Note: The job is a remote job and is open to candidates in USA. Juniper Square is a technology company focused on transforming private markets through innovative solutions. They are seeking a Senior Staff Software Engineer to lead the architecture and evolution of their core systems, ensuring scalability and performance for large private equity institutions. The role involves hands-on engineering, technical leadership, and collaboration with various teams to align technology strategy with business objectives.
Responsibilities
- Define and own the end-to-end systems architecture strategy across services, infrastructure, and developer platform
- Designing frameworks and design patterns that accelerate the work of the rest of engineering org
- Design scalable, fault-tolerant distributed systems spanning synchronous APIs, asynchronous workflows, and event-driven architectures
- Establish standards for service design, API contracts, multi-tenancy, and inter-service communication
- Lead architecture reviews and technical decision-making for high-stakes, cross-cutting initiatives
- Drive adoption of modern architectures (event-driven systems, platform engineering, infrastructure as code)
- Design and prototype critical platform and infrastructure components
- Write production-quality code for complex or high-impact areas
- Review service designs, infrastructure changes, and performance-critical code paths
- Troubleshoot performance, scalability, and reliability issues across services, queues, caches, and databases
- Optimize workloads for latency, throughput, concurrency, and cost
- Design and architect a scalable cloud platform supporting compute, networking, storage, service orchestration, and deployment across all product lines
- Build a paved-road developer platform — golden paths, internal tooling, CI/CD, and self-service infrastructure — that makes the right way the easy way
- Create reusable platform primitives and internal APIs that product teams can compose rather than rebuild
- Enable self-service infrastructure for engineering teams through standardized patterns, templates, and platform capabilities
- Partner with AI workflow teams, product, and security teams to support production AI workloads, from inference pipelines to agent fleets
- Design systems for safe agentic execution, including isolation boundaries, resource governance, auditability, and human-in-the-loop controls
- Ensure reliability, scalability, and resilience of the platform, including high availability, monitoring, and disaster recovery readiness
- Architect core systems to handle the data volumes and structural complexity of $100B+ AUM managers: thousands of entities, tens of thousands of LPs, and deep multi-tier fund structures
- Define scalability targets and re-architect bottlenecked systems ahead of demand, ensuring performance holds at 10x current transaction and data volumes
- Design enterprise integration surfaces — APIs, bulk data interfaces, and ERP/GL connectivity — that fit into the existing technology estates of large institutional GPs
- Meet the security, compliance, and operational diligence expectations of the largest PE firms, such as, SSO/SCIM, granular entitlements, audit trails, and data residency
- Serve as the senior technical voice in enterprise sales and onboarding conversations where architecture, scale, and resiliency are decision criteria
- Lead incident response maturity: on-call practices, blameless postmortems, and systemic remediation
- Drive capacity planning, load testing, and chaos/resilience engineering practices
- Optimize cloud spend through architecture, workload placement, and continuous cost engineering
- Mentor senior engineers across platform, infrastructure, and product teams
- Partner with product, data, and business teams to align systems investments with company outcomes — including the GPX upmarket expansion
- Translate business and product requirements into scalable, operable system designs
- Influence roadmaps using platform, reliability, and cost considerations
- Act as the executive technical authority for systems architecture and production engineering
- Evangelize AI adoption, including AI-assisted engineering and operations
- Help promote a culture of operational excellence and outcome-driven innovation
- Become a role model for engineering excellence for the rest of the org
