## About the Role

Technical breadth and depth

 * Strong working knowledge across multiple stacks, including Java/J2EE, Oracle, Postgres, and modern frontend frameworks (React and Vue.js).
 * Handson cloud experience across AWS, Google Cloud Platform, and/or Azure, with ability to dive deep on architecture, performance, reliability, and operations.
 * Experience designing and operating distributed systems for B2B SaaS with a strong focus on resiliency, scalability, and cost/performance tradeoffs.

Global cloud systems + regulated environments

 * Experience with global cloud systems (multi-region, disaster recovery, high availability, data residency considerations).
 * Experience supporting FedRAMP and/or comparable government cloud certification efforts (e.g., Moderate/High) or operating within similarly regulated environments.
 * Comfort partnering with Security/Compliance while maintaining engineering velocity and strong developer experience.

Leadership as a senior IC

 * Proven ability to influence without authority-aligning stakeholders, driving decisions, and building consensus across teams.
 * Excellent written and verbal communication; able to author clear design docs and architectural proposals.
 * A coaching mindset with demonstrated impact mentoring and developing engineers across teams.

Nice to Have

 * Kubernetes and cloud-native operations experience (platform tooling, service meshes, policy-as-code).
 * Experience building internal platforms/shared services (identity/auth, developer tooling, CI/CD platforms).
 * FinOps or cloud cost optimization experience at scale.

## Description

Own platform and cloud architecture

 * Define and evolve Tango's platform architecture across AWS, Google Cloud Platform, and Azure, including networking, compute, storage, and environment strategy.

 * Drive cloud modernization initiatives (migration, re-platforming, standardization of deployment patterns, scalability and resilience improvements).

 * Create reference architectures and guardrails that enable autonomy while improving consistency and operational quality.

Establish reliability and operational excellence

 * Set reliability standards and practices (SLOs/SLIs, error budgets, capacity planning, incident response and postmortems).

 * Improve observability and operational readiness (monitoring, alerting, tracing, dashboards, runbooks) to reduce MTTR and recurring incidents.

 * Identify systemic bottlenecks (latency, throughput, resource utilization, toil) and lead cross-team initiatives to address them.

Enable government cloud readiness (FedRAMP)

 * Provide technical leadership for architectures and operational controls needed for FedRAMP / government cloud certification readiness.

 * Partner with Security/Compliance to translate controls into engineering requirements and pragmatic implementation plans.

 * Lead technical reviews for identity, access, auditability, logging, change management, and incident processes in regulated environments.

Raise the bar through standards and mentorship

 * Establish and evangelize best practices: design docs, architecture reviews, coding standards, testing strategy, CI/CD quality gates, production readiness.

 * Mentor senior engineers, tech leads, and emerging technical leaders; coach teams through complex designs and tradeoffs.

 * Create reusable patterns and "golden paths" (templates, libraries, tooling) that make the right way the easy way.
