Senior DevOps Engineer (Contract / Remote)

About EnrollWise EnrollWise is a leading enrollment management platform trusted by major U.S. school districts. We deliver robust, secure, and scalable solutions built on a modern tech stack, including Python/Django with Graphene for GraphQL APIs, Next.js (React + TypeScript), PostgreSQL, Redis, Celery for task queuing, and cloud-based infrastructure with dynamic horizontal scaling using AWS services like ECS, Fargate, S3, and CloudWatch. We're committed to innovation in education technology, powering seamless integrations with third-party services like Twilio, SmartyStreets, Census, ArcGIS, and Student Information Systems. Role Overview We're seeking an experienced Senior DevOps Engineer to audit our current infrastructure and Python/Django application, provide expert recommendations, and guide the transition to a shared tenant (multi-tenant) architecture. Our existing DevOps team handles day-to-day operations, but we need your specialized expertise in high-availability, high-traffic systems to optimize for peak enrollment cycles and ensure enterprise-grade performance as we scale. This position is a contract role and can work remotely anywhere in the US. Collaboration with our team during US business hours is required. Key Responsibilities - Conduct a comprehensive audit of our AWS-based infrastructure (including ECS, Fargate, Terraform IaC, CloudWatch/Sentry monitoring, and disaster recovery setups) and Python/Django application to identify scalability, performance, reliability, and security gaps. - Recommend and implement best practices for high-availability architectures, fault-tolerant mechanisms, and elastic scaling to handle high-traffic scenarios without downtime. - Design and set up a shared tenant instance model, ensuring data isolation, independent scaling per tenant, and compliance with security standards. - Facilitate load testing processes to identify performance optimization opportunities. - Collaborate with our engineering team to enhance CI/CD pipelines, automate deployments, and integrate observability tools for proactive monitoring and alerting. Qualifications - 7+ years of DevOps experience, with proven expertise in building and optimizing high-availability, high-traffic applications (e.g., handling peak loads in SaaS environments). - Deep knowledge of AWS services (ECS, Fargate, S3, CloudFront, WAF, CloudWatch) and Infrastructure-as-Code tools like Terraform. - Familiarity with Python/Django ecosystems, including GraphQL (Graphene), task queues (Celery), and databases (PostgreSQL, Redis). - Experience designing multi-tenant architectures with emphasis on isolation, scalability, and security. - Expert knowledge of containerization (Docker), monitoring/anomaly detection. - Excellent problem-solving skills and ability to communicate technical recommendations clearly. - Prior consulting or auditing roles in fast-growing startups or enterprise environments. Why Join Us? - Make a meaningful impact on education by enhancing a platform that serves millions of students and families. - Flexible part-time schedule. Fully remote. - Competitive hourly rate commensurate with experience.
