## Role Summary

We are seeking a Staff Software Engineer to join one of the engineering teams building KnowBe4's core Security Awareness Training product. This is a full-stack role requiring depth across a Ruby on Rails backend, modern front-end technologies (Vue 3, SvelteKit), and complex AWS infrastructure.

As a Staff Engineer, you are a technical leader in day-to-day engineering. You drive direction through architectural ownership of the systems your team builds, high-impact code contributions, and cross-team influence.

You'll work within a platform ecosystem of microservices deployed across our AWS regions, helping ensure we meet rigorous FedRAMP Moderate, SOC 2, and ISO 27001 standards. Our front-end is actively evolving — we're rewriting our micro-frontends (MFEs) to Vue 3 — so you'll both shape that migration and keep our current SvelteKit application healthy. You lead through your engineering, your judgment, and your ability to bring other engineers along with you.

## What You'll Build

- Full-stack product features and subsystems: Ruby on Rails APIs, GraphQL endpoints, and Vue 3 / SvelteKit + TypeScript front-ends that ship real value to a global customer base
- The Vue 3 front-end direction: owning key parts of the micro-frontend (MFE) rewrite onto Vue 3, setting patterns others build on, while keeping the existing SvelteKit application maintainable
- GraphQL APIs at scale: schema design, batch loading, and query complexity management for high-traffic, multi-tenant access patterns
- Event-driven services: EventBridge/SQS-based communication between microservices, with an emphasis on idempotency, reliability, and asynchronous processing at scale
- Serverless background processing: evolving and optimizing our Lambda-backed worker framework (400+ workers) that powers the product's async workload
- Multi-tenant data strategy: architecting patterns across MySQL, PostgreSQL, DynamoDB, and Redis while maintaining strict tenant isolation and compliance guarantees
- Infrastructure-as-Code: Terraform modules and GitLab CI/CD pipelines that provision and deploy services across multiple environments and regions
- Technical direction: architecture reviews, Architecture Decision Records (ADRs), and cross-team coordination on changes that reach beyond a single service

Essential Responsibilities

- Develops software using the KnowBe4 Software Development Lifecycle and Agile methodologies
- Assists other team members by providing technical direction
- Defines approaches and solutions to complex technical problems
- Owns the evolution of major subsystems within the team's domain
- Translates KnowBe4's strategic goals into technical roadmaps in collaboration with Product, Security, and Infrastructure teams
- Sets the bar for code quality and engineering patterns through rigorous reviews and technical guidance for senior engineers
- May act as technical lead for larger sub-projects or entire small projects

## Skills Requirements

- Backend & Systems — 5+ years scaling production Ruby on Rails applications; expertise in GraphQL (batch loading, complexity management) and relational databases tuning (MySQL/PostgreSQL) for high-traffic, multi-tenant systems
- Frontend — Strong proficiency with a modern component framework and strict TypeScript; Vue 3 experience is preferred given our MFE direction, and SvelteKit experience is highly valued for our current codebase (React also translates well); proven ability to lead large-scale front-end work using Vite and Tailwind CSS
- Cloud — Deep experience with AWS (ECS/Fargate, Lambda, EventBridge, SQS, S3); strong proficiency with Terraform for Infrastructure-as-Code and GitLab CI/CD
- Distributed Systems — Experience designing event-driven architectures and managing asynchronous processing at scale; sound judgment on eventual consistency, idempotency, and failure handling
- Technical Leadership — Demonstrated experience at the Staff level: writing ADRs, driving design across a team, and building for compliance-regulated environments (FedRAMP / SOC 2 / ISO 27001)
- AI-assisted development — Comfortable using modern AI coding tools (e.g., Claude / Claude Code) to accelerate delivery, review, and problem-solving; we actively embrace these tools and value engineers who use them thoughtfully to raise both speed and quality, and who help their teams do the same

## Preferred / Nice-to-Have

- Experience leading a front-end framework migration end-to-end
- Deep experience scaling production Rails under real traffic
- Serverless background-processing frameworks at scale
- DynamoDB / Redis data modeling for high-throughput workloads
- Familiarity with compliance-regulated environments (FedRAMP, SOC 2, ISO 27001)
- Track record of integrating AI tooling into team engineering workflows (code generation, review, test scaffolding, automation)

Education & Experience

- BS or equivalent plus 10 years of experience
- MS or equivalent plus 5 years of experience
- Ph.D. or equivalent plus 4 years of experience

We offer company-wide bonuses based on monthly sales targets, employee referral bonuses, adoption assistance, tuition reimbursement, certification reimbursement, and certification completion bonuses - all in a modern, high-tech, and fun work environment.
