Job description

Half craft, half stubbornness, our Performance Engineer role asks you to make JavaScript systems behave under pressure they were never promised. A hybrid Performance Engineer seat at Mount Sinai that pairs $113,000 - $164,000 with ownership, collaboration, and a long-term growth track.

Key Responsibilities

• Turn Mount Sinai's CI/CD on-call noise into alerts that actually mean something
• Troubleshoot and resolve production incidents across Adaptability-based applications
• Spot the learning-obsessed CI/CD anti-pattern in review before it spreads through Mount Sinai
• Prototype rough Laravel ideas fast, then decide which earn a place in Mount Sinai's stack
• Prototype proof-of-concept solutions for emerging technology requirements
• Translate the refreshingly-candid Laravel outage into fixes that make the next New Haven launch dull
• Ship Webpack fixes to Mount Sinai customers in New Haven, CT the same day they report them
• Lead Laravel design reviews that catch the costly mistakes before New Haven, CT builds them

What You'll Bring

• Sharp organizational skills and an ability to juggle multiple workstreams
• Strong working knowledge of PHP and CI/CD
• 6 years that taught you which corners can be cut
• A steady hand when three priorities all claim to be number one
• Storytelling instincts that turn data into a decision
