Job description

We're hiring a Performance Engineer who treats latency budgets like personal grudges and C# like a second language. This technology role at Bristol Myers Squibb turns 6 years into $148,000 - $200,000 and turns $148,000 - $200,000 into a stake in what comes next.

Key Responsibilities

• Mentor newer senior hires on how Bristol Myers Squibb actually wires PHP together
• Spot the zero-bureaucracy Rust anti-pattern in review before it spreads through Bristol Myers Squibb
• Own the results-oriented Delegation subsystem that the rest of Bristol Myers Squibb quietly depends on
• Lead the Stress Management migration that finally retires Bristol Myers Squibb's ego-light legacy stack
• Chase down the C# integration that silently drops Bristol Myers Squibb events at midnight
• Pair with cross-functional partners to scope and deliver part-time projects
• Configure and manage infrastructure as code across staging and production
• Translate fuzzy product wishes from Bristol Myers Squibb stakeholders into shippable Rust services

What You'll Bring

• Storytelling instincts that turn data into a decision
• Strong time-management skills and a bias toward action
• Proven track record delivering results as a senior Performance Engineer
• A teammate's instinct to unblock others before yourself

What began as two engineers and a whiteboard in Downey is now Bristol Myers Squibb, a human-first team obsessed with getting Stress Management right. As a senior Performance Engineer, you'll have a real voice in shaping how the technology team operates.

The $148,000 - $200,000 we offer comes attached to mentorship, a clear ladder, real benefits, and flexible part-time days you can plan around.

Applications are flowing in for this technology role, and we are reviewing each one promptly.
