DevOps
Requirements
  • 8+ years of professional software-engineering experience
  • 3+ years leading critical projects or teams
  • Deep, hands-on expertise scaling and operating PostgreSQL—designing partitioned/sharded schemas, tuning indexes and queries, automating backups and observability, and running resilient multi-TB clusters with replication and failover
  • Proven track record of shipping high-impact, production-grade systems at scale
  • Desire to work in a fast-paced environment, continuously grow, and master your craft
  • Collaborative, low-ego attitude with a history of mentoring engineers and leveling up the people around you
Responsibilities
  • Scale Unify: Ensure that Unify can scale to support our hyper growth and provide a stable platform for large scale customers such as Cursor, Perplexity and Decagon
  • Drive the technical roadmap: Collaborate with Product, Design, and GTM stakeholders to translate ambiguous business goals into a clear, phased engineering plan.
  • Set the bar for engineering excellence: Establish coding standards, CI/CD pipelines, testing strategy, reliability targets, and observability practices that future teams will inherit.
  • Evaluate & integrate new tech: Rapidly prototype with third-party APIs, databases, model-serving platforms, and infra vendors to accelerate customer value.
  • Mentor & lead: Provide technical leadership for (and — if you’re up for it — manage) engineers across domains—pairing, reviewing, and unblocking as you go.
Desired Qualifications
  • Experience leading large-scale PostgreSQL deployments
  • Experience with model-serving platforms and infrastructure vendors
  • Experience designing and implementing scalable backend architectures with a focus on reliability and observability
  • Experience partnering with cross-functional teams (Product, Design, GTM) to ship features
