Senior DevOps Engineer (Contract / Remote)
关于EnrollWise
EnrollWise是一个被美国主要学区信赖的招生管理平台。我们提供强大、安全且可扩展的解决方案，基于现代技术栈构建，包括Python/Django配合Graphene用于GraphQL API，Next.js（React + TypeScript），PostgreSQL，Redis，Celery用于任务队列，以及使用AWS服务如ECS、Fargate、S3和CloudWatch的云基础设施，支持动态横向扩展。
我们致力于教育科技领域的创新，为第三方服务如Twilio、SmartyStreets、Census、ArcGIS和学生信息系统提供无缝集成。
职位概述
我们正在寻找一位经验丰富的高级DevOps工程师，对我们的现有基础设施和Python/Django应用进行审计，提供专业建议，并指导过渡到共享租户（多租户）架构。我们现有的DevOps团队负责日常运营，但我们需要您在高可用性、高流量系统方面的专业知识，以优化高峰招生周期的表现，并确保我们在扩展过程中具备企业级性能。
该职位是合同制，可以在美国任何地方远程工作。需要与我们的团队在美国内业务时间进行协作。
主要职责
- 对基于AWS的基础设施（包括ECS、Fargate、Terraform IaC、CloudWatch/Sentry监控和灾难恢复设置）及Python/Django应用进行全面审计，识别可扩展性、性能、可靠性和安全性方面的差距。
- 推荐并实施高可用性架构的最佳实践，故障容错机制和弹性扩展，以在无停机情况下处理高流量场景。
- 设计并建立共享租户实例模型，确保数据隔离、每个租户独立扩展，并符合安全标准。
- 协助负载测试流程，识别性能优化机会。
- 与我们的工程团队合作，提升CI/CD流水线，自动化部署，并集成可观测性工具以实现主动监控和警报。
任职要求
- 7年以上DevOps经验，有构建和优化高可用、高流量应用的实战经验（例如处理SaaS环境中的峰值负载）。
- 精通AWS服务（ECS、Fargate、S3、CloudFront、WAF、CloudWatch）和基础设施即代码工具如Terraform。
- 熟悉Python/Django生态系统，包括Graphene等工具。

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.
