Job description

Why HeyMilo?

HeyMilo is one of the fastest growing AI hiring platforms, backed by prominent investors with strong runway. We’re generating revenue, scaling fast, and building something that’s changing how companies hire.

What are we building?

We’re building the next generation of hiring infrastructure, powered entirely by agentic AI.

Our platform deploys autonomous AI agents that conduct interviews across multiple modalities (voice, video, interview, email), evaluate candidates, and surface insights to recruiters. These agents reason, adapt in real-time, and coordinate with each other across the hiring pipeline. We integrate with 13+ ATS platforms and process thousands of interviews daily; all in production, today.

Who are we looking for?

People who:

• Hold a Bachelor’s degree in Computer Science or Engineering from an accredited North American university
• Genuinely enjoy solving complex engineering problems
• Learn quickly and ship what it takes to deliver results
• Move with urgency; we don’t wait for perfect specs
• Use AI tools (Cursor, Devin) to write code every day
• Want high ownership and production impact from day one
• Value working closely with a tight-knit engineering team

What will you work on?

As a Senior Engineer, you’ll build and ship core features across our platform. Problems you could work on:

Agentic AI systems:

• How do we orchestrate multiple AI agents that coordinate and hand off context to each other?
• How do we build agents that reason and adapt in real-time during live conversations?
• How do we bring hallucination rates down to near zero?
• How do we scale agentic infrastructure to handle 10x concurrent sessions?

Enterprise platform:

• How do we slice and dice insights from thousands of interviews into simple dashboards for recruiters?
• How do we build reliable integrations with dozens of ATS platforms?
• How do we design APIs that scale across thousands of customers?

Data & retrieval:

• How do we build RAG systems for smarter candidate evaluation?
• How do we architect our analytics pipeline across MongoDB, ClickHouse, and InfluxDB?
• How do we improve search relevance with vector embeddings?

What technologies do we use?

• Backend: Python, FastAPI
• Frontend: React, Next.js, TypeScript, Tailwind
• Data: MongoDB, ClickHouse, Redis
• AI/ML: LLMs, RAG pipelines, prompt engineering
• Infra: AWS, GCP, Docker, Kubernetes, SQS

What’s in it for you?

• Take ownership of building the next category-defining AI company
• Collaborate with a tight-knit team of talented builders
• Launch products that directly impact how people get hired
• Competitive salary and equity
• Health benefits, RRSP match, and wellness allowance

This role is not for you if

• You want predictable roadmaps and narrow responsibilities
• You avoid production responsibility
• You prefer process over shipping
