POSITION SUMMARY EarnIn is scaling the systems, automations, and data capabilities that power our people and protect our information. As a Senior Systems Integration Engineer (IC4), you’ll be a hands-on technical lead focused on Python-driven automation, building systems integrations between HRIS, Identity Provider, SaaS, and Finance Platform, and transforming operational data into actionable insights and dashboards. You’ll own high-impact projects end-to-end, mentor teammates, and raise the bar on reliability, security, and employee experience. This position will be hybrid from our Mexico City office and requires at least two days a week in the office, though a remote arrangement may be possible.

Our salary ranges are determined by role, level, and location. WHAT YOU'LL DO Python Automation and Internal Tooling Design, build, and maintain production-grade automations and internal tools in Python to eliminate manual work across identity, endpoint, and SaaS operations (e.g., joiner–mover–leaver, provisioning, deployment, remediation). Develop resilient API integrations and event-driven workflows (webhooks, queues) with robust error handling, retries, and observability; package reusable libraries and CLIs that standardize how IT automates. Codify repeatable infrastructure with Terraform; manage changes via Git and CI/CD (e.g., GitHub Actions).

Build data warehouses (e.g., Databricks) and write SQL against them (e.g., BigQuery) and build self-serve dashboards for IT, Security, Finance, People Ops, and Engineering; instrument pipelines for accuracy and freshness. Deliver repeatable, audit-ready evidence for controls via dashboards and scheduled reports. AI Enablement Evaluate and deploy AI tools with guardrails to boost IT productivity; automate helpdesk workflows (triage, summarization, routing, knowledge search). Define and track value metrics (adoption, deflection, CSAT, MTTR, time saved); iterate based on experiments and user feedback. Reliability, Security and Compliance Implement and sustain controls mapped to SOC 2 and PCI (as applicable) with repeatable evidence collection. Define and review SLIs/SLOs; add monitoring/alerting, config drift detection, and incident runbooks.
