Role Summary

We are seeking a Staff Engineer to join one of the engineering teams building Know Be4'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, Svelte Kit), 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 Fed RAMP 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 Svelte Kit 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, Graph QL endpoints, and Vue 3 / Svelte Kit + Type Script 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 Svelte Kit application maintainable
• Graph QL APIs at scale: schema design, batch loading, and query complexity management for high‑traffic, multi‑tenant access patterns
• Event‑driven services: Event Bridge/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 My SQL, Postgre SQL, Dynamo DB, and Redis while maintaining strict tenant isolation and compliance guarantees
• Infrastructure‑as‑Code: Terraform modules and Git Lab 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 Know Be4 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 Know Be4'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 Graph QL (batch loading, complexity management) and relational databases tuning (My SQL/Postgre SQL) for high‑traffic, multi‑tenant systems
• Frontend — Strong proficiency with a modern component framework and strict Type Script; Vue 3 experience is preferred given our MFE direction, and Svelte Kit 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, Event Bridge, SQS, S3); strong proficiency with Terraform for Infrastructure‑as‑Code and Git Lab 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 (Fed RAMP / 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
• Dynamo DB / Redis data modeling for high‑throughput workloads
• Familiarity with compliance‑regulated environments (Fed RAMP, 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

The salary for this position ranges from $170,000-$190,000, which will vary depending on how well an applicant's skills and experience align with the job description listed above.
