Job Description:
About David AI David AI is the first audio data research
company. We bring an R&D approach to data–developing datasets
with the same rigor AI labs bring to models. Our mission is to
bring AI into the real world, and we believe audio is the gateway.
Speech is versatile, accessible, and human—it fits naturally into
everyday life. As audio AI advances and new use cases emerge,
high-quality training data is the bottleneck. This is where David
AI comes in. David AI was founded in 2024 by a team of former Scale
AI engineers and operators. In less than a year, we’ve brought on
most FAANG companies and AI labs as customers. We recently raised a
$50M Series B from Meritech, NVIDIA, Jack Altman (Alt Capital),
Amplify Partners, First Round Capital and other Tier 1 investors.
Our team is sharp, humble, ambitious, and tight-knit. We’re looking
for the best research, engineering, product, and operations minds
to join us on our mission to push the frontier of audio AI. About
our Engineering team At David AI, our engineers build the
pipelines, platforms, and models that transform raw audio into
high-signal data for leading AI labs and enterprises. We're a
tight-knit team of product engineers, infrastructure specialists,
and machine learning experts focused on building the world’s first
audio data research company. We move fast, own our work end-to-end,
and ship to production daily. Our team designs real-time pipelines
handling terabytes of speech data and deploys cutting-edge
generative audio models. About this role As a Senior Software
Engineer, Platform at David AI, you’ll work across product surfaces
to design clean APIs, build scalable services, and keep our systems
performant under the weight of petabytes of audio data. In this
role, you will Design, build, and maintain production-grade backend
services that power everything from data collection to
customer-facing insights. Own the architecture and performance of
distributed systems that ingest, transform, and serve audio data at
scale. Define and evolve internal APIs and service boundaries to
support a growing set of ML and product features. Build resilient,
observable, and easy-to-debug systems with strong performance
characteristics. Collaborate with product, operations, and ML teams
to rapidly iterate on new product research ideas and ship fast.
Your background looks like 3 years backend development building
scalable APIs and services. Proficient with RESTful APIs, service
interfaces, and database design (PostgreSQL, MySQL). Strong
understanding of distributed systems and service-oriented
architecture. Extensive cloud infrastructure and
infrastructure-as-code experience. Proficient in profiling,
debugging, and optimizing backend systems. Bonus points if you have
Experience launching systems from ground up in high-growth
environments (preferred). Familiarity with event-driven
architectures, async processing, or large-scale data pipelines.
Familiarity with CI/CD pipelines and DevOps best practices. Built
scalable data pipelines that have facilitated large-scale
event-driven workflows across large volumes of audio or video data.
Scaled up inference and train compute for large scale workloads in
a production setting. Some technologies we work with Next.js,
TypeScript, TailwindCSS, Node.js, tRPC, PostgreSQL, AWS,
Trigger.dev , WebRTC, FFmpeg. Benefits Unlimited PTO. Top-notch
