At Klue, We’re Building the Future of Competitive Intelligence

👋 Klue Engineering is hiring!

We're looking for a Software Engineer with production experience to join our Toronto AI engineering team. You'll help us build and improve the LLM-powered agent systems that turn millions of competitive data points (news, press releases, webpage changes, Slack posts, emails, reviews, CRM data) into actionable intelligence for our customers.
This is a hands-on builder role. You'll ship code into our agent stack from week one , pairing with senior engineers, owning well-scoped pieces of larger projects, and growing into bigger ownership over time. If you've shipped a backend system at one prior role and you're excited to go deep on retrieval, RAG, and agent infrastructure, we want to talk to you.

What You'll Build

You'll contribute across our core AI services:

Ambient Agents of Klue. Our agent runtime. Scheduled and event triggered agents. You might add a new pipeline stage, build a new scheduled agent, improve tooling, or harden an existing workflow.

Multi-agent orchestrator. A service coordinating agents that talk to data exclusively through MCP servers. You might wire up a new MCP tool, improve prompts and streaming behavior, evaluate chat quality, or extend an agent.

Search and retrieval layer. Our query layer over all of Klue's data. You might add a new index, improve a query endpoint, tune chunking for better retrieval, or extend an MCP tool used by agents.

In your first six months, you'll ship small, well-scoped tickets under mentorship, take ownership of a feature end-to-end, then start contributing to bigger initiatives.

What You'll Do
Ship backend code that powers our agents. Build and modify agent services, workflows, and MCP tools.

Help improve retrieval and ranking. Pair with senior engineers on hybrid retrieval, query rewriting, chunking strategies, and re-ranking. Bring your curiosity about BM25 vs. dense vs. hybrid retrieval and we'll teach you the rest.

Write and run evaluations. Come up with ways to evaluate agent performance. Eval rigor is a core part of our workflows.

Improve LLM-powered workflows. Tweak prompts, adjust retrieval parameters, add caching, reduce latency and measure the impact in production

Care about reliability. Write tests, watch deploys, follow up on errors in our monitoring tools and leave the code better than you found it.

Collaborate. You'll work closely with senior ICs, our product team, and other engineers across infra and data. Ask questions early, get feedback often, and share what you learn.

What You Bring

Must Have:

Production software engineering experience. You've shipped real code at one prior role, features that customers used, with code review, deploys, and on-call (or equivalent ownership).

Strong Python fundamentals. You're comfortable with modern Python: type hints, async/await, FastAPI or a similar framework, SQLAlchemy or another ORM, pytest. You write clean, readable, well-tested code.

Curiosity about LLMs, RAG, and agentic systems. You've built side projects, taken courses, or worked with LLMs in some capacity, even if not in production. You can explain what RAG is, you've used an LLM API, and you're excited to go deeper.

Solid CS fundamentals. You understand HTTP, databases, basic distributed systems concepts, and the tradeoffs involved in building reliable services.

Comfort with cloud and containerized environments. You've worked with Docker and have deployed something to AWS / GCP / Azure (we use GCP and Kubernetes, exposure is great, expertise not required).

You use AI coding tools to accelerate your work. Copilot, Cursor, Claude Code, or similar and you can talk about what they're good at and where they fall short.

Customer-oriented mindset. You care about who's using what you ship and why. You ask "what's this actually for?" before "how should I build it?".

Ownership and growth mindset. You take small projects across the finish line. You ask for feedback and act on it. You don't wait for someone to hand you the next thing, you go find it.

Nice to Have:

Hands-on experience with any of: Elasticsearch / OpenSearch, vector DBs (Pinecone, PGVector, FAISS, Weaviate), Temporal, Pydantic-AI, fastmcp, or LangChain.

Exposure to MLOps tooling (Logfire, Langfuse).

A side project or open-source contribution involving LLMs, retrieval, or agents, we love seeing what you build on your own time.

Experience writing evaluations for LLM systems.

Background in information retrieval, search, or NLP from school or work.

What Success Looks Like
In your first 30 days you'll have your dev environment running, shipped your first PR, and started picking up small bugs and features in one of our three core repos. By 90 days you'll be owning bite-sized features end-to-end and contributing to design conversations. By 6 months you'll be a trusted contributor others come to with questions about the part of the stack you've grown into.

We're looking for builders who:

Take ownership of well-scoped problems and run them to completion

Ask great questions and aren't afraid to say "I don't know yet"

Bring scientific rigor while staying pragmatic about delivery

See unclear requirements as an opportunity to clarify, not a blocker
