Senior AI Engineer; Backend & AI Systems

About GTT

GTT is a leading networking and security as a service provider for multinational organizations, simply and securely connecting people and machines to data and applications – anywhere in the world. We serve thousands of organizations, bringing together the right people, partners and technology to reduce the burden on IT teams and solve the most pressing networking and security challenges. Built on our top-ranked global Tier 1 network, GTT Envision is a single global technology platform to connect, orchestrate, virtualize and automate enterprise networks, enabling customers with consumable solutions to achieve business missions and meet ongoing demand when, where and how needed.

Our portfolio includes SASE, SD‑WAN, security, internet, voice and other connectivity options, complemented by a suite of professional services and exceptional sales and support teams in local markets around the globe. We partner with our customers to deliver Greater Technology Together.

We are a small, highly focused team building a sophisticated, modular AI platform designed to automate and reason through complex business and technical challenges. Our vision is to create a powerful assistant that is both intelligent and extensible.

Our development philosophy is centered on a clean, service-oriented architecture. We are building a system where a central AI orchestrator communicates with a growing ecosystem of specialized tools via a robust gRPC-based fabric. We leverage a modern data stack (Postgre

SQL and Vector Databases) and integrate powerful Large Language Models (like NVIDIA NIM and open‑source alternatives) to form the system's core intelligence. This is a ground‑floor opportunity to join as a foundational engineering partner and help shape the future of this ambitious platform.

AI‑Augmented Engineering (
Vibe Coding
)

Our development process is uniquely modern. We build in a close partnership with a sophisticated AI assistant in a workflow we call "Vibe Coding".

This elevates the role of the engineer. Instead of spending most of your time on manual, line‑by‑line coding, you will focus on:

• Architectural Guidance: Directing the AI with high‑level goals, architectural patterns, and the "vibe" of what needs to be built.
• Expert Review & Integration: Critically reviewing AI‑generated code for correctness, efficiency, and adherence to our standards, then weaving it into the broader system.
• Rapid Iteration: Leveraging AI to prototype, build, and refactor complex components at a speed impossible with traditional methods.

The core skill set shifts from being a writer of code to a director of code. If you are excited by the idea of being a force‑multiplier who guides AI to build software, you will thrive here.

As a key member of our founding team, you will play a critical role in developing the core backend and AI capabilities of our platform. Your work will be varied and fundamental to our success:

• Build the Backend Fabric: Guide the AI‑augmented development of high‑performance, modular Python services that form the backbone of our ecosystem.
• Architect API‑Driven Communication: Implement and evolve the gRPC‑based APIs that enable seamless, efficient communication between the orchestrator and its various tools.
• Orchestrate AI & LLMs: Integrate and harness Large Language Models to drive complex workflows, tool selection, and advanced reasoning capabilities.
• Develop Scalable Data Strategies: Architect and manage our data persistence layer, combining the strengths of relational (Postgre
  
  SQL) and vector (Chroma
  
  DB) databases.
• Create Robust Data Pipelines: Build and optimize the data ingestion and processing pipelines that continuously enrich our AI's knowledge base.
• Collaborate on Core Architecture: Work directly with the Lead Architect to solve challenging technical problems, make key design decisions, and guide the platform's technical direction.

We're looking for a talented and versatile backend engineer who is passionate about building well‑architected systems and is excited by the creative possibilities of modern, AI‑driven development.
