  • Deep understanding of Generative AI and LLM-based systems
  • Strong experience with RAG pipelines and Vector Databases (Pinecone, FAISS, ChromaDB, Weaviate)
  • Solid knowledge of Agentic AI — building autonomous agents and multi-agent workflows
  • Proficiency in AWS or GCP in production environments
  • Experience with distributed systems, microservices, and system design
  • Strong grasp of Data Structures, Algorithms, and Design Patterns
  • Familiarity with WebSockets, Git, Linux/Unix, and CI/CD

Nice to Have

  • Experience with Anthropic Claude API and Claude Code
  • Familiarity with real-time data systems or streaming (Kafka, etc.)
  • MLOps and AI system lifecycle experience
  • Optimizing AI systems for latency, cost, and scalability

Who You Are

  • You think in systems, not just features
  • You take full ownership of what you build
  • You are comfortable navigating fast-moving, ambiguous environments
  • You stay updated with the latest in Generative AI and backend technologies
  • Strong communicator who can collaborate across teams and global clients

What We Offer

  • Competitive compensation (Best in Industry)
  • Work on production-grade AI systems used by global clients

About the Role

You will work as an AI Architect who designs the systems behind our client engagements: AI agents, RAG systems, automation platforms, and the conventional backend systems around them.

This is a hands-on design role, not a slideware role. You will scope architectures with clients, make the hard technical decisions, defend them in review, and stay accountable for how the systems perform in production.


You will work directly with clients. Everyone at KnackLabs does. You will sit in design discussions with client engineering teams, present architecture decisions to technical and business stakeholders, and answer for the choices you make.


A full KnackLabs engineering team in Hyderabad builds with you. You own the technical design and the quality of what ships.

What you'll own

  1. Architecture - Design AI agents, RAG systems, integrations, and the scalable backend systems around them, for multiple client engagements.
  2. Technical scoping - Work directly with clients to turn a business problem into a system design, with clear trade-offs and clear reasons.
  3. Scale and reliability - Make sure what we build handles real load: data stores, queues, caching, horizontal scaling, and fault tolerance.
  4. Design reviews - Review designs and builds across engagements. Set the technical bar and hold it.
  5. Evaluation strategy - Define how we measure accuracy, safety, latency, and cost for the AI systems we ship.
  6. Guiding engineers - Raise the level of the engineers building with you, through reviews and direct pairing.
  7. Feedback to the platform - Feed what you learn across engagements back into our platform and internal tools.

What we are looking for

  1. Around 7 or more years of software engineering experience, including direct work with customers on design or delivery.
  2. Full-stack development experience with strength in backend technologies.
  3. Experience designing and building scalable applications. You understand how large-scale distributed systems work: data partitioning, queues, caching, horizontal scaling, and fault tolerance.
  4. At least 2 years of strong, hands-on AI experience with large language models in production.
  5. You build with AI coding tools like Claude Code or Codex as your default way of working. You understand Claude Skills, have written skills yourself, use them actively, and have contributed to them.
  6. Hands-on experience building retrieval-augmented generation (RAG) systems: chunking, embeddings, vector databases, retrieval, and reranking.
  7. Hands-on experience building AI agents.
  8. Strong programming skills in Python. Working knowledge of TypeScript or JavaScript.
  9. Experience with at least one cloud platform (AWS, Azure, or GCP).
  10. Clear communication. You can explain an architecture decision to an engineer and to a business leader, and defend it under questioning.
  11. High ownership and comfort with ambiguity. You can take an unclear problem and turn it into a design.

Nice to have

  1. Experience building evaluations to measure accuracy, safety, latency, and cost.
  2. Experience with observability and tracing tools such as LangSmith or Braintrust.
  3. Experience with on-premises or private cloud (VPC) deployments.
  4. Experience deploying AI systems in regulated industries such as insurance, banking, or the public sector.
  5. Experience with data engineering and pipelines.
  6. A history of side projects, open source contributions, or products you shipped end-to-end.
  7. Experience working at a consulting or professional services firm in a client-facing delivery role.

Stack and tools

  1. Languages: Python and TypeScript.
  2. Models: Claude and other frontier or open-source models, chosen to fit the customer.
  3. AI patterns: RAG, agents, prompt engineering, skills, and evaluations.
  4. Vector and retrieval: vector databases and retrieval pipelines.
  5. Cloud: AWS, Azure, or GCP, on public or private cloud.
  6. Integration: REST APIs and enterprise system connectors.

Senior AI Engineer

Code Generation, Agent Architecture & LLM Systems

📍 Mumbai (On-site) | Full-time | 5+ years


About the Role:

Unico Connect is an AI-first technology partner that builds custom mobile, web, and AI products for clients across multiple geographies.

We are hiring a Senior AI Engineer for a dedicated client engagement focused on building an AI-powered application builder platform - a product where users describe software in plain English and the system generates, previews, and iteratively refines working code.

