Staff Software Engineer (L4)

Twilio Segment is the customer data platform half of Twilio, and this Staff Engineer (L4) seat is on the team that runs its data pipelines. These are the systems that ingest and route several hundred thousand events per second and query petabytes, so the job is high scale distributed systems work: designing for high availability and throughput, accepting eventual consistency where it buys reliability, and keeping the whole thing cost efficient under real load. As a Staff engineer you set technical direction, act as a tech lead when needed, and mentor other engineers on architecture and design. It is fully remote within India. This is a senior, hands on role for someone who has already built and operated large scale data infrastructure and wants ownership of a core, high traffic platform rather than a greenfield toy.

What the posting asks for:
- 8+ years writing production grade code, with real experience building and operating high scale distributed systems (several thousand events per second and processing engines handling 1M+ events per second).
- A Bachelor's or Master's in Computer Science, Engineering or a related field.
- Depth in designing for high availability, throughput and eventual consistency, plus reliability and security of the platform.
- The ability to act as a team tech lead and mentor other engineers on architecture.

The day to day: you design and ship high scale routing for the Segment data pipelines, build and optimise globally available distributed systems, partner with product and other Segment teams, and support platform reliability and security.

Location: fully remote within India.

Honest read: a genuine Staff level distributed systems role. Twilio notes it welcomes non traditional paths, but the 8+ year bar and the 1M events per second scale are real. Best for engineers who have operated data platforms at scale and want a remote seat with technical leadership.
