This role is hybrid in nature with the Engineer able to commute into the Frisco, TX office 3-4 days/week.

About the Role:

• Design and Develop: Lead the design and engineering of our Cloud Threat Detection Platform, driving core submission pipelines, high-throughput microservices, dynamic sandbox execution, and platform features from concept to production.

• Full-Stack & Web UI: Build modern, responsive web application interfaces and analyst dashboards using React, Django, HTML, CSS, JavaScript, Bootstrap, AJAX, and jQuery.

• High-Volume Submission Pipelines: Architect resilient microservices and asynchronous processing pipelines capable of handling millions of API submission requests daily with low latency.

• End-to-End AWS Infrastructure: Design, deploy, and manage secure AWS cloud environments leveraging VPC architecture, NAT Gateways, Security Groups, EC2 fleets, Load Balancers (ALB/ELB), EFS, Lambda, API Gateway, ECS, EKS, WAF, and S3 lifecycle management.

• AI-Assisted Engineering: Leverage modern AI tools (including Claude Code, Amazon Q, and LLMs) to streamline code development, automate pull request and code reviews, accelerate debugging, and optimize software delivery lifecycle workflows.

• Identity & Security: Implement secure API boundaries, security exchange protocols, and identity mechanisms using OAuth2, JWT, SAML, and token exchange routines.

• Compliance & Sovereignty Boundaries: Enforce secure multi-region data architecture complying with FedRAMP, US, EU, APJ, and Canadian regulatory and data residency guidelines.

• Observability & Telemetry: Design telemetry pipelines to capture, process, and visualize customer data telemetry, product health metrics, and engine-level telemetry using OpenSearch, DynamoDB, RDS, and Athena.

• Ensure Resilience & Compliance: Ensure applications are highly resilient and secure, following strict Secure Development Lifecycle (SDL) practices, vulnerability assessments, and FedRAMP security boundary requirements.

• Technical Ownership & Reliability: Author detailed design docs and IaC specs while owning production issues end-to-end, including triage, root cause analysis, and SLA commitments.

About You:

• Experience: 11+ years of professional software development experience building and operating high-throughput microservices, cloud platforms, and full-stack web architectures.

• AWS Cloud Expertise (Must-Have): Deep, expert-level knowledge of AWS cloud architecture, compute, networking, security, and storage services for large-scale enterprise systems.

• Operating Systems: Linux proficiency is a must; Shell scripting required.

• Core Development Skills:

• Excellent development and debugging skills in Python (FastAPI, Django, Flask)

• Strong grasp of data structures, design patterns, REST, and async Web APIs handling millions of requests

• Working knowledge of C and C++ for interfacing with low-level inspection engines and execution runtimes (Go preferred)

• CI/CD pipeline and IaC experience (GitHub Actions, Terraform, AWS CDK, CloudFormation)

• Web UI & Full-Stack: Full-stack expertise with Python Django, React, JavaScript, HTML, CSS, Bootstrap, AJAX, and jQuery.

• AWS Core Infrastructure: Hands-on experience with VPCs, NAT Gateways, Security Groups, EC2 fleets, Load Balancers, S3, EFS, Lambda, API Gateway, ECS, EKS, WAF, Docker, RDS, DynamoDB, OpenSearch, Athena, and Redis.

• Compliance Knowledge: Working knowledge of regional data isolation, privacy, and regulatory controls across US (FedRAMP), EU, APJ, and Canada.

• AI Tooling & Code Intelligence: Practical experience integrating AI tooling (e.g., Claude Code, Amazon Q) into daily software development, code generation, refactoring and automated code review workflows.

• Identity & Security: Solid understanding of OAuth2, JWT, SAML.

• Domain Knowledge: Working knowledge of cybersecurity threat detection processes, malware analysis pipelines, and security inspection tools.

• Soft Skills: Excellent written and verbal communication skills with the ability to operate autonomously and collaborate effective across engineering and threat research teams.
