Job Description:
About us Encord is the universal data layer for AI that helps
300 AI teams train and run models on the right data. Our platform
indexes, curates, annotates, and evaluates data across the full AI
lifecycle, from development through production. Trusted by Woven by
Toyota, AXA, UiPath, Zipline, and more. We're an ambitious team of
100 working at the frontier of AI and have raised $60M in Series C
funding from Wellington Management, CRV, Next47 and Y Combinator.
The role We're building tools for the full Physical AI data stack —
from data acquisition, through ingestion and curation at scale, to
3D rendering, annotation, and verification. You'll solve problems
of large-scale efficient data transfer and storage, complex domain
modelling, applying the latest machine learning models, and
squeezing performance out of web browsers. You'll work with the
biggest names in robotics and autonomous vehicles, and join a
small, highly collaborative team at a crucial stage of accelerated
development. You'll be a key driver of progress on a core part of
our product, operating with a high degree of autonomy and crafting
performant, reliable, and maintainable solutions at speed. What
you'll do Build and maintain high-performance frontend experiences,
including rendering complex 3D scenes with thousands of objects at
smooth frame rates Work across the full stack — from backend data
pipelines and storage systems to frontend visualisation and
interaction Take end-to-end ownership of projects, from product and
architectural decisions through to deployment, monitoring, and
measuring user impact Work with visual, spatial, and sensor data to
make sense of the physical world Tackle complex domains at massive
scale using simple, well-crafted solutions Take initiative, be
proactive in problem-solving, and continuously seek improvements
Who we're looking for Experienced: you've seen a lot and built a
lot — personally developed and maintained multiple systems from
scratch, with a deep understanding of the trade-offs involved in
building reliable, performant software at speed At home with
challenging frontend work: you're comfortable rendering complex 3D
scenes, working with spatial and sensor data, and optimising for
browser performance Impact-driven: you want your work to have a
tangible outcome for people and aren't satisfied by products that
don't see the light of day A builder: you enjoy all aspects of
building a complete product, are comfortable moving across the
stack, and love problem-solving from first principles Comfortable
with uncertainty: happy to tackle problems without a predefined
solution, and excited to make decisions autonomously as you go A
team player: you contribute your best work and actively help others
do the same — you enjoy levelling up those around you Experience
requirements Strong full-stack engineering experience, with a
particular strength in complex, high-performance frontend work
Experience with 3D rendering, WebGL, or similar technologies for
visualising spatial/sensor data is a strong plus Proficiency in
Python and/or TypeScript; experience with React a plus Familiarity
with cloud infrastructure (GCP preferred) and containerised
deployment (Kubernetes) Experience in robotics, autonomous
vehicles, or Physical AI is a plus Tech stack We are technology
agnostic at Encord and not looking for experience across all of
these — as long as you're open to learning, please apply. Backend:
Python Frontend: TypeScript and React Deployment: Kubernetes
Infrastructure: GCP Machine learning: PyTorch, CUDA, Ray Why Encord
Competitive salary, commission, and meaningful equity in a
high-growth startup Clear, accelerated growth opportunities as the
company scales rapidly Strong in-person culture: 4–5 days/week in
our newly launched North Beach loft office Flexible PTO to fully
recharge 18 paid vacation days in the U.S. plus federal holidays
Annual learning & development budget Comprehensive health, dental,
and vision coverage Frequent travel opportunities across the U.S.,
London, and Europe Bi-annual company offsites, twice-weekly team
lunches, and monthly socials
