Senior Platform Engineer, Data & Systems
$200k - $250k USD
At TriEdge Investments, we build world-class technology to drive value creation across a portfolio of 30+ companies. Our approach is staged: we start with bespoke solutions that unlock operator performance and move EBITDA; we then scale those wins through platform tools deployable across the portfolio; ultimately, we’re building an intelligent platform that redefines how private equity enables value creation at scale.
As a Senior Plaftorm Engineer, Data & Systems you’ll play a critical role in this mission - owning the design, development, and operation of the data and backend systems that power our products. You’ll architect scalable APIs, data pipelines, and distributed services that are performant in production. You’ll also design robust data models, build integrations, and ensure our systems are secure, resilient, and ready for scale. You won’t just write code: you will architect and consult on backend strategies for Mongoose and portfolio company contexts.
This is not a dev shop. You’ll act like an owner, work directly with operators and engineers, understand the “why,” and deliver pragmatic, high-quality systems that drive impact.
What You’ll Do
Become the expert on your team’s business and technical domains, including those of portfolio companies.
