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're looking for experienced, passionate, and resourceful staff-level engineers to join our Identity backend team. You'll help build the systems that provide effortless, secure access across EarnIn's expanding consumer and enterprise ecosystem, ensuring legitimate users can move forward seamlessly while stopping bad actors in their tracks. As a staff engineer, you'll work cross-functionally to ship resilient identity infrastructure at scale, harnessing agentic workflows and modern AI tooling to multiply your impact.
This is a remote position, though it could also be a hybrid role from our Mexico City office as part of our expanding site. EarnIn offers excellent benefits for our employees, including healthcare, internet and cell phone reimbursement, a learning and development stipend, and potential opportunities to travel to our Mountain View headquarters. Our salary ranges are determined by role, level, and location. We are unable to provide visa sponsorship or immigration support for this position.    

WHAT YOU'LL DO
  • System Design and Architecture: Design, architect, and implement identity management solutions that meet the organization's security and scalability requirements.
  • Identity Integration: Seamlessly integrate identity services into our applications to ensure a cohesive user experience across multiple platforms.
  • Own delivery from design through launch, partnering across teams to ship safely and maintain platform stability.
  • Stay abreast of emerging technologies and industry trends in identity management, and proactively identify opportunities for process improvements and optimization.
  • Create and maintain test automation to enable continuous integration and development velocity.
  • Design & deliver thoughtfully crafted REST APIs to drive the interactions between our client applications and backend services.
  • Collaborate and mentor other engineers while providing thoughtful guidance using code, design, and architecture reviews.
  • Work cross-functionally with other teams (data science, design, product, marketing, analytics).
  • Leverage a broad skill set and help us implement and learn new technologies quickly.
  • Provide and receive design and implementation evaluations and improve with each iteration.
  • Debug production issues across our services infrastructure and multiple levels of our stack.
WHAT WE'RE LOOKING FOR 
  • 7+ years of development experience in a fast-paced environment.
  • Bachelor's, Master’s, or PhD degree in computer science, computer engineering, or a related technical discipline, or equivalent industry experience.
  • Hands-on experience building agentic workflows and multi-agent systems, orchestrating with guardrails to automate real engineering work end-to-end.
  • Adept in at least one modern programming language such as C#, Java, or JavaScript.
  • Deep knowledge of various databases (DynamoDB, MySQL), stream processing technologies (Kafka), and event-driven architecture patterns.
  • Production experience operating Kubernetes and designing resilient microservice architectures at scale.
  • Experience using AI-assisted development tools (e.g., GitHub Copilot, Cursor, ChatGPT, or similar tools) as part of your software development workflow
  • Proficiency in an identity management system, such as Okta, Auth0, Keycloak, or similar.
  • Strong understanding of authentication protocols and standards (e.g., OAuth 2.0, OpenID Connect, SAML), familiarity with RBAC/ABAC, MFA, and other  identity and access management (IAM) concepts
  • Advanced English proficiency (written and spoken)

What We Do

Earnin’s mission is to build a financial system that works for people. Every year, while Americans wait for their paychecks, more than $1 trillion of their hard-earned money is held up in the pay cycle. As a result, we accumulate over $50 billion in late and overdraft fees and turn to high-interest loans. We seek to eliminate those fees and put money back into workers’ hands. Our financial system doesn’t work for people. But Earnin does. Earnin is an app that lets people get paid as soon as they leave work, with no fees, interest, or hidden costs. App users can receive their money in their bank account instantly at little or no cost — as we operate on a pay what you choose model. All they need is a bank account and a job that provides direct deposit or uses electronic timesheets. At Earnin, we’re building the way we think a financial system should work for everyone, not just the people who can afford it. We help people take control of their money and get to a better financial place. Our goal is not only to provide great products at little or no cost to the people who need them but also to inspire kindness across the financial world and eventually across all industries.
