Voice AI Engineer

Who?

We are Sei, an agentic AI platform for financial services. Since launching, we're live with large enterprises across the US, Europe, and APAC and growing at double digits per month.

We are backed by world-class investors, including Y Combinator, Tribe Capital, PayPal, Picus Capital, & Hashed. Pranay (CEO) and Ram (CTO) are the founders. We have a combined 20+ years of experience building fintech and tech products for businesses & customers worldwide at companies such as Deutsche Bank, Cloud Kitchens, PayPal, TransferWise, and Amazon, among others.

We are looking for a voice AI engineer to help shape the company's tech, product, and culture. We are currently working with a bunch of enterprise customers and banks, and are experiencing rapid growth. We are looking to hire mid to senior engineers who can take our V1 into a more scaleable, robust platform as we prepare for more growth.

What to expect

You Can Expect To Do All Of The Following

• Build large-scale agents for voice and chats for enterprises
• Evaluate multiple models for VAD, turn detection, interrupt handling, etc.
• Handle MLOps to ensure low-latency responses
• Clean, prune, and collect datasets to analyze model performance, hallucination rates, recall, etc.
• Research and implement SOTA approaches for knowledge graphs and Graph RAGs
• Run evals

Our values

• Continuous 360 feedback: Everyone is expected to share constructive, critical feedback with everyone else, including the founders.
• Product-minded: Everyone shares product ownership, so we expect everyone to engage in customer outreach, support, and customer conversations to gather feedback and identify new features.
• Doers over talkers: We spend time figuring out the right direction, then execute quickly. No one is too "senior" to do a job - the CTO will code every day, the CEO will sell every day, and everyone takes care of customer support on a schedule. We understand the difference between real work and pretense.
• Humanity over everything else: We sell the product to businesses, but in reality, we sell it to real humans on the other side. Our end customers are consumers using the product through our UI or integrated with our APIs, so we are building the world's most human-centric company (no pun intended). Kindness is expected, and empathy is the core value we're looking for.

About You

• We expect you to have built things from 0 to 1 or 1 to 10 (which is typically an early or growth stage startup)
• Experience with voice AI is mandatory. You should have built and taken voice AI agents to production, run monitoring, and made improvements. You should have worked with frameworks such as Pipecat and Livekit.
• We expect you to have an extremely strong bias toward action, strong motivation, side projects, and to have built and/or scaled systems from scratch.

Pay and benefits: We offer a solid, competitive package (including early-stage equity). We give you the flexibility to choose the split between cash and equity.

Why you should not join

• If you want to coast along and do the minimal possible work. The work hours will be intense - we believe in less micro-management and high accountability. It takes a lot of sweat to get a startup off the ground, and you will let the team down if you don't pull your socks up.
• If you cannot do intense work every day (with exceptions, of course). The above point talks about the sheer quantity of the work, but this one is more about the quality. We have intentionally kept meetings to a bare minimum, so people can get into their zones and be productive. But if this distracts you and you end up doing half-assed work, then we might not be the right fit for you.
• If you have low ambition. We believe in hiring ambitious and hard-working folks who will never take no for an answer. We also hire people with strong intrinsic motivation. People who have succeeded so far are the ones who can run with things even without structure and work hard even when no one is watching. People we have had to let go have had issues with motivation, needed babysitting, do fake work to get standup updates out, and cannot handle feedback.
• If you are not easy-going with the team. We have hired a team of people who are friendly and help each other out. There is zero attitude in the team. We sometimes have conflicting opinions on how things should be done, but at the end of the day we disagree and still commit to doing what moves the company forward.
• If you cannot be with us in our Gurgaon office (Sector 54, Golf Course Rd) or Chennai office (T.Nagar) at least 4 days a week.
