Own the design and delivery of systems within the Growth domain, from architecture through production operation.
Decompose large, ambiguous projects into workstreams the team can run in parallel — and find the genuinely hard part early rather than discovering it in month three.
Write design docs and architecture decision records that outlive the project and anticipate the next few years of change.
Set the bar for the codebase: refactor toward clarity as a habit, and introduce abstractions that others adopt because they help.
Design the testing strategy for your systems and improve CI reliability, so the team can ship confidently.
Lead incident investigation, and produce blameless postmortems whose action items measurably reduce recurrence.
Mentor engineers deliberately, and use code review as a coaching surface rather than only a defect filter.
Act as a genuine peer to Product and Design — propose cheaper solutions to the real user problem, and push back on scope with data.
Translate technical risk into business consequences for stakeholders, and deliver bad news early with options attached.
