Solutions Architect

Company Description

Evallo is a leading provider of a comprehensive SaaS platform for tutors and tutoring businesses, revolutionizing education management. With features like advanced CRM, profile management, standardized test prep, automatic grading, and insightful dashboards, we empower educators to focus on teaching. We're dedicated to pushing the boundaries of ed-tech and redefining efficient education management.

Why this role matters

Evallo is scaling from a focused tutoring platform to a modular operating system for all service businesses that bill by the hour. As we add payroll, proposals, white-boarding, and AI tooling, we need a Solution Architect who can translate product vision into a robust, extensible technical blueprint. You’ll be the critical bridge between product, engineering, and customers—owning architecture decisions that keep us reliable at 5k+ concurrent users and cost-efficient at 100k+ total users.

Outcomes we expect

• Map current backend + frontend, flag structural debt, and publish an

  Architecture Gap Report

• Define naming & layering conventions, linter / formatter rules, and a lightweight ADR process
• Ship reference architecture for new modules
• Lead cross-team design reviews; no major feature ships without architecture sign-off

Eventual goal is to have Evallo run in a fully observable, autoscaling environments with < 10 % infra cost waste. Monitoring dashboards should trigger < 5 false positives per month.

Day-to-day

• Solution Design: Break down product epics into service contracts, data flows, and sequence diagrams. Choose the right patterns—monolith vs. microservice, event vs. REST, cache vs. DB index—based on cost, team maturity, and scale targets.
• Platform-wide Standards: Codify review checklists (security, performance, observability) and enforce via GitHub templates and CI gates. Champion a shift-left testing mindset; critical paths reach 80 % automated coverage before QA touches them.
• Scalability & Cost Optimization: Design load-testing scenarios that mimic 5 k concurrent tutoring sessions; guide DevOps on autoscaling policies and CDN strategy. Audit infra spend monthly; recommend serverless, queuing, or data-tier changes to cut waste.
• Release & Environment Strategy: Maintain clear promotion paths: local → sandbox → staging → prod with one-click rollback. Own schema-migration playbooks; zero-downtime releases are the default, not the exception.
• Technical Mentorship: Run fortnightly architecture clinics; level-up engineers on domain-driven design and performance profiling. Act as tie-breaker on competing technical proposals, keeping debates respectful and evidence-based.

Qualifications

• 5+ yrs engineering experience, 2+ yrs in a dedicated architecture or staff-level role on a high-traffic SaaS product.
• Proven track record designing multi-tenant systems that scaled beyond 50 k users or 1k RPM.
• Deep knowledge of Node.js / TypeScript (our core stack), MongoDB or similar NoSQL, plus comfort with event brokers (Kafka, NATS, or RabbitMQ).
• Fluency in AWS (preferred) or GCP primitives—EKS, Lambda, RDS, CloudFront, IAM.
• Hands-on with observability stacks (Datadog, New Relic, Sentry, or OpenTelemetry). 
• Excellent written communication; you can distill technical trade-offs in one page for execs and in one diagram for engineers.
