Applied Talent Solutions

Founding Senior Software Engineer

Company: Applied Talent Solutions

Location: San Francisco, CA

Posted on: July 10

Help build the platform that finally makes email truly collaborative for enterprise teams. Join as a hands-on founding engineer, shape the architecture from day one, and earn top-tier compensation plus meaningful early-stage equity.


  • Early-stage, high-velocity start up experience is mandatory for this role.
  • Relocation assistance and U.S. visa sponsorship are available for the right candidate.


The Mission

Despite decades of innovation, email remains the de-facto workflow hub inside large organisations - but it was never designed for real-time, multi-person collaboration. Were creating a unified backend that turns every thread into a living workspace, integrates seamlessly with internal systems, and scales from secure on-prem deployments to the public cloud. Your work will redefine how Fortune 500 teams communicate and execute.


What Youll Do

  • Design & build the core distributed services, APIs and data pipelines that power a high-volume, low-latency collaboration layer
  • Own architecture decisions across Python and TypeScript-based micro-services, driving code quality, testing and deployment strategy
  • Conquer deployment challenges for enterprise customers (on-prem, hybrid, SaaS) with a strong focus on security and reliability
  • Partner directly with design-partners (leading global enterprises) to iterate from zero-to-one and scale to GA launch
  • Lay the technical culture for a new company - mentoring engineers, defining best practices and paving a path toward staff/principal roles


What Were Looking For

  • 10 + years of professional software engineering with deep backend infrastructure / distributed-systems expertise
  • Proven success shipping B2B SaaS products to enterprise or F500 users; start up or growth-stage VC-backed experience strongly preferred
  • Fluency in Python (services, data processing) and TypeScript (service or platform work); comfortable picking up new tech as needed
  • Experience designing scalable APIs, messaging systems, or real-time collaboration backends
  • Hands-on, IC-first mentality but capable of guiding ~10 engineers as the team scales
  • CS degree (or equivalent strong fundamentals); familiarity with modern AI/LLM concepts is a plus


Why Youll Love It Here

  • Founding-level ownership with room to grow into senior leadership as the company scales
  • Top-tier compensation plus generous early-stage equity
  • Work alongside a small team of serial entrepreneurs and alumni from the worlds most successful infrastructure companies - access to unmatched advisors and design partners (kept confidential until later stages)
  • Brand-new San Francisco office; five days on-site for rapid iteration (relocation & visa sponsorship fully supported)
  • Green-field codebase, modern stack, fast shipping velocity, and the resources of a leading deep-tech investor behind you
