About Evallo

Evallo is redefining education management through a comprehensive SaaS platform designed for tutors and tutoring businesses. Our solution streamlines essential operations--from advanced CRM and profile management to standardized test prep, automatic grading, and real-time dashboards. By enabling educators to focus on what they do best--teaching--we're pushing the boundaries of ed-tech and delivering the future of efficient, scalable learning systems.

Why This Role Matters

Evallo is evolving from a specialized tutoring platform into a modular operating system for all service businesses that bill by the hour. As we expand our product offering to include integrated payroll, proposals, whiteboarding, and AI-powered tools, we are seeking a Tech Lead with strong architectural expertise in AWS and platform design.

You will be instrumental in translating high-level product vision into a scalable, maintainable technical foundation. Your leadership will ensure we remain stable with 5,000+ concurrent users and cost-efficient at 100,000+ total users--all while enabling rapid product evolution.

Key ResponsibilitiesSolution Architecture & Technical Design

Analyze and document the current platform architecture; identify bottlenecks and produce a formal Architecture Gap Report. Translate product epics into modular service contracts, data flow diagrams, and scalable system components. Decide and implement optimal architectural patterns (monolith vs. microservices, REST vs. event-driven, DB index vs. cache). Drive scalable multi-tenant architecture for user/workspace models and complex permission systems.

Platform Standards & DevOps

Define and enforce platform-wide standards, including naming conventions, code formatting rules, ADRs, and review checklists. Collaborate with DevOps to design high-availability infrastructure and auto-scaling environments on AWS (EC2, S3, IAM, CloudFront, Cognito). Own CI/CD pipelines and schema migration strategies with an emphasis on zero-downtime deployments and one-click rollbacks. Monitor infrastructure spend and optimize for performance and cost; guide usage of serverless functions, queues, and caching layers.

Observability & Performance

Lead the implementation of observability practices using Datadog, New Relic, Sentry, or OpenTelemetry. Ensure platform metrics are monitored with < 10% infrastructure cost waste and < 5 false positive alerts per month. Design and execute load-testing scenarios replicating high-concurrency use cases.

Team Mentorship & Leadership

Mentor junior and mid-level engineers through code reviews, architecture clinics, and pair programming sessions. Facilitate cross-team architecture reviews and ensure no major feature ships without architectural alignment. Balance hands-on development (80%) with leadership duties (20%)--reviewing designs, resolving technical debates, and maintaining engineering discipline.

Requirements

5+ years of software engineering experience, including 2+ years in an architecture or senior technical leadership role. Strong full-stack expertise with MERN stack (MongoDB, Express.js, React.js, Node.js). Demonstrated success in designing multi-tenant architectures and scalable systems handling 1,000+ requests per minute. Advanced proficiency in AWS, including EC2, Lambda, RDS, IAM, CloudFront, and Cognito. Familiarity with CI/CD tools (GitHub Actions, Jenkins, Bitbucket Pipelines). Experience working with observability stacks like Datadog, New Relic, or OpenTelemetry. Excellent written and verbal communication skills; capable of summarizing trade-offs clearly for both technical and non-technical stakeholders.

Preferred Qualifications

Prior experience with education platforms or SaaS tools for service businesses. Experience with event brokers such as Kafka, NATS, or RabbitMQ. Deep knowledge of schema design, role-based access control, and data migration in NoSQL environments.

What We're Looking For

A leader with a builder's mindset--you thrive in early-stage environments and care deeply about long-term scalability. Someone who brings both hands-on technical depth and a strategic architectural perspective. An engineer who leads with clarity, communicates trade-offs effectively, and takes full ownership of outcomes.
