AI/ML Engineer

Job Overview

We are building a small, empowered product discovery team focused on Zinkworks’ Autonomous Networks product portfolio. This team will take new product ideas from concept through to high-fidelity working prototypes that telco operators can see, test, and react to.

As our Senior Agentic AI Engineer, you will own the agentic AI execution layer for the team.

This is a hands-on implementation role. You will design agent architectures, build evaluation frameworks, manage prompts and context, and ship agent-driven features to demoable, client-ready quality. The focus is not academic research. It is about applying proven agentic AI patterns quickly, thoughtfully, and to a high engineering standard.

Key Responsibilities

• Build and ship agentic AI layers for new product prototypes.
• Design agent architectures that are reliable, explainable, and fit for purpose.
• Define and manage evaluation frameworks to measure agent quality and performance.
• Own prompt, context, and model selection decisions across the team’s prototypes.
• Select the right model, tool, or approach for each use case and clearly justify the choice.
• Partner with the Senior Backend Engineer on the boundary between agents, APIs, services, and data flows.
• Work with the Senior UI Engineer to explore agentic and post-GUI user experience patterns.
• Iterate quickly based on feedback from internal stakeholders, technical experts, and customer-facing teams.
• Feed practical learnings back into Zinkworks’ AI and Solution Architecture teams to support product strategy and roadmap decisions.
• Maintain a strong engineering quality bar while working in a fast-moving product discovery environment.

Required Qualifications

We are looking for a senior engineer with a strong track record of building agentic AI systems in production or near-production environments.

You should be comfortable designing, implementing, testing, and improving AI agents that can interact with tools, systems, APIs, and users. You will understand the trade-offs between prompt engineering, retrieval, fine-tuning, stronger model selection, and traditional software logic.

You are an implementer first. You know how to take modern AI capabilities and turn them into working software that is reliable enough to demonstrate, evaluate, and improve.

Key Skills and Experience

• Strong Python engineering experience.
• Proven experience building agentic AI systems in production or near-production settings.
• Strong understanding of agent architectures, tool-using agents, and multi-step AI workflows.
• Experience designing or implementing evaluation frameworks for LLM or agentic systems.
• Strong prompt engineering, context engineering, and model selection experience.
• Experience working with cloud-based AI services, ideally on GCP.
• Familiarity with Vertex AI and modern LLM tooling across different providers.
• Ability to work closely with backend engineers on agent/server integration.
• Strong engineering judgement and the ability to choose simple, practical solutions over unnecessary complexity.
• Comfortable working in a fast-moving product discovery or prototyping environment.

Nice to Have

• Experience with Google ADK.
• Experience building multi-agent systems.
• Experience with tool-calling agents and agent orchestration.
• Exposure to telecoms, network operations, OSS, or autonomous networks.
• Experience contributing to AI product strategy through practical delivery learnings.

Tech You’ll Work With

• Python
• Google ADK
• GCP
• Vertex AI
• Modern LLM tooling across multiple providers
• Agent evaluation frameworks
• Prompt and context management approaches
• APIs, data services, and cloud-native backend systems

We are deliberately pragmatic about model and tooling choices. Fitness for purpose matters more than loyalty to any one provider, framework, or architecture.
