This is a hands-on leadership role for an engineer who sets direction rather than waits for it. You will tackle the performance problems that others cannot, work across the full stack from the browser to the back end and down to the operating system, and define how performance is engineered, measured, and sustained at scale. You will set standards, mentor strong engineers, and build the tools and practices that make high performance a default rather than an afterthought. Just as importantly, you will shape the strategy, build the roadmap, and earn the support of senior stakeholders to see it through. If you want real ownership, deep technical challenges, and the chance to raise the bar for an entire organization, this is the role for you.\nJob responsibilities\nOwn the hardest cross-stack performance problems-from the browser through the back end down to the operating system-and establish the troubleshooting standards and playbooks others follow\nDefine and institutionalize NFRs and SLOs (p95/p99 latency, throughput, ramp profiles, error budgets) and serve as the final technical authority for performance sign-offs across platform releases\nDrive proactive performance engineering through early bottleneck detection, architectural guidance, capacity modeling, and runtime tuning\nBuild the tooling and infrastructure that turns performance testing into a scalable, self-service capability across teams\nDesign and maintain automated performance test suites (load, stress, soak, spike, capacity) with environment-aware, fully automated execution\nEmbed performance gates into CI/CD pipelines and build dashboards that correlate test signals with production telemetry against defined SLOs\nArchitects and governs agentic AI-enabled engineering workflows (using enterprise-authorized tools within the work environment) to improve delivery speed, code quality, and operational outcomes at scale (e.g., AI-driven PR review assistance, test generation/maintenance, release readiness checks, incident triage and root-cause acceleration), while defining guardrails for validation, security, resiliency, and reuse across teams\nApplies knowledge of tools within the Software Development Life Cycle toolchain, including enterprise-authorized AI-assisted development and automation capabilities, to improve the value realized by automation at scale\nRequired qualifications, capabilities, and skills\nExtensive performance engineering experience (typically 12+ years) for high-traffic distributed systems-web, APIs, microservices, event-driven, and data-centric-built on a strong broader software engineering foundation\nDeep hands-on expertise debugging performance problems in distributed systems, with the ability to go as deep as the system call boundary; strong knowledge of JVM internals \nFluency in both the Java (back-end) and Node.js/React (front-end) ecosystems, including front-end and browser-stack performance debugging best practices\nHands-on software engineering experience with Java/Spring Boot and Kubernetes (self-managed and EKS)\nStrong systems and cloud performance depth, including Linux performance tooling, JVM tuning, containers, and OS-level troubleshooting under load\nDeep expertise in workload modeling, queuing theory, and statistical analysis of latency and throughput; fluent with percentile-based SLOs and error budgets\nExpert with at least one industry-standard load and protocol testing tool (e.g., JMeter, BlazeMeter, k6), with scripting and orchestration skills in Java, Python, or TypeScript for performance automation\nStrong observability and APM capabilities using tools such as Dynatrace and/or OpenTelemetry, plus RUM and synthetic monitoring, with dashboarding in Kibana and/or Grafana\nProven ability to influence senior technical leaders, communicate complex performance trade-offs clearly, set engineering standards, and build tooling and practices that make high performance a scalable, self-service capability across teams\nDemonstrated experience designing and leading adoption of agentic AI-enabled development practices (using enterprise-authorized tools within the work environment) across teams, including setting standards for human-in-the-loop validation, auditability/traceability of changes, and secure handling of sensitive data\nStrong understanding of responsible AI use and control expectations in engineering workflows, including security/resiliency implications, data sensitivity, and risk-based governance; ability to influence senior technical leaders on safe scaling patterns and reuse\nPreferred qualifications, capabilities, and skills\nExperience operating in financial-services scale, low-latency systems, and/or regulated environments\nExperience with data-platform performance optimization (e.g., Oracle tuning, JDBC pool tuning, Kafka throughput/partitioning, caching strategies)\nExperience with service virtualization and fault injection tools (e.g., WireMock, Mountebank, Toxiproxy), including record-replay and dynamic templating\nFamiliarity with modern cloud-native load testing frameworks such as k6\nFamiliarity with service mesh technologies (Istio/Linkerd) and traffic-control patterns (rate limiting, backpressure)\nKnowledge of advanced performance tooling (e.g., perf, eBPF) and production-grade troubleshooting practices\nPractical application of LLMs for test generation, anomaly detection, or automated reporting in engineering workflows\nThis position is subject to Section 19 of the Federal Deposit Insurance Act. As such, an employment offer for this position is contingent on JPMorgan Chase’s review of criminal conviction history, including pretrial diversions or program entries.","description_format":"text","description_chars":6076,"description_truncated":false,"requirements":{"experience_years_min":12,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Forest Resources","Asset Management & Funds","Land & Agriculture Property"],"lifecycle":[{"event":"open","at":"2026-10-23T10:07:03Z"}],"visa":[],"liveness":{"score":33,"band":"fade","label":"Fading","p_open":1,"p_active":0.741,"p_room":0.45,"age_days":7,"expected_fill_days":5,"reasons":["conf:0","velocity","win:tail","comp:brand"],"computed_at":"2026-10-28T05:59:10Z"},"pay":null,"html_url":"https://alion.io/job/campbell-global-principal-software-engineer-performance-engineering","json_url":"https://alion.io/job/campbell-global-principal-software-engineer-performance-engineering.json","meta":{"generated_at":"2026-10-29T02:46:41Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":4188,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":2649833},"rest":"https://alion.io/mcp/rest/get_company?id=2649833"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcampbell-global-principal-software-engineer-performance-engineering"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fcampbell-global-principal-software-engineer-performance-engineering"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fcampbell-global-principal-software-engineer-performance-engineering"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/campbell-global-principal-software-engineer-performance-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcampbell-global-principal-software-engineer-performance-engineering"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3145691}},{"tool":"search_jobs","arguments":{"company":"campbellglobal.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3145691},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