The mandatory requirement for this role is hands-on production experience shipping LLM-powered systems with agent architectures, with experience in code generation or developer tooling contexts a strong advantage.


The role is product-focused and deeply hands-on. You will own everything between the user's prompt and correct code landing in the project: the agentic loop, code generation pipeline, context management, evaluation suite, and model cost strategy.

You will work alongside the Senior MLOps Engineer who operationalises the infrastructure around your system, and collaborate closely with backend, frontend, and DevOps engineers.


Responsibilities:


Agent Architecture

Design and own the agentic loop for the platform - request interpretation, planning, tool-calling sequence (read file, edit file, run build, search code, install package), and stop conditions.

Make and revisit architectural decisions on single-agent vs. multi-agent designs, including planner/executor splits and dedicated build-repair sub-agents.


Code Generation Pipeline

Own the end-to-end generation flow: task classification, context gathering, planning, targeted edits, verification, and commit.

Implement diff/search-replace-based file editing with fuzzy matching and fallback strategies.

Enforce scope discipline so the agent makes minimal diffs and does not modify code it was not asked to touch.


Self-Repair Loop

Build and tune the automated repair loop that pipes compiler, lint, build, and runtime errors back to the model with retry budgets and model escalation.

This loop is the primary quality lever - the difference between 60-70% and 90%+ build success rates.


Context Management

Build file-relevance retrieval so the agent sees the right files, not the whole codebase: dependency graphs, AST/tree-sitter-based chunking, embeddings, recency signals, and hybrid retrieval.

Implement conversation summarisation and memory for long sessions, and address long-project degradation through codebase summaries and periodic consistency passes.

Own token budgeting and prompt caching strategy.


Prompt Engineering as a Discipline

Own the system prompt and per-task prompt variants (new feature, bug fix, styling change).

Maintain few-shot examples and enforce coding conventions, stack rules, and prohibited behaviours such as no hardcoded secrets and no whole-file rewrites.

Version prompts like code with changelogs and rollback capability.


Evaluation and Quality Measurement

Design and own the evaluation suite: representative test prompts run on every prompt and model change, scored on build success rate, instruction adherence, and output quality including LLM-as-judge and visual/screenshot checks where relevant.

Define regression gates that block quality-degrading changes from shipping.

Treat evals the way engineers treat automated testing: versioned, automated, and tracked over time.

This responsibility is non-negotiable at this level.


Model Strategy and Cost

Design model routing - cheap and fast models for classification and small edits, frontier models for complex generation.

Drive cost optimisation through prompt caching, diff-based edits over full-file rewrites, and tighter context selection.

Track cost per agent run and tokens per task; evaluate new model releases against the eval suite and lead migrations when results justify it.


Safety and Reliability of Agent Behaviour

Defend against prompt injection from user content and fetched web content.

Ensure secrets never appear in generated client code.

Define what the agent's tools may and may not do in collaboration with the platform team.

Contribute to output moderation and abuse-pattern awareness.


Mentorship and Engineering Standards

Run code reviews, define engineering conventions for AI work, and raise the engineering bar across the AI team.

Work closely with the Senior MLOps Engineer on handoff of eval design, prompt configurations, and model routing logic.


Requirements:


Hands-on Production Ownership of LLM-Powered Systems with Agent Architectures (Mandatory)

Must have personally shipped and operated at least one complex production AI system - agentic, multi-step, or code generation - with end-to-end ownership of architecture, evaluation, and cost.

POCs, internal demos, and tutorial-grade work do not qualify.


5+ Years of Professional Software or AI Engineering Experience

With at least 3 years focused on LLM applications, AI engineering, or production AI systems.

Candidates with strong backend backgrounds and a clear, substantive pivot into LLM systems qualify.


Strong Python Proficiency and Service Development

Production-grade Python with FastAPI or equivalent: type hints, async patterns, streaming responses, testing, and packaging.

Not notebook-only.


Depth Across LLM APIs and Agent Systems

Production experience with at least two of OpenAI, Anthropic Claude, Google Gemini, or open-weight models (vLLM, Ollama, Together).

Production experience with at least one agent framework (LangGraph, CrewAI, AutoGen, LlamaIndex Agents) or hand-rolled equivalent.

Hands-on with tool calling, structured outputs, and multi-step reasoning.


Demonstrated, Systematic Evaluation Practice - Non-Negotiable

Must have built evaluation harnesses that gate production releases, not ad-hoc testing.

Hands-on with at least one of LangSmith, Langfuse, Promptfoo, Ragas, or DeepEval.

Candidates with no systematic answer to evaluation should not be considered at senior level regardless of other strengths.


Cost Discipline for Production AI

Track record of measurable cost optimisation on production AI features.

Able to speak in specifics: cost per request, savings achieved through caching or model routing, context reduction decisions.
