About the job

Responsibilities

Develop and drive scope in one or more areas of the infrastructure stack. Take ambiguous problems from framing through design, implementation, and operation.
Set the technical direction for your areas — write RFCs, evaluate tradeoffs, and make decisions that affect how the team operates for years.
Act as the final escalation point on-call. Drive resolution of the hardest incidents and lead post-incident reviews that produce durable fixes.
Raise the bar through design review, code review, and mentorship. Develop other engineers by working alongside them.
Partner with security, compliance, product engineering, and ground station ops as a peer technical leader. Translate between infrastructure constraints and the needs of other teams.
Identify systemic toil and underinvestment. Propose and execute the work that eliminates it, including work that spans other engineers' domains.
Represent the infrastructure team in technical decisions across the organization. Write the documents others reference.
