Dear Hiring Manager,
I'm applying for the Principal Software Engineer role on the Sales Cloud Platform team. Your team's recent Dreamforce session on the multi-tenant query router rewrite — specifically the decision to keep per-org isolation inside a shared cluster rather than splitting into dedicated tenants — is the same trade-off I've been making at HubSpot for the last three years on our enterprise tier, and I'd like to bring that work to the canonical platform.
At HubSpot I led the multi-tenant performance rewrite for our Enterprise and Pro tiers, serving 8,400 enterprise accounts on a shared platform processing 1.1B API calls per day. The original per-org isolation model relied on query hints and was leaking latency across tenants during peak sync windows; I designed a tenant-aware query planner, worked with our security team to keep the SOC 2 Type II audit trail intact throughout the migration, and rolled it out account-by-account starting with our 12 largest customers so they'd get the benefit first and flag regressions fastest. Results: p99 query latency dropped from 2.1s to 340ms, cross-tenant leakage incidents went from 3 per quarter to zero over 12 months, and the NPS of our top enterprise CSM team (who felt it first) went from 34 to 61. Equally important to me: two of the engineers on that rewrite were junior hires from our Boston apprenticeship program for career-changers, and both were promoted to senior within the year — which is the kind of thing I want to keep doing wherever I work next.
Before HubSpot I was IC4→IC5 at a Series C CRM startup (Copper, Google-workspace-native) where I owned the integration framework and shipped the first OAuth-based partner SDK. I've also earned Salesforce Administrator and Platform Developer I via Trailhead (superbadges in Apex Specialist and Lightning Web Components Specialist) — partly because my team integrates with Salesforce, and partly because I find the Trailblazer learning format unusually well-designed. That mix — enterprise platform experience, genuine ecosystem time, and a track record of developing other people — is what I'd bring to Sales Cloud Platform.
I'd welcome a conversation about the team's current priorities on Trust-layer performance and the roadmap for Einstein integration inside the query planner. I can share a design doc from the HubSpot rewrite (internal-scrubbed, 9 pages) and my Trailhead Trailblazer profile if it's useful for the loop.
Sincerely,
[Your Name]
