Senior Software Engineer, Platform

Vantage•New York, NY

About The Position

You'll join a small, high-performing platform team building the systems that power Vantage's core: data pipelines, workflow orchestration, and the infrastructure that keeps everything running reliably at scale. We move fast: 10-20 production releases a day, with a backlog that's always groomed and prioritized. We use Linear and AI tools (e.g. Claude, Codex, Cursor) as core tools, not novelties. Lightweight processes (ADRs, Slack huddles) allow us to be connected and co-ordinated without sacrificing quality. Your work will span new infrastructure, performance, scalability, and systems reliability - often in the same week. Very quickly after joining, you'll see your work reflected in how the platform performs for every customer who depends on it. We expect everyone to have a voice. If something's slowing us down or could be done better, you'll be expected to make a suggested improvement; iteration isn't just for code.

Requirements

5+ years of backend or platform engineering experience, with a track record of building systems that scale
Strong foundations in distributed systems, data pipelines, or workflow orchestration - experience with Temporal, ClickHouse, or similar tools is a plus
Comfortable contributing to infrastructure projects end-to-end: from schema design and query optimization to deployment and observability on Kubernetes
Preference for simple, durable designs - someone who knows when not to add complexity
Experience defining platform boundaries and enabling other engineering teams to build on top of reliable foundations
Someone who has led impactful projects and takes ownership seriously
A kind person
