Staff Software Engineer Python & AI Agent Security Platform

Why Join Skyrelis?

• Build the worlds leading AI security & observability platform.
• Work on cutting-edge multi-cloud infrastructure and global PoP architecture.
• Own complex security + cloud problems end-to-end.
• Significant growth opportunity as one of the early engineers building the Skyrelis platform.

About the role

Skyrelis is looking for aMember of Technical Staff (MTS) / Staff Software Backend/Platform Engineercontractor to lead the design and development of cloud-native, Python-first systems that powerAI agents, LLM integrations, safety/guardrails, and secure traffic inspectionacross modern deployments. This is a backend/platform role focused on production systems, security, and reliability.You will work on architecture, core platform services, proxy/HTTP systems, data pipelines, and AI agent runtime controlsshipping production-grade software with high reliability and strong security posture.

Responsibilities

• Leadsystem design and architecture for scalable backend/platform services supporting AI agents and LLM-driven workflows.
• Build and maintainPython services and libraries (APIs, pipelines, policy engines, telemetry, integrations).
• Develop secure, high-performance components involving:
• HTTP/HTTPS , TLS, certificates, and request/response processing
• Forward/explicit proxies , service-to-service traffic interception, and policy enforcement
• Design and implementguardrails/safety controls for AI agent workflows (prompt/response filtering, tool-use controls, policy checks, data loss prevention patterns).
• Build cloud-native deployments onAWS and/or GCP , including CI/CD, observability, and cost-aware scalability.
• Drive debugging and incident resolution: deep dives across app, network, and infra layers.
• Design data models and storage for operational analytics usingOpenSearch/PostgreSQL and related systems.
• Collaborate with product, security, and infra teams to define roadmaps, technical direction, and best practices.
• Mentor engineers and raise engineering quality through reviews, design docs, and operational excellence.

Required Qualifications

• BS/MS in Computer Science, Engineering , or equivalent practical experience.
• 7+ years of hands-on software development experience with strong ownership of production systems.
• Strong background indesign and architecture (distributed systems, APIs, reliability, scaling).
• StrongPython development experience; comfortable with additional languages (e.g.,Go/Java/TypeScript/Rust ).
• 5+ years of working experience with FASTAPI or any other Python web framework.
• Working knowledge ofAWS and/or GCP cloud deployments (networking, compute, IAM, security).
• Excellentdebugging skills across application, network, and infrastructure layers.
• Solid understanding ofHTTP/HTTPS protocols , TLS, certificates, and traffic flows.
• Knowledge/experience withproxies (forward/explicit/reverse), authentication patterns, and request/response transformations.
• Experience with databases and search/analytics systems:PostgreSQL, OpenSearch/Elasticsearch (indexing, mappings, query patterns).

Preferred Qualifications

• Knowledge of AI / LLM / Agent Technology Requirements
• Hands-on experience buildingAI agents using common frameworks (e.g.,LangChain/LangGraph, LlamaIndex, Semantic Kernel ) and core patterns liketool/function calling, planning/execution, memory, RAG, and multi-agent workflows .
• Practical integration withLLM services/APIs (e.g.,OpenAI/Azure OpenAI, Anthropic, Google Vertex/Gemini, AWS Bedrock ) includingstreaming, structured outputs, routing/fallbacks .
• Experience implementing guardrails and safety controls (policy enforcement, prompt-injection defenses, PII/secrets detection, moderation, tool-use restrictions; tools like Prompt Guard, Guardrails AI, NeMo Guardrails, LLM Guard, etc.)
• Strong understanding ofRAG and retrieval systems, includingembeddings, chunking/ranking , and usingvector search (OpenSearch vector, pgvector, Pinecone/Weaviate/Milvus/FAISS).
• Familiarity withevaluation and observability for LLM/agent systems:quality/safety metrics, cost/token tracking, OpenTelemetry tracing/logging .
• Experience buildingsecurity products (DLP, policy enforcement, identity integration, audit logging).
• Experience withservice mesh / sidecars (Istio/Envoy), certificate automation, or SDS/mTLS concepts.
• Experience withKubernetes (EKS/GKE), Terraform/CloudFormation, and production operations.
• Experience withOpenSearch (data streams, index templates, ISM/ILM, dashboards) and performance tuning.

Tech Stack

• Languages: Python (primary), plus Go/Java/TypeScript
• Cloud: AWS/GCP, VPC networking, IAM, load balancers, CDN
• Data: PostgreSQL, OpenSearch, Redis; optional vector DBs
• AI: LangChain/LangGraph, LlamaIndex; OpenAI/Bedrock/Vertex/Gemini/Anthropic
• Observability: OpenTelemetry, logs/metrics/traces, dashboards/alerting
• Security/Networking: HTTP/HTTPS, TLS, proxies, authN/authZ, guardrails

Soft Skills

• Strong ownership and execution abilities.
• Excellent communication and documentation skills.
• Ability to operate independently in a fast-moving startup environment.
• Comfortable collaborating with engineering, security, and customer teams.
