About Us

BluePill builds AI personas that think, behave and react like real customers so that brands can run simulations to test any marketing ideas, messages, ads and campaigns before spending a dollar in the real world. Teams get rich actionable customer insights to go to market with confidence. Backed by Pioneer Square Labs, our team has shipped products at Amazon, AWS AI, and built and sold companies before. We move fast, learn faster, and obsess over building tools customers actually love. Bluepill is already being used by leading brands. If you are excited about building the future of consumer insights and research, literally predict human behavior - let's chat!

What You’ll Do

On any given week you might…

• Invent & prototype. Explore bleeding-edge LLMs and multimodal models to de-risk new persona features and insights workflows.
• Ship production code. Own services & pipelines in TypeScript, Python, and Rust that ingest data, fine-tune models, and serve low-latency inferences.
• Raise the quality bar. Design automated eval suites and human-in-the-loop loops that keep our personas accurate, safe, and bias-checked.
• Set foundations. Make the calls on infra, tooling, CI/CD, and observability so we scale from thousands to millions of personal interactions per day.
• Collaborate cross-functionally. Pair with product, design, and GTM teams to turn fuzzy user problems into lovable AI features.
• Mentor & recruit. Be a force-multiplier for junior engineers and help hire the next five rock-stars on the AI team.

Signs This Role Is For You

• You have tinkered with LLM's, Agents, MCP's. If you have not built any projects using LLM's this role is not for you.
• You’ve shipped production LLM or generative-AI products, not just hack-day demos.
• You’re equally comfortable prompt-crafting, fine-tuning, and profiling GPU memory.
• You sweat over good abstractions and DX, but value shipping over pontificating.
• Talking to early customers energizes you; unknowns and ambiguity don’t scare you.
• You love teaching, writing docs, and leveling-up everyone around you.
• Hands-on with cursor, claude code and other productivity tools

Bonus Points

• Prior experience with RAG architectures, vector DBs, or streaming embeddings.
• Track record navigating enterprise security / SOC2 / GDPR for AI workloads.
• Open-source contributions or published research in NLP / Gen-AI.
• Comfort spinning up infra on AWS, GCP, or Azure with Terraform or Pulumi.
• You’ve grown an engineering org or led a notable open-source community.

Compensation & Benefits

• Salary: $140 – $160k, plus meaningful early-stage equity
• Healthcare: 100 % paid medical, dental, vision for employees 
• Time Off: Self-managed PTO + 2 yearly volunteer days
• Commuter: ORCA pass or parking subsidy (up to $300/mo)
• Gear & Growth: Top-spec laptop of your choice and $1.5 k annual learning stipend
• Culture Perks: Weekly team lunch, quarterly off-sites, and a “build > meeting” mentality

We believe diverse teams build better AI. We welcome every background, identity, and perspective. If you’re excited about the role but don’t meet every bullet, apply anyway—we’d love to meet you.
