About Solidroad
Building something great is addictive. It’s like discovering your favorite TV show mid-season, except you're helping write the next episode. It’s like unboxing a new gadget, except you’re the one designing it. You shape how it feels, how it works, and how people react when they use it.
At Solidroad we're solving a big, messy, exciting problem: how do you scale customer support without losing what makes humans amazing? Warmth, empathy, intuition. We’re using AI, generative tech, and real-time simulations to make this happen. It's ambitious, difficult, and genuinely new.
About the role
We're looking for a senior engineer who sees this role as more than just a job. It should feel like signing up for a job and a hobby. Or a job and a triathlon. Or a job and an advanced language course. You’ll shape our technical decisions, own major parts of our product, mentor your teammates, and push yourself in ways you might not expect. It’ll stretch your skills and fill your life in a deeply rewarding way. You’ll write impactful code (full-stack, frontend, backend, AI integrations; it's all on the table), and make critical decisions about architecture, tooling, and product direction. There will be challenging moments, but also regular moments of genuine "wow, we built that" pride.
What you'll actually do day-to-day
Lead Development of Advanced Prompt Engineering and Retrieval Pipelines
Architect and build scalable solutions handling thousands of customer conversations daily across integrations like Zendesk, Intercom, and Salesforce. You’ll leverage cutting-edge generation pipelines to deliver rapid insights, accurate analysis, and meaningful customer interaction scoring.
Architect Real-Time Multimodal Simulations
Own the development of realistic, interactive training experiences across voice, video, and chat using platforms like OpenAI, ElevenLabs, and Vapi. Your simulations will dynamically adapt to user input, creating genuinely immersive learning environments.
Drive High-Performance User Experiences
Set the technical standard for intuitive, lightning-fast interfaces built with Next.js. You'll ensure our UIs handle complex AI interactions seamlessly, even under demanding workloads, and mentor others to achieve the same standard.
Our Team & Culture
We’re a small, focused group working full-time in our San Francisco office. We’re here five days a week because building something ambitious means collaborating closely, solving problems together, sharing ideas spontaneously, and occasionally challenging each other to padel matches, cold plunges, or karaoke evenings. We're intentional about creating a culture that's mature, supportive, and fun. You'll be joining experienced founders who've done this before, alongside a tight-knit team genuinely excited about building something impactful.
We hope you
Have at least 4 years of engineering experience, ideally at a startup (Series A to C), where you've helped ship complex, customer-facing products.
Bring strong technical leadership, including experience mentoring other engineers, leading technical decisions, or architecting significant product areas.
Have deep expertise in modern web technologies, product architecture, or AI integrations—bonus points if you’ve worked on notable or challenging projects we can explore together.
The good, the bad, and the honest truth
The highs here are incredibly high, direct collaboration with founders who’ve done this before, significant ownership, and a product you'll feel deeply proud of. The lows are that you'll need to move fast, navigate ambiguity, and sometimes tackle tough problems solo. But the reality is that startups are a bit like a sport or an instrument: you invest in it not just because you have to, but because you genuinely want to be better tomorrow than you are today.
If that sounds exciting, don’t second-guess yourself. Get in touch. Send us something you've built that you're proud of (GitHub, personal site, anything goes) and a short note about who you are and why this feels right to you. We value enthusiasm, ambition, and curiosity just as much as your technical experience.
