POSITION SUMMARY Join EarnIn's Enterprise IT team in Bengaluru to design and own integrations across our core business systems: Finance, HR, Legal, and Compliance, as we build the technology infrastructure for public company readiness. This position will be a hybrid role based in our Bengaluru office, with 2 days on-site as part of our expanding site. EarnIn provides excellent benefits for our employees, including healthcare, internet/cell phone reimbursement, a learning and development stipend, and potential opportunities to travel to our Mountain View HQ. Our salary ranges are determined by role, level, and location. WHAT YOU'LL DO Design, build, and maintain integrations across EarnIn's enterprise application stack, including NetSuite (ERP), ADP (payroll), Workday (HRIS), Carta (equity management), Greenhouse (recruiting), Okta (identity), Pigment (FP&A), and Zip (procurement) using direct REST/SOAP API integrations. Lead end-to-end integration delivery: requirements gathering with business partners in Finance, HR, Legal, and Compliance; solution design; development; testing; and production deployment, operating with a high degree of autonomy and ownership. Automate manual data exchange workflows currently operating through spreadsheets, reducing operational risk and improving data fidelity across systems of record. Partner with the Analytics Engineering team on data exchange contracts for EarnIn's financial reconciliation platform, where integration touchpoints are required. Build and maintain custom applications and workflow extensions within enterprise platforms (e.g., NetSuite SuiteScript, Workday Studio, Okta Workflows) where native integrations do not meet EarnIn's business requirements. Implement and maintain SOX ITGC-compliant controls across managed systems, including change management, audit logging, access provisioning, and segregation-of-duties workflows, to support EarnIn's IPO readiness program. Partner with the Enterprise IT Applications Manager and US-based team to evolve the integration architecture roadmap, contribute to technology selection decisions, and ensure integrations scale with EarnIn's business growth. WHAT WE'RE LOOKING FOR Bachelor's, Master’s, or PhD degree in computer science, computer engineering, or a related technical discipline, or equivalent industry experience. 4+ years of hands-on experience designing and operating enterprise application integrations in SaaS environments, with demonstrated ownership across the full integration lifecycle from design to production support. Proficiency with at least one iPaaS or middleware platform and solid command of RESTful and SOAP API patterns, OAuth 2.0, SCIM provisioning, and webhook-driven architectures. Significant hands-on experience building with AI, including coding with AI-assisted tools (Claude Code, GitHub Copilot, Cursor, or equivalent) as a primary development workflow, integrating LLM APIs into business applications, and designing and deploying multi-step AI agents using frameworks such as LangChain, LangGraph, or the Anthropic Agent SDK. Hands-on experience with ERP systems (NetSuite preferred) and HRIS platforms (Workday preferred), plus proficiency in programming in Python or JavaScript/Node.js for custom data transformation and automation work. Moderate experience with SOX ITGC requirements (change management controls, audit log management, segregation of duties documentation) and identity and access provisioning via Okta or equivalent (SAML 2.0, SCIM, RBAC). Some experience mentoring engineers, leading technical design reviews, and translating ambiguous business requirements into integration and automation architectures in a cross-functional environment. Experience using AI-assisted development tools (e.g., GitHub Copilot, Cursor, ChatGPT, or similar tools) as part of your software development workflow #LI-Hybrid At EarnIn, we believe that the best way to build a financial system that works for everyday people is by hiring a team that represents our diverse community.
