🚀 AI Developer (Agentic Systems)

Phoeniqs Technologies | Build the Future of Autonomous Intelligence

At Phoeniqs Technologies , we’re not just integrating AI into systems — we’re engineering intelligence that can think, plan, collaborate, and act.

We’re looking for a forward-thinking AI Developer to help us design and scale the next generation of goal-driven, autonomous AI agents capable of multi‑step reasoning, tool usage, and continuous self‑improvement. If you’re passionate about agent architectures, prompt engineering, and modular AI orchestration — and want to ship real-world AI systems that actually do things — this is your role.

🌟 What You’ll Be Building

You’ll work at the frontier of applied AI, developing production-grade agentic systems that can:

• Make decisions

• Plan and execute complex tasks

• Collaborate with other agents

• Learn from memory

• Interact with tools, APIs, and real-world environments

From research agents to coding copilots and planning assistants — your work will power intelligent systems that move from response-based AI → action-based autonomy .

🛠️ Your Impact

• Architect and develop agentic AI systems using frameworks like LangChain, AutoGen, DSPy, CrewAI or custom orchestration layers

• Design modular, goal-oriented workflows for autonomous task planning and inter-agent collaboration

• Implement advanced agent patterns including:

• Planner–Executor loops

• ReAct

• Reflection & Self‑Verification

• Engineer sophisticated prompting strategies:

• Chain-of-Thought

• Tree-of-Thought

• Structured outputs

• Prompt versioning

• Build persistent memory systems (short-term, long-term, episodic)

• Integrate LLMs (OpenAI, Anthropic, Cohere, Mistral, DeepSeek, OSS models) with execution environments:

• Python

• Bash

• SQL

• REST APIs

• Browser automation

• Design and optimize RAG pipelines with vector databases and hybrid search

• Implement API orchestration, tool calling, and code execution agents

• Deploy scalable AI systems using Docker, CI/CD, and cloud platforms

• Monitor agent behavior, execution traces, and reasoning paths

• Implement human-in-the-loop workflows to ensure safe autonomy

• Collaborate with Product, Engineering, Data Science, and UX teams to deliver high-impact AI solutions

✅ What You Bring

• 3+ years in Software Engineering or Applied AI

• Strong Python skills

• Hands-on experience with agent frameworks such as: LangChain, DSPy, AutoGen, CrewAI (or equivalent)

• Deep understanding of agent design patterns:, Planner/Executor, Memory & Reflection loops, Tool selection, Self-evaluation

• Expertise in prompt engineering, including: Chain‑of‑Thought, ReAct, Structured prompting, Output validation

• Experience building RAG systems : Chunking strategies Embedding optimization Retrieval tuning

• Experience with vector DBs: FAISS, Pinecon ,Weaviate, OpenSearch

• LLM deployment via APIs or open-source models (e.g. LLaMA, Mistral, Qwen, DeepSeek)

• Familiarity with inference frameworks: vLLM, TGI, Ollama

• Tool integration experience: REST APIs, Databases, File systems, Browser automation

• Working knowledge of: Docker, Git, AWS / GCP / Azure

✨ Bonus Points

• Built AI copilots, taskbots, or autonomous agents in production

• Experience with observability & safety tooling:

• Guardrails AI

• Rebuff

• HoneyHive

• Model routing & dynamic model selection

• Context window optimisation

• Fine-tuning techniques (LoRA, QLoRA)

• Contributions to open-source agent or LLM tooling

• Familiarity with:

• Prompt injection mitigation

• Alignment strategies

• AI safety best practices

🔥 Why Phoeniqs?

At Phoeniqs Technologies, you’ll work on cutting-edge AI systems that move beyond chat into execution and autonomy. We believe the future of software is agent-driven , and we’re building the orchestration layer that makes it real.

If you’re excited by the idea of AI systems that don’t just assist — but act — we’d love to meet you.
