About
The agents that drive browsers are the part of Vaxnori AI that touches the outside world. You’d make them reliable: isolated sessions, safe retries and runs we can replay step by step.
What you’d do
Build and harden the browser automation runtime that agents use for forms and portals.
Design retry and replay so a failed run can be resumed or audited without side effects.
Instrument runs so drift in a vendor’s page is caught before it causes a wrong filing.
What we’re looking for
Several years building production systems, ideally with browser automation or distributed jobs.
You care about idempotency and can explain the failure modes you designed against.
Comfortable reading other people’s HTML and turning messy pages into dependable steps.
NICE TO HAVE
You've worked on scraping, testing or RPA tooling at scale, or you've debugged a flaky end-to-end suite until it stopped being flaky.
Your first 90 days
Weeks 1-2
Read the replay logs for the last month of failed runs and pair on two live fixes.
Weeks 3-6
Ship per-task session isolation for the three most-used filing portals.
Weeks 7-12
Own drift detection and the retry policy, with on-call shared across the agents team.
COMPENSATION
$180k-230k
Plus 0.25-0.5% equity, four-year vest. Band is fixed by level, not negotiation.
