Senior Software Engineer - AI Infrastructure at Cornerstone Research in US

Job description

• This role is open to candidates in Boston, New York, Washington, D.C., Chicago, LA, Silicon Valley and San Francisco.
• The Cornerstone Research Data Science Center is seeking a Senior Software Engineer to design, build, harden, and scale infrastructure that powers AI applications across the firm. This is a hands-on role within a versatile software engineering team that operates with a high degree of autonomy and scope.
• You will co-own the platform layer beneath the firm’s AI tooling, including inference gateways, containerized environments, and observability tools. The work is a mix of building new capabilities and hardening existing infrastructure in a domain where confidentiality, isolation, and reliability are critical.
• This role is ideal for an engineer who enjoys building products and services for other developers: someone equally comfortable standing up a new service, tracing a request across the platform to determine why it was slow, figuring out why a container works locally and fails on the host, and replacing a manual deployment step with a pipeline. You will work closely with engineers who own the platform layer and developers who build on it.

Responsibilities

• Platform Ownership: Design, build, and operate the systems and shared infrastructure that AI applications at the firm depend on.
• Observability & Reliability: Own metrics, logs, and traces for the platform. Instrument services, build dashboards and alerts, and use telemetry to diagnose and resolve performance and reliability issues.
• Hardening & Operations: Improve the resilience, security posture, and operational maturity of existing systems.
• Developer Enablement: Provide the tooling, environments, and deployment paths that let application developers ship AI agents and workflows onto the platform quickly and safely. Treat internal developers as your users.
• Collaboration: Partner with engineers, data scientists, product managers, and corporate departments (Security, IT) to understand requirements, communicate tradeoffs, and deliver platform capabilities that fit how the firm works.

Requirements

• Required
• Experience: B A/BS with 4+ years of professional software, platform, infrastructure, or DevOps engineering experience, OR a Master or PhD in a quantitative field (e.g., Computer Science, Math, Economics) with 2+ years of industry experience.
• Engineering Mindset: Strong fundamentals in system design, with the ability to build reliable systems that handle sensitive data with high reliability.
• Technical Versatility: Demonstrated ability to work across tech stacks and pick up new languages or frameworks quickly
• AI-Native Development: Experience using AI-powered coding assistants to accelerate development; strong interest in staying at the forefront of AI-enabled engineering.
• Agentic Tooling: Familiarity with building AI agents (e.g., using the Claude Agent SDK), and with what it takes to run agents safely in sandboxed environments.
• Containers: Deep, practical experience with environment isolation concepts and container solutions such as Docker, Podman, or Bubblewrap
• Observability: Hands-on experience with metrics, logging, and distributed tracing, ideally with the Grafana ecosystem (Grafana, Loki, Tempo, Mimir, Alloy) and OpenTelemetry.
• Communication: Ability to clearly articulate technical tradeoffs, document systems well, and explain progress to both technical peers and non-technical stakeholders.
• Reverse Proxies & Gateways: Experience configuring and operating reverse proxies or API gateways (e.g., Nginx): routing, TLS, authentication, rate limiting, and request/response handling.
• Networking & Service Connectivity : Solid grasp of how services find and talk to each other across hosts and networks, including HTTP, gRPC, and similar protocols, TCP and TLS, DNS and service discovery, ports and subnets.
• CI/CD & Infrastructure as Code : Experience with GitLab CI or similar pipelines, and with infrastructure-as-code or configuration management tools (e.g., Terraform, Ansible).
• Orchestration : Exposure to Kubernetes or similar orchestration systems, and an informed view on when they are and are not the right tool.
• Hybrid Environments : Experience operating across on-premises and cloud infrastructure.
• Identity & Secrets : Familiarity with SSO/OIDC, identity and access management, secrets management, and audit logging.
• Regulated or Professional Services Environments: Experience building infrastructure within professional services, legal, financial, or highly regulated industries.
