Staff Software Engineer (Cloud Infrastructure)

Join Altruist as a Staff Software Engineer (Cloud Infrastructure) and lead the architecture, building, and operation of our AWS-based infrastructure. You will own critical infrastructure domains, drive technical decisions, and shape infrastructure strategy. This role requires deep AWS and Kubernetes expertise, as well as the vision to define how AI/ML tools can transform infrastructure operations.

• Architecting, building, and operating the AWS-based infrastructure that powers the broker-dealer and clearing platform.
• Owning critical infrastructure domains end-to-end and driving technical decisions that affect the reliability, security, and scalability of systems.
• Leading cross-team initiatives, aligning stakeholders, unblocking other engineers, and representing infrastructure perspectives in leadership discussions and planning.

• Deep expertise in CI/CD platforms (GitHub Actions, ArgoCD, Jenkins) with experience designing deployment strategies for multi-service architectures
• Proven experience designing and operating observability platforms (Datadog, Prometheus/Grafana, CloudWatch, OpenSearch/ELK) at organizational scale
• Excellent technical communication skills — ability to write clear ADRs, present to leadership, and translate infrastructure complexity for non-technical stakeholders
• Expert-level proficiency with Terraform, including module design, state management strategies, and establishing IaC standards for engineering teams
• Strong Linux systems engineering skills and advanced scripting proficiency (Python, Bash, or Go)
• Extensive production experience operating Kubernetes (EKS strongly preferred) at scale — cluster lifecycle management, multi-tenancy patterns, Helm governance, and GitOps workflows
• Strong experience with database infrastructure and data layer architecture (Aurora PostgreSQL, RDS, ElastiCache/Redis, OpenSearch, DynamoDB)
• Demonstrated ability to lead disaster recovery planning, execute DR simulations, and design HA architecture patterns for mission-critical systems
• Track record of owning and driving infrastructure initiatives end-to-end — from design and architecture through implementation, rollout, and operational excellence
• 7+ years of hands-on experience in cloud infrastructure engineering, with deep, production-proven expertise in AWS
• Proven track record of mentoring engineers and elevating team capabilities through knowledge sharing, design reviews, and tooling improvements
• Expert-level understanding of cloud networking (VPC architecture, Transit Gateway, peering, DNS, load balancing) and security (IAM, KMS, WAF, GuardDuty, Secrets Manager)
• If you’re excited about this role, but your past experience doesn’t align perfectly with every qualification in the job description, we encourage you to apply anyways. You may be just the right candidate for this or other roles
• Experience in financial services, fintech, broker-dealer, or other heavily regulated industries with FINRA/SEC compliance requirements
• Demonstrated experience with AI/ML infrastructure: provisioning GPU compute, SageMaker/Bedrock integration, vector databases, MLOps pipelines, or AIOps automation in production
• Contributions to open-source projects, conference talks, or published technical writing
• Proficiency with policy-as-code frameworks (OPA/Rego, Sentinel, Kyverno) for infrastructure governance and compliance automation
• Experience authoring RFCs, ADRs, or technical strategy documents that influenced engineering-wide decisions
• 7+ years of infrastructure or platform engineering experience, including 5+ years operating at a senior or staff level
• Experience defining and executing organizational rollout strategies for AI developer tools, including governance frameworks, usage analytics, and cost management
• AWS certifications at the Professional or Specialty level: Solutions Architect Professional, DevOps Engineer Professional, Security Specialty, or Machine Learning Specialty
• Hands-on experience with API gateway management and platform design (Kong, AWS API Gateway)
• FinOps certification or demonstrated experience leading cloud cost optimization programs at scale
• Experience with event streaming platforms at scale (Amazon MSK / Apache Kafka) including cluster operations, partition strategy, and consumer group management
