Deep experience with FastAPI or equivalent async web frameworks
Solid understanding of relational databases (PostgreSQL preferred), ORM patterns (SQLAlchemy/SQLModel), and schema migration tools (Alembic)
Experience with large-scale data management, including ingesting, normalizing, and persisting high-volume datasets with strong data integrity guarantees
Understanding of long running process design, including retries, progress tracking, and graceful failure handling
Working knowledge of concurrency and distributed execution, and Python trade-offs (asyncio, multiprocessing, task queues)
Ability to design medium complexity systems with clear layering, API contracts, and sound trade-offs
AI Augmented Development
Demonstrated experience using AI coding agents (GitHub Copilot, Cursor, Claude Code, Codex, or similar) beyond autocomplete
Ability to craft structured prompts and instructions aligned with project architecture and conventions
Strong critical evaluation skills to review and refine AI-generated code for security, correctness, and maintainability
Comfort operating in an AI augmented development workflow
Practical understanding of LLM strengths and limitations, knowing when to hand-code vs. delegate to agents
Cloud & Infrastructure
2+ years of experience with AWS, including ECS/Fargate, RDS, ElastiCache, S3, Secrets Manager, IAM, and CloudWatch
Experience with Docker, including multi-stage builds
Familiarity with Infrastructure as Code (Terraform preferred)

Experience with React/TypeScript
Familiarity with cloud security domains (CSPM, threat detection, vulnerability management)
Experience integrating with enterprise APIs (REST, GraphQL, OAuth2/OIDC)
Experience with Snowflake, Databricks, or similar analytical platforms
Familiarity with OpenSearch/Elasticsearch for log analysis and threat hunting
Core Responsibilities
Build and operate security platforms: Design, implement, and maintain backend services and pipelines that ingest, normalize, and analyze cloud security data
Write production-quality code: Deliver clean, tested, well-documented Python services using established architectural patterns
Design medium complexity systems: Own data models, API contracts, orchestration logic, and integrations; iterate designs with team feedback
Leverage AI agents for high output: Use AI coding tools daily, maintaining consistency via structured prompts and skill files
Integrate external data sources: Build reliable integrations with REST, GraphQL, and cloud APIs using secure auth, pagination, and retries
Build resilient data pipelines: Implement multi phase pipelines that handle scale, long runtimes, and partial failures gracefully
Maintain infrastructure as code: Contribute to Terraform modules and CI/CD pipelines
Write automated tests: Maintain strong unit, integration, and end to end test coverage
Conduct thorough code reviews: Evaluate design intent, correctness, security, and long-term maintainability
Collaborate with stakeholders: Work closely with security analysts, platform teams, and leadership
Participate in support rotation: Monitor service health and respond to operational issues
Research and prototype: Evaluate new tools and approaches through rapid prototyping
Document and share knowledge: Maintain documentation, runbooks, and architectural decision records
Additional Expectations
Exercise independent judgment and discretion on matters of significance
Participate in training and knowledge transfer for internal software users
Maintain regular, consistent, and punctual attendance
Skills
python, Terraform, CI/CD, AWS, Cloud Platforms, FastAPI
Additional Skills & Qualifications
Onsite 3 or 4 days
Interview
1st on TEAMS
Coding and systems design interview - 2nd round will be ONSITE - 2 hours
Notes from manager:
Emphasize that this is a software engineering coding team - they exist within Cybersecurity but candidates don't need to be an expert on security; this can be learned on the job
Nice to have -
ML Data Science experience - any experience building ML pipelines
This is primarily a Python role so wants to see development in Python instead of scripts
Candidates were having trouble with a coding screen - 25 minutes solving a problem; candidates using AI to answer questions; needs to be able to think about how to solve problems and talk through how to solve these problems
Any database experience would be good
Strong software eng skills is needed with some experience in Machine Learning
Must have coding experience and able to problem solve on the fly
This is an onsite role so the 2nd interview must be onsite also.
Fast API is primarily used on this team
