Principal Software Engineer - Environments Engineering

Principal EngineerIf you are looking for a game-changing career, working for one of the world's leading financial institutions, you've come to the right place.As a Principal Engineer at JPMorganChase within the Commercial and Investment Bank Digital Channels and Connectivity team, you will own the technical strategy and delivery of the firm's next-generation test environment platform — enabling every developer across a 10,000-engineer organization to spin up an isolated, composable, production-representative virtual environment per pull request, run integration tests independently and simultaneously, and merge with confidence without contention on shared environments. You will solve the fundamental constraint that limits flow of code to production: environment bottlenecks. Your approach will be composable — reusing most unchanged components while instantiating only the services under test, with intelligent dependency resolution, traffic isolation, and automatic teardown.

You will design and build the MVP hands-on, then shift to hardening, socializing, and driving adoption at scale across multiple organizations. You will partner as a peer to engineering delivery leadership and collaborate closely with performance engineering, SRE, and quality engineering to ensure the platform meets the demands of a large, hybrid (cloud and on-premises) service estate.Job responsibilitiesArchitect the composable virtual environment platform — enabling per-PR, per-developer isolated test sessions that reuse unchanged shared services and instantiate only the services under test/change, with correct dependency resolution across the service graphDesign the traffic routing and isolation layer that directs requests to the correct version of each service within a virtual environment session, leveraging header-based routing, service mesh capabilities, and service discovery without cross-session contaminationBuild the dependency graph intelligence that determines which services must be instantiated live vs. reused from baseline vs.

virtualized/stubbed for a given test scenario — making composable environments feasible at 1,000+ service scaleDeliver a self-service developer experience through CLI, API, and developer portal integration that enables teams to declare environment needs, provision in minutes, execute integration tests, and exit — with zero dependency on a shared environment or manual coordinationDefine and implement data strategies for composable environments, including synthetic data generation, production data masking, snapshot/restore workflows, schema versioning, and repeatable dataset management across heterogeneous data stores (Oracle, Kafka, Cassandra, MongoDB, CockroachDB, DynamoDB, PostgreSQL)Implement lifecycle management, cost governance, and resource reclamation — including time-to-live policies, idle detection, automatic teardown, quota management, chargeback attribution, and FinOps reporting across cloud and on-premises infrastructureIntegrate the platform into CI/CD pipelines as a native stage — environments created on PR open, tests executed, results reported, environments destroyed on merge/close — with support for Jenkins, Spinnaker, GitHub Actions, and Argo CDEnsure the platform operates reliably across hybrid infrastructure (Kubernetes on-premises and EKS, VMs, and managed cloud services) with consistent provisioning semantics, cross-network connectivity, and acceptable spin-up latency regardless of hosting tierEstablish platform reliability SLOs, observability, and operational runbooks — measuring time-to-environment, environment success rate, isolation correctness, and developer satisfaction as first-class product metricsArchitects 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 teamsApplies 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 scaleRequired qualifications, capabilities and skills15+ years of professional software engineering experience, with significant experience building internal developer platforms, environment-as-a-service systems, or large-scale infrastructure orchestration consumed by thousands of engineersDemonstrated experience designing composable or virtual environment architectures — including service graph decomposition, selective instantiation, dependency stubbing/virtualization, and traffic isolation patterns that avoid full-clone approachesDeep expertise in traffic routing for environment isolation — header-based routing, service mesh traffic control (Istio, Linkerd, or equivalent), service discovery, and strategies that prevent cross-environment contamination at high concurrencyProduction experience operating Kubernetes across on-premises and cloud environments (EKS), with strong understanding of namespace isolation, resource scheduling, multi-tenancy, and operational tradeoffs across hybrid infrastructureHands-on proficiency in Go, Rust, or Java for building production-grade platform services, combined with strong infrastructure-as-code experience (Terraform, Ansible) for provisioning and configuration management with change control and repeatabilityProven ability to provision and manage stateful test infrastructure in an automated fashion across heterogeneous data stores — relational databases (Oracle, PostgreSQL), document stores (MongoDB, CockroachDB), message brokers (Kafka), and cloud-native services (DynamoDB)Experience with CI/CD pipeline design and extension — integrating environment lifecycle as a pipeline-native capability across Jenkins, Spinnaker, GitHub Actions, or Argo CDStrong platform-as-a-product thinking — designing clean APIs, contracts, composability, multi-tenancy, scheduling, cost modeling, and measuring platform success through adoption metrics and developer experience outcomes (DORA, time-to-environment, satisfaction)Demonstrated ability to drive platform adoption at scale (1,000+ engineers) through advocacy, enablement, excellent self-service UX, and partnership with engineering leadership — not just building but ensuring the organization actually uses itDemonstrated 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 dataStrong 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 reusePreferred qualifications, capabilities and skillsNamespace-per-PR / lightweight isolation (no full env cloning); GitOps environment-as-code alongside app codeScalable test data: masked prod snapshots, on-demand restores, synthetic data, repeatable dataset management across platformsDeveloper portal integration (Backstage or equivalent) for self-service, catalog visibility, and env health dashboardsAI/ML for infra optimization: predictive scaling, change-set–driven env composition, automated dependency graph resolutionEvaluate/integrate open source for enterprise use: supportability, security, supply-chain integrity, long-term viabilityHybrid connectivity expertise: on-prem ? cloud routing, VPN/private link topologies, latency considerations for ephemeral envsFinancial-services regulated operations: compliance, data sensitivity controls, auditability as hard constraintsThis position is subject to Section 19 of the Federal Deposit Insurance Act.
