POSITION SUMMARY
EarnIn is seeking a Senior Frameworks Engineer to design, build, and evolve the shared frameworks and libraries that power our microservices and APIs across multiple runtimes, with a primary focus on Golang and secondary support for Kotlin/Spring Boot. As part of the Developer Experience team, you will be a domain expert who strengthens the foundational plumbing of our services—including bootstrappers, observability, authentication, communication protocols, and CI/CD scaffolding. You will deliver impactful solutions that simplify complexity for developers, enabling them to build high-quality, scalable systems more efficiently.
In this role, you’ll collaborate closely with teammates and cross-functional partners, contribute to technical strategy through thoughtful design and implementation, and advocate for frameworks that improve both developer experience and customer outcomes. You will balance short-term deliverables with long-term maintainability, mentor junior engineers, and model mission-driven ownership, creativity, and resilience.
This position will ideally be a hybrid role based in our Bangkok office, as part of our expanding site locations. EarnIn provides excellent employee benefits, including healthcare, internet/cell phone reimbursement, a learning and development stipend, and potential opportunities to travel to our Palo Alto HQ. Our salary ranges are determined by role, level, and location.

WHAT YOU'LL DO
- Design, implement, and maintain core frameworks and libraries in Golang that support bootstrapping, shared services, observability hooks, authentication, RPC/REST tooling, and CI/CD templates.
- Partner with the Kotlin framework owner and other engineers to ensure cross-runtime consistency, enabling a unified developer experience across Go, Kotlin, and other supported runtimes.
- Build reusable components for logging, tracing, metrics, configuration management, rate limiting, and service-to-service communication.
- Keep shared frameworks aligned with evolving industry standards (e.g., OpenTelemetry, gRPC/HTTP middleware, Go upgrades, Spring Boot integrations), reducing fragmentation and technical debt.
- Participate in architecture and design reviews, providing well-thought-out recommendations and advocating for best practices.
- Deliver solutions that balance speed, quality, and scalability, ensuring testing, monitoring, and performance considerations are built into your work.
- Contribute to code reviews and support teammates through documentation, guidance, and collaborative problem-solving.

- Demonstrate ownership by anticipating near-term challenges, proactively mitigating risks, and following through on commitments with transparency and integrity.
WHAT WE'RE LOOKING FOR
- Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related field (or equivalent practical experience).
- 4+ years of software development experience, including contributions in framework, platform, or infrastructure engineering.
- Strong expertise in Golang and experience building frameworks, libraries, or developer tooling.
- Experience with Kotlin/Java (Spring Boot) or other backend runtimes (C#, Python, TypeScript) is a plus.
- Knowledge of service-oriented and event-driven architectures, including gRPC, REST, and messaging/eventing systems.
- Familiarity with observability stacks, OpenTelemetry, and performance tuning.
- Experience with AWS managed services, container orchestration (Kubernetes), and CI/CD pipelines.
- Strong communication skills with the ability to advocate for customers, collaborate effectively with teammates, and approach challenges with candor and compassion.

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.
