What You’ll Be Building
At KnowBe4, we recognize that cybersecurity has always been a human problem. Our Human Risk Management platform uses intelligent, adaptive systems to help people and AI agents recognize and respond to threats, turning human behavior from the weakest link into the strongest defense.
As a Senior Software Engineer, you’ll design and deliver AI-driven systems that power features used by millions of users around the world. This isn’t prompt-tweaking or proof-of-concept work, it’s full-stack AI engineering at scale, where reliability, explainability, and security matter as much as innovation.
What You’ll Do
- AI Architecture: Design and deliver scalable AI systems that connect models, data, and products.
- Model Integration: Turn research prototypes into secure, reliable, production-ready services.
- Data Orchestration: Build pipelines and serving layers that power adaptive, real-time features.
- Collaboration: Partner with other engineering teams to ensure performance and reliability.
- Frameworks: Create reusable SDKs and libraries that accelerate AI adoption company-wide.
- Excellence: Champion observability, testing, and secure-coding best practices.
- Improvement: Anticipate emerging AI and cloud trends to guide technical evolution.
What You Bring
You’re the kind of engineer who thrives on ownership - taking ideas from concept to production - and believes real innovation happens when engineering discipline meets curiosity.
- 5+ years of experience building and operating large-scale, cloud-native or SaaS systems (preferably in AWS).
- Proficiency in Python and modern API frameworks such as FastAPI or Flask.
- Hands-on experience with CI/CD pipelines (we use GitLab) and infrastructure-as-code (we use Terraform).
- Practical experience delivering AI/ML features - RAG, orchestration, embeddings, or agentic workflows - in production.
- Commitment to engineering quality - you design for reliability, testability, and long-term maintainability.
Bonus points if you have:
- Experience with LLM and orchestration frameworks (LangChain, LangGraph, Hugging Face, PyTorch).
- Familiarity with data processing and analytics tools (PySpark, Polars, or Parquet).
- A habit of turning new discoveries into reusable knowledge for the team.
