Senior Platform Engineer

Jellyfish is rewriting the manual on how high-performing engineering teams actually work. We don't just provide data; we provide the blueprint for effective communication and development.
We are looking for a Senior Platform Engineer who views "manual effort" as a bug. You aren't here to just watch dashboards - you’re here to build the pavement as the jet is taking off. We’re scaling fast, dealing with massive data sets, and we need someone who is obsessed with performance, resilience, and the art of reducing toil.

What you’ll actually be doing:

• Engineering the Platform: You’ll work hand-in-hand with product teams to lay the infrastructural groundwork for new apps. If it’s repetitive, you’ll automate it. If it’s fragile, you’ll harden it.

• Killing Toil: You’ll identify the "friction points" in our dev lifecycle and build the Terraform modules or Python tooling to make them disappear.

• Architectural Advocacy: You aren't a gatekeeper; you’re an enabler. You’ll champion sound software design and "paved road" patterns that allow devs to move fast without breaking things.

• Observability over Monitoring: Moving us beyond simple alerts to deep introspection. You’ll help us use tools like Honeycomb and Grafana to understand why things happen, not just that they happened.

• High-Agency Incident Response: You’ll help us evolve our incident remediation from "fixing the fire" to "learning from the heat," driving a culture of blameless retrospectives and systemic improvements.

You’re a great fit if:

• Python & Linux are your native tongues. You’re comfortable writing clean, testable code to manage infrastructure.

• Terraform is your go-to for "Source of Truth." You have strong opinions on how to structure state and modules at scale.

• You hate doing the same thing twice. You’d rather spend four hours automating a task than ten minutes doing it manually every week.

• You’re a "Trailblazer." You enjoy being the first one to dive into a new AWS service or observability tool to figure out how it fits our stack.

• You lead by influence. You prefer building consensus and "teaching others to fish" over rigid process controls.

• You balance the "How" with the "Why." You understand that a perfect technical solution is only perfect if it solves a real business need.

Bonus Points:

• You’ve survived (and thrived in) a rapidly scaling startup.

• You have strong opinions on the future of developer experience (DevEx).

• You’ve managed complex data environments (like Databricks or massive RDS clusters) and lived to tell the tale.

A list of job experiences and qualification requirements is great, but humility, a performance-driven attitude, and a team-player approach are most important to us. We love to have fun and win in the process. We only hire people who have a passion for building great companies in an environment where a sense of humor is a must.

Occasional travel may be required.

Applicants must be authorized to work for any employer in the US. We are unable to sponsor or take over sponsorship of an employment visa at this time.
