validate behavior without compromising production integrity or security
  • Evangelize testability and quality engineering practices across cross-functional teams (product, backend, mobile, data science, design) — influencing how services are designed from day one to be observable, controllable, and verifiable
  • Partner with development teams to understand product and system architecture, identifying testability gaps in microservices (REST and gRPC) and proposing platform-level solutions
  • Build and own internal tooling, SDKs, and libraries that make it easy for any engineering team to adopt testability best practices with minimal friction
  • Define and track quality and testability metrics/SLAs across services; drive adoption through data, not mandate
  • Collaborate with and mentor engineers across teams, providing technical guidance on test architecture, service design, and quality engineering patterns
  • Work closely with security and platform teams to ensure testability features (backdoors, hooks, overrides) are safely scoped, access-controlled, and cannot be exploited in production
  • Champion AI-native/AI-first approaches to testability and quality — using AI/LLM-based tooling to auto-generate test cases, synthetic data, and edge-case scenarios, and to accelerate root-cause analysis of failures
  • Build and integrate AI-powered agents into the testability platform (e.g., agents that can autonomously exercise APIs, detect regressions, or generate test coverage reports) to scale quality engineering beyond manual effort
  • Evaluate and pilot emerging AI coding/testing tools, establishing patterns for how engineering teams org-wide should adopt AI-assisted development and testing responsibly
WHAT WE’RE LOOKING FOR
  • 7+ years of software engineering experience building production backend services, with a strong track record of writing high-quality, well-tested, maintainable code
  • Bachelor’s or Master’s degree in Computer Science, Computer Engineering, or a related technical discipline, or equivalent industry experience
  • Demonstrated experience designing and building testability infrastructure, internal developer tools, or platform services consumed by other engineering teams
  • Strong hands-on experience building and maintaining RESTful APIs and services in a microservices architecture (REST and gRPC)
  • Proven ability to design safe, access-controlled “test-only” interfaces or hooks into production-adjacent systems without introducing security or reliability risk
  • Solid understanding of software quality methodologies and how to translate them into platform capabilities rather than manual processes
  • Experience with CI/CD tooling and integrating testability/quality tooling into build and deployment pipelines
  • Excellent written and verbal communication skills, with experience influencing and evangelizing engineering practices across teams without direct authority
  • Experience with Kubernetes and microservice architecture is a strong plus
  • Genuine enthusiasm for AI-native/AI-first engineering — hands-on experience using LLMs/AI agents to generate tests, synthetic data, or automate quality workflows, and a point of view on where AI should (and shouldn’t) be trusted in a testability platform
  • Experience using AI-assisted development tools (e.g., GitHub Copilot, Cursor, ChatGPT, or similar tools) as part of your software development workflow?

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
