- Implement the Shared Data layer for raw and processed frame exchange across processes with backpressure and safe lifecycle management.
- Integrate and operate CV/AI Engines in Python (preprocess, inference, postprocess) with configurable model loading and runtime selection.
- Develop the Inference Logic layer that orchestrates cropping, batching, filtering, classification, and decision output formatting.
- Implement connectors for Database & Portal (event persistence, evidence references) and for Alerting & Control (events/hooks for downstream automation).
- Ensure production readiness on Linux with observability (logs/metrics), health checks, and robust error handling.

Requirements:
Must-have:
- Strong Python, OOP, clean architecture, typing preferred.
- Solid experience with multiprocessing/concurrency (process lifecycle, IPC patterns, queues/shared memory).
- Comfortable working in Linux (systemd/service mindset, networking basics, profiling/debugging).

- Ability to work with streaming data and reliability constraints (timeouts, retries, resource cleanup).
Should-have:
- Experience with RTSP/RTP streaming and common issues (UDP vs TCP interleaved, jitter, packet loss, camera timeouts).
- Performance optimization (profiling, memory management, zero-copy patterns).
- Exposure to inference acceleration stacks (TensorRT/OpenVINO) or GPU deployment.
- Experience designing event schemas and integration with DB/message queues.

We offer:
- Free English classes with a native speaker and external courses compensation;

• Degree in a quantitative or analytical field such as Mathematics, Economics, or Marketing with a strong analytics focus
• 3+ years of hands-on experience in digital advertising (native ads, Facebook Ads, Google Ads, etc.) with a deep understanding of CPC, CTR, ROMI, and RPC
• AI-native working style with daily use of LLMs and generative tools such as Claude, ChatGPT, Gemini, Midjourney, or similar
• High hypothesis velocity with a focus on systematic testing rather than isolated execution
• Strong analytical thinking with the ability to review large datasets and extract creative patterns that differentiate high-performing campaigns
• Ability to design multi-step prompt chains where the output of one agent becomes the input for another

Nice to have

• Proficiency with competitive intelligence and spy tools such as AdPlexity, Anstrex, or SpyFu
• Experience writing LLM prompts in production environments, including system prompts and few-shot prompting
• Basic SQL or data querying skills
• Familiarity with tracking platforms such as Binom or Voluum
   

Language requirements
English at Upper-Intermediate level or higher. Code, prompts, and data are the primary working languages. No client-facing communication is required.

Title: Principal AI Architect
Location: Remote 
Reports To: Global Head of AI & Advisory

About Atlas Technica

Atlas Technica is the premier Managed Service Provider (MSP) for the alternative investment industry. We power the technology behind the world’s leading hedge funds, private equity firms, and family offices. We are currently evolving into the industry’s first Managed Intelligence Provider (MIP), architecting the secure "factory floor" for institutional alpha generation.

The Opportunity

Generative AI is rewriting the playbook for financial services. For our clients, the risk of "leaking alpha" is just as high as the reward. We have launched a dedicated AI Practice to solve the dual challenge of our industry: How do we enable the power of LLMs (Copilot, ChatGPT, Claude) to generate alpha, without compromising security, compliance, or investor trust?

We are seeking a Principal AI Architect to serve as the technical anchor of this practice. You will not be a cog in a machine; you will be the chief architect of our technical roadmap. You will design our proprietary Tier 2 (Scoped Governance) and Tier 3 (Forensic Compliance) frameworks and oversee the implementation of all bespoke AI projects—including Private Enclaves, MCP Servers, and Agentic Workflows—for our top-tier global clients.

Critical Note: This is primarily a hands-on builder role. While you will have the mandate to mentor and scale a team in 2026, your first 12 months will be spent architecting, scripting, and deploying. If your recent experience has been primarily managing people rather than building technical solutions, this role is not for you.

What You Will Do (The Mission)

• Architect the "Safe Zone" (Tier 2): Design the technical middleware using Microsoft Graph API (Sites.Selected) to solve the "Permission Inheritance Trap." You will build the frameworks that restrict AI tools to curated, pristine data libraries.
• Design Forensic Compliance (Tier 3): Implement enterprise-grade prompt journaling and audit logging. You will architect the integration between LLMs and archival platforms like Global Relay and Smarsh to ensure prompt journaling meets SEC/FINRA standards (Rule 17a-4).
• Lead the Atlas AI Lab: Own our internal sandbox environment. You will design, break, and validate new AI security protocols (e.g., Shadow AI blocking via Cato Networks) before they ever touch a client’s production environment.
• Oversee the "AI Project Machine": Act as the lead architect for bespoke client builds. This includes provisioning Azure AI Foundry enclaves and building Model Context Protocol (MCP) servers to connect LLMs to specialized data sources (e.g., Bloomberg, SQL, BioMedical data).
• Lead Technical Validation: Perform feasibility studies against client tenant infrastructure. You are the "Go/No-Go" gate for technical scoping, ensuring our Bill of Materials (BOM) and hour estimates are accurate.
• Hands-On Execution: Serve as the final escalation point for complex deployments. You will write the PowerShell scripts, configure the Intune MAM policies for mobile AI defense, and build the "Golden Image" for AI-ready tenants.

What You Bring (The Stack)

• Microsoft Ecosystem Mastery: Deep expertise in Microsoft 365, SharePoint Online (unique permissions/broken inheritance), and Entra ID (Conditional Access).
• AI Infrastructure Fluency: Hands-on experience with Azure AI Foundry / Studio, the Azure Model Catalog, and frameworks like LangChain.
• Protocol Knowledge: Familiarity with MCP (Model Context Protocol) to connect LLMs to structured data sources (APIs, Databases).
• Security & Compliance: Expertise in Microsoft Purview (Sensitivity Labels, DLP) and Defender for Cloud Apps. You understand the difference between "logging" a prompt and "blocking" MNPI.
• Scripting & API Chops: Fluent in PowerShell and Python. You know how to manipulate the Graph API programmatically.
• Financial Services Context: Experience in a Hedge Fund, Private Equity firm, or highly regulated MSP is highly desirable. You understand the risk of alpha leakage and the requirements of regulatory audits.

Your First 90 Days

• Month 1: Standardize the "Golden Image" for a Tier 2 Scoped Copilot deployment.
• Month 2: Complete the first live pilot of a "Private Claude" Enclave using Azure AI Foundry.
• Month 3: Scale the "AI Project Machine" by onboarding and mentoring your first Forward Deployed Engineering (FDE) resource.
