Senior Infrastructure Engineer

About the Role

As a Senior Infrastructure Engineer at Fieldguide, you'll own critical infrastructure decisions, build platforms that other teams rely on, and bring a level of rigor and reliability that makes the whole organization move with more confidence. In a product built around trust and compliance, the quality of our infrastructure isn't just an engineering concern, but also core to what we promise our customers.

Our engineering hub is located in San Francisco. This role is open to remote candidates anywhere in the US; Bay Area-based employees will work in a hybrid setting.

What You’ll Do

• Design, build, and maintain core platform infrastructure to support scalable, reliable, and secure services across engineering teams.
• Develop and manage Infrastructure as Code (IaC) using tools like Terraform to ensure consistent, reliable environments.
• Own major architectural decisions and long-term technical direction for Fieldguide’s infrastructure.
• Build reusable platforms, abstractions, and AI-enabled tooling that raise the baseline for engineering teams.
• Monitor and improve system reliability, performance, and cost efficiency through metrics, logging, and alerting frameworks (e.g., Datadog, CloudWatch).
• Ensure infrastructure security and compliance by implementing best practices for identity management, network segmentation, secrets handling, and vulnerability management.
• Lead incident response and postmortem processes, driving root cause analysis and structural long-term improvements.
• Mentor and collaborate with engineers and tech leads, fostering a culture of reliability, automation, and continuous improvement.
• Support disaster recovery and business continuity planning, ensuring high availability and resilience of critical systems.
• Document infrastructure design, architecture decisions, and operational procedures for transparency and team enablement.

Who You Are

• You have 5+ years of hands-on experience constructing complex cloud solutions using multiple AWS services.
• You are skilled in provisioning and configuring cloud services using Terraform and the AWS CLI / API.
• You have proficiency in designing effective monitoring/alerting and log aggregation solutions using tools like Datadog and AWS CloudWatch (New Relic, Prometheus/Grafana, etc.)
• You have a solid understanding of data systems, including both SQL and NoSQL.
• You have experience in developing and maintaining software in security and regulatory compliance environments (SOC 2, PCI-DSS, HIPAA, etc.)
• You are comfortable participating in on-call support to ensure 24/7 availability of services.
• You have a passion for mentoring and coaching other engineers.
• You have excellent communication and organizational skills and are capable of managing multiple competing priorities.
• You have deep expertise designing systems and processes that make engineering teams measurably faster and more effective.
• You can clearly communicate technical strategy to managers and executives.

Bonus Points

• You have experience with GraphQL as a database front-end API.
• You have experience with database system architecture (e.g., Postgres) and observability, to help us increase our overall database performance.
• You have experience both working with AI, and with providing it as a tool for engineers and our internal applications to utilize.
• You have experience working through and designing for security audits (e.g., SOC2, PCI, etc.)
