Senior Software Engineer

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)
