Do you love working on challenges that no one has solved yet? Imagine what you
could do here. At Signal Labs, new ideas have a way of becoming extraordinary
products, services, and customer experiences very quickly. Bring passion and
dedication to your job and there's no telling what you could accomplish! Join our
team, we work in a startup environment and you will be part of every stage of
development working multi-functionally with business, development engineers,
and operations from the concept phase to deployment.
At SignalLabs, we are passionate about enabling enterprises to turn their data into
decisions that move the world forward, from helping financial institutions detect
risk in real time to accelerating how healthcare and industrial teams act on critical
signals. We do this by building and running SignalOS and SignalGraph, the
platform behind the world's most demanding signal intelligence workloads, so our
customers can convert raw events into context, context into hypothesis and
reasoning, and hypothesis into Attention. Founded by engineers and customer
obsessed we leap at every opportunity to solve hard technical challenges, from
exploring connected data to scaling our infrastructure across billions of signals a
day. And we're only getting started.
The impact you'll have:
As a software engineer with a backend focus, you will work with your team to
build infrastructure and products for the SignalLabs.ai platform at scale. Our
backend teams span the architectural pillars that power signal intelligence end-to-
end: Data Discovery, where we crawl, profile, and onboard heterogeneous data
sources into the platform; the Semantic Module, where raw entities and events are
resolved into a unified, meaning-rich representation; the Signal Detection and
Correlation Engine, where signals are scored, joined, and elevated into high-
confidence signals across time and context; the System of Attention, where the
most consequential signals are routed, ranked, and surfaced to the right decision-Job Description: Senior Staff Engineer1
maker at the right moment; and the Reinforcement Learning Feedback Loop,
where every human and machine response is captured to continuously sharpen
detection, correlation, and prioritization. You'll own meaningful surface area in one
of these domains while shaping how they compose into a single, coherent
platform.
