About Bland

At Bland.com, our mission is to empower enterprises to build AI phone agents at scale. Voice is quickly becoming the primary interface between businesses and their customers, and we are building the models and infrastructure that make those interactions feel natural, reliable, and genuinely human.

We’ve raised $65M from leading investors including Emergence Capital, Scale Venture Partners, Y Combinator, and founders of Twilio, Affirm, and ElevenLabs.

The Role: Research Engineer

We are looking for someone to spearhead the development of our next-generation multimodal LLM stack, combining speech, text, tools, and real-time reasoning into a single unified system. You’ll be responsible for building industry-leading conversational AI models that power Bland's agent, and taking them all the way from idea to production.

At Bland, we're not just thinking about text modeling. You will define how our agents listen, think, and act in real time, integrating streaming audio, tool execution, and dynamic context into a single coherent system.

This role sits at the intersection of:

• LLM architecture and fine-tuning

• real-time speech systems

• agent design (prompting + tools + policies)

• multimodal reasoning (audio + text + actions)

You will take ideas from research through production systems serving millions of calls per day.

What Makes You a Great Fit

Strong LLM / Multimodal Background

• Experience with LLMs, multimodal models, or speech-language systems

• Deep understanding of prompting, fine-tuning, and alignment techniques

• Familiarity with streaming or real-time inference is a strong plus

Systems Thinking

• Ability to reason about full systems, not just models

• Comfortable designing interactions between:

  • model

  • tools

  • prompts

  • runtime constraints

Fast Experimental Loop

• You can go from idea → dataset → experiment → conclusion in days

• You know how to design experiments that actually answer the question

Product Intuition

• Strong sense for what makes an interaction feel natural vs robotic

• Ability to translate abstract modeling ideas into user-facing improvements

Builder Mentality

• You take ownership from research through deployment

• You thrive in ambiguous, fast-moving environments

• You care about impact, not just elegance

How You Show Up

• You think in systems, not just models

• You obsess over latency, correctness, and real-world behavior

• You are comfortable discarding ideas quickly when data disagrees

• You push toward simple abstractions for complex problems

Bonus Points

• Experience with real-time voice systems or conversational AI

• Background in tool-using agents or agent frameworks

• Experience with multimodal datasets (audio + text + actions)

• Contributions to LLM or speech-related research or open source

Why This Role Matters

Your work will define how our agents:

• understand users in real time

• decide when to respond

• choose what tools to call

• balance speed vs correctness

• behave under complex policies

This is the core intelligence layer of the product.

Compensation & Benefits

• Competitive salary: $180,000 – $260,000

• Meaningful equity

• Full healthcare, dental, vision

• Office in Jackson Square, SF

• High autonomy, high impact
