Lightfield • San Francisco, CA

About The Position

Lightfield is seeking a hands-on Infrastructure Tech Lead to help scale the platform through a period of rapid growth and increasing customer demand (and beyond!). After recently emerging from private beta, we’ve seen strong adoption from hundreds of businesses signing up each week, including larger, more mature teams using the product in production-critical ways.
As customer scale and data volumes grow beyond initial expectations, the infrastructure is being pushed into a new phase. This role will be central to ensuring the platform remains fast, reliable, and resilient as Lightfield expands into larger enterprise use cases.
This is not a “build a team immediately” role but instead, it’s a high-impact opportunity for an experienced infrastructure engineer to roll up their sleeves, own core scaling challenges, and help shape the long-term foundation of the system.

Requirements

• 8–12+ years of experience building and scaling infrastructure and production systems in high-growth environments
• Deep expertise in infrastructure-heavy engineering (SRE, reliability, performance, scaling) rather than data pipeline–focused roles
• Strong hands-on coding ability and comfort owning critical systems end-to-end
• Experience with Postgres performance tuning, query optimization, and scaling database-backed applications
• Strong operational instincts: monitoring, on-call practices, debugging, and systems-level problem solving
• Product-oriented mindset — motivated by customer-facing performance and real-world reliability
• Comfort operating in ambiguity at an early-stage company, where priorities evolve quickly and ownership is high

Responsibilities

• Own and improve the reliability and performance of Lightfield’s infrastructure as customer scale accelerates
• Lead efforts to reduce database latency and optimize Postgres performance for large, high-volume workloads
• Strengthen operational maturity across the stack, including observability, incident response, and production readiness
• Build scalable systems and infrastructure patterns to support larger customers and increasing usage
• Partner closely with product and engineering leadership to prioritize the most critical infrastructure work at each stage of growth
• Help define the the longer-term infrastructure roadmap, with the opportunity to influence future team shape over time

Benefits

• Competitive salary
• Meaningful early equity
• Health insurance (medical, dental, vision)
• 3 weeks of PTO
• 11 paid company holidays + we enjoy a winter holiday break
• 3 months of paid family leave
• Wednesdays work from home
• Regular team dinners, events, offsites, and retreats
• 401k plan
• Other perks include: commuter and lunch stipend
