This position offers the chance to directly influence the evolution of customer experience through the development of high-impact AI agents. These agents are designed to operate autonomously across multiple industries, from finance to healthcare to travel, delivering reliable support and intelligent action in place of traditional customer service teams.
You will be joining a group of engineers who focus on delivering real functionality. You will help build systems that not only respond but anticipate, interpret, and resolve complex customer needs. These AI agents handle real transactions and high-sensitivity tasks, from resetting passwords and updating personal details to navigating nuanced account issues or completing bookings.
This role emphasizes full-cycle ownership. You will take ideas from concept through design and into production. Engineers here work directly with customer-facing teams to gather context, identify pain points, and rapidly prototype improvements that make measurable differences. You will collaborate closely with other engineers, product managers, and operations teams to create agents that are resilient, clear in their logic, and deeply integrated with real-world workflows.

Design and build AI-driven agents that can outperform human representatives in efficiency, accuracy, and user satisfaction across both voice and chat platforms.
Translate natural language instructions into structured workflows using a unique agent logic framework that blends linguistic flexibility with software-grade precision.
Analyze performance data to uncover trends and identify opportunities for large-scale improvements to both platform capabilities and agent behaviors.
Experiment with the latest advancements in voice and language models, integrating and tuning them for enterprise reliability, responsiveness, and language coverage.
Use real-time observability tools to trace every decision made by an agent, ensuring systems can be audited, understood, and rapidly improved without guesswork.
Qualifications
What You Bring
At least two years of experience as a professional software engineer, working on production systems with real users.
A high level of fluency in Python and TypeScript, including comfort with asynchronous operations, error handling, and performance tuning.
Strong troubleshooting skills with the ability to dig into complex tech stacks and resolve problems using the best tool for the job, whether that's a profiler, a log aggregator, or raw data inspection.
A proactive mindset and a deep curiosity about how AI agents think, how they fail, and how to make them more intelligent and dependable.
Open on programming language experience.
Looking for people who have a computer science degree from a strong school.
Willing to teach everything someone needs to know about AI.
Additional Experience That Helps
Exposure to multimodal AI systems or voice interface development.
Familiarity with enterprise-scale customer experience platforms or conversational automation frameworks.
Interest in designing tools that make agent behavior transparent, especially through visualization, testing, and simulation infrastructure.
Perks and Benefits
Competitive salary with equity options for long-term ownership.

Software Engineer
Software engineer job in Fremont, CA
As a software engineer at General Medicine, you'll help build and scale a healthcare store that makes it delightfully simple to shop for any type of care. We provide upfront cash and insurance prices for virtual and in-person visits, prescriptions, labs, imaging, and more.
What we're looking for
We're looking for strong engineers to help us build a seamless and beautiful consumer healthcare product. We're looking for folks who will obsess over every detail of our patient experience, and also tackle the complex operational challenges of delivering care at scale. We are looking for engineers who care deeply about technical excellence but are also comfortable moving quickly - we are constantly navigating tradeoffs between engineering velocity and quality.
Our ideal candidate is hungry, high-agency, and aspires to be a generalist. Our engineers frequently write product requirements documents, write SQL to understand how features are performing, and own QA - no task is beneath us or outside of the scope of the role if it helps us to deliver a great product. We're looking for someone who can operate in an environment of significant ambiguity, and who is comfortable working closely with design, operations, and clinical stakeholders.
We don't expect you to have a healthcare background (though it's great if you do!). However, you should be excited by the prospect of digging into the messy complexities of the American healthcare system (integrating with EHRs, revenue cycle management, etc).
Qualifications
2+ years of experience building web apps as a full-stack engineer
Experience with modern infra tooling and programming languages. We currently use AWS, Ruby on Rails, and NextJS, and would expect you to have proficiency in a modern tech stack even if it isn't the one we are using.
Please note that this role is based in either our SF office (near Market and Spear St) or our Boston office (Central Square, Cambridge). We expect our team to work from the office least 3 days per week.
Why join us
We're an experienced team that has built a company in this space before, our product has clear product-market fit, and we've raised money from top investors.
We have an ambitious and distinctive vision for what can be built in consumer healthcare. We believe LLMs and price transparency legislation have opened up several massive opportunities.
If you're an ambitious and entrepreneurial software engineer and this resonates, please apply.
