Dear Hiring Manager,
I was drawn to the Senior Backend Engineer role at Lattice because your recent engineering blog post on reducing review-cycle lag described exactly the class of problem I spent the last 18 months fixing at Zendesk — where we cut review-service P95 latency from 420ms to 180ms by moving billing off the monolith onto an event-driven architecture.
At Zendesk I led the migration of our billing service from a synchronous monolith to an event-driven microservices stack, shipped an OpenTelemetry + Grafana observability layer that six teams now depend on, and designed the idempotent retry layer for our payment webhooks — which eliminated roughly $40k per quarter in duplicate charges. I also mentored three junior engineers through the Staff-track ramp; two promoted to Senior within 18 months. What I like about those projects is that each of them cashed in technical work as a directly measurable business outcome, which is the lens I try to bring to every ticket I pick up.
Lattice is at the inflection point where backend decisions made now set the ceiling for the next three years of product velocity. The way your team writes about RFC culture, on-call, and gradual rollouts tells me it's the kind of engineering environment I'd contribute to quickly. I would particularly love to help on the billing and permissions platform, where I have the strongest track record.
I'd welcome a 20-minute call to talk about the team's current priorities and where I could land first. Thank you for reading.
Sincerely, Alex Chen
