About the Team

KnowBe4's Platform Services group is the engineering backbone that the entire product organization runs on. We build the shared infrastructure, APIs, and frontend frameworks that power HRM+ and the growing suite of KnowBe4 products — so that every product team can ship faster, safer, and at scale.

As a Senior Software Engineer on the Core Engineering team, you'll work across the full stack: building Vue 3 micro-frontends, .NET Lambda APIs, and event-driven services on AWS. You'll collaborate closely with product, design, and the engineers shipping the HRM+ console and its integrations — tools that security and HR teams rely on to manage and protect their organizations.

We believe the best engineers own their work end-to-end. That means writing the API, shipping the UI, and wiring the infrastructure — and doing it in a way that the engineer who touches it next says, "this is well done."

What You'll Build

• Micro-frontend applications for HRM+ using Vue 3, TypeScript, and the single-spa framework — from shared navigation components to feature MFEs that compose into the HRM+ shell
• RESTful and GraphQL APIs deployed as AWS Lambda functions in C# (.NET 8/9), backed by DynamoDB, integrated with internal auth and identity services
• Event-driven services that process asynchronous workloads via SQS, including messaging integrations with Slack, Microsoft Teams, and Google Chat
• Shared frontend SDKs and component libraries consumed by multiple product teams — design-system-aligned, versioned, and published to internal NPM registries
• Infrastructure-as-Code using Terraform for multi-environment AWS deployments (dev, staging, production across multiple regions)
• CI/CD pipelines in GitLab CI that build, test, and deploy services to AWS via shared devex pipeline components

Education and Experience

• BS or equivalent plus 8 years of experience
• MS or equivalent plus 3 years of experience
• Ph.D. or equivalent plus 2 years of experience

Essential Responsibilities

• Develops software using the KnowBe4 Software Development Lifecycle and Agile Methodologies
• Recommends solutions to engineering problems
• Assists other team members by providing technical direction
• Defines approaches and solutions to complex technical problems
• Helps to translate KnowBe4's strategic goals into operational plans
• Provides coordination across functional boundaries
• May act as team lead for sub-projects

Technical Requirements

Required

• TypeScript — production experience building and maintaining typed TypeScript applications
• Vue 3 — Composition API, component design, reactivity model, testing with Vitest
• C# / .NET (8+) — building APIs with ASP.NET Core deployed as AWS Lambda functions
• AWS Serverless — Lambda, DynamoDB, SQS, S3, CloudFront, API Gateway, SSM Parameter Store
• REST API design — resource modeling, versioning, error handling, API contracts
• Terraform — writing and maintaining infrastructure-as-code for cloud resources
• GitLab CI/CD — writing pipelines, using shared CI components, multi-environment deployments
• Strong fundamentals — data structures, distributed systems, testing strategies, code review

Preferred / Nice-to-Have

• Micro-frontend architecture — experience with single-spa, module federation, or similar MFE patterns
• Rust — production or personal project experience; strongly encouraged, can be learned on the job
• GraphQL — schema design, resolvers, client-side queries
• Python — scripting or service development, particularly for Lambda or event processing
• Auth/Identity concepts — OIDC, OAuth 2.0, JWT, SSO; understanding of auth flows even without deep implementation experience
• Auth0 or Keycloak — configuration or integration experience
• Vite, pnpm — modern frontend toolchain familiarity
• LocalStack — local AWS service emulation for development and testing
• Contract testing — consumer-driven API contract testing between services (e.g., Pact or equivalent)
