Job summary

Blue Machines (Apna) is hiring a Forward Deployed Engineer to bridge software engineering and client delivery, owning production AI agents end-to-end from design to deployment. You will integrate with enterprise systems, optimize agent performance, and lead technical workshops with clients.

You will work across LangChain/OpenAI APIs, REST/WebSocket integrations, and cloud platforms, traveling for on-site reviews and workshops to ensure successful deployments.

Qualifications

• 4–6 years of software development experience with at least 2+ years shipping live LLM/AI applications (agents, RAG, or chatbots).
• Backend proficiency in Python or Java.
• Hands-on experience with cloud platforms (preferably GCP) and APIs, WebSockets, and auth protocols (OAuth2, JWT).
• Data fluency with SQL, Python, or Sheets for data analysis.
• Strong client-facing communication and ability to travel for on-site workshops.

Responsibilities

• Design, build, and deploy production voice AI agents end-to-end with guardrails and tool-calling logic.
• Develop scalable backend integrations (REST, WebSocket, webhooks, CRM writes) to connect with enterprise systems.
• Implement AI orchestration using LangChain/OpenAI or similar SDKs for intelligent workflows.
• Read logs and traces for root-cause analysis across prompt, platform, and data pipelines.
• Monitor agent metrics and run funnel experiments to improve performance and latency.
• Lead technical workshops with client engineering teams and coordinate on-site deployments.

Job description

Blue Machines (Apna) builds production Voice AI for India's largest enterprises—handling millions of live conversations in Hindi, Hinglish, and regional languages. As a Forward Deployed Engineer, you will design, build, integrate, support, and debug production-grade AI agents end-to-end. You are directly responsible for the delivery and execution of your agent, not a partner handing off to it. You will bridge the gap between client systems and the Blue Machines platform across APIs, cloud services, and AI frameworks.

The Role

We are seeking a Forward Deployed Engineer (FDE) who bridges the gap between deep software engineering, cutting edge AI agent orchestration, and client delivery. In this role, you aren't just writing specifications or handing off prototypes you directly design, build, deploy, optimize, and debug production AI agents end-to-end. You will embed deeply with client environments to build seamless integrations while taking full technical ownership of agent performance in the wild.

What You'll Do

• End-to-End AI Agent Architecture: Design, prompt, build, and deploy production voice agents, including guardrails, conversation design, and tool-calling logic.
• Production Integration Engineering: Build scalable backend integrations (REST APIs, WebSockets, webhooks, callbacks, CRM writes) connecting the Blue Machines platform with enterprise systems.
• AI Orchestration & Ecosystems: Implement AI/LLM frameworks using LangChain, OpenAI APIs, or similar SDKs to deliver intelligent workflows.
• System Observability & Root-Cause Analysis: Read system logs, traces, and call flows to run rigorous root-cause analysis—proving whether an issue stems from prompt design, platform layer, or data pipelines.
• Agent Evaluation & Funnel Optimization: Continuously monitor and optimize agent metrics (completion rate, hallucination rate, latency, cost) and run funnel experiments on conversation cadence.
• Client Technical Leadership: Partner directly with client engineering teams, lead technical workshops, manage expectations with clarity, and travel for live-call reviews.

What We Look For

• Core Experience: (4-6) years of software development experience, with at least 2+ years of hands-on experience shipping live LLM/AI applications (agents, RAG, or chatbots; voice experience is a plus).
• Core Backend Skills: Proficiency in Python or Java for backend architecture and integration work.
• Cloud & Web Architecture: Hands-on experience with cloud platforms (preferably GCP) along with deep knowledge of APIs, WebSockets, and auth protocols (OAuth2, JWT).
• Data Fluency: Comfortable pulling and analyzing data independently using SQL, Python, or Sheets.
• Communication & Presence: Strong client-facing communication skills with the ability to explain technical complexities in plain terms.
• Mobility: Willingness to travel for on-site client workshops and deployment reviews.

Nice to Have

• Knowledge of telephony stacks and real-time protocols (SIP, WebRTC, Twilio, Avaya, Ubona).
• Experience with Voice AI or Conversational AI Systems
