This hybrid role sits at the intersection of application engineering and platform operations - combining the responsibilities of a Full Stack Engineer specializing in Agentic AI and External Integrations with those of a DevSecOps / Platform Engineer.In this role, you will design, develop, and maintain the integrations and intelligent agent capabilities that power a next-generation decision-support platform, while also owning the delivery infrastructure, CI/CD pipelines, cloud operations, and platform health that keep it running securely and reliably. You will work across the full stack to connect AI agents with diverse external data sources, package real-world capabilities as reliable agent tools, and ensure that the systems you build are secure, scalable, observable, and production ready.If you are passionate about applied AI, thrive in fast-moving environments, and take pride in building platforms that real users depend on - from the application layer down to the infrastructure - this is an opportunity to make a meaningful impact supporting critical missions.Location: Columbus, Ohio - candidates must currently reside in the area or be willing to relocate.Key ResponsibilitiesFull Stack & Agentic AI EngineeringDesign and build integrations to external sources of information, including public APIs, licensed data feeds, partner systems, customer enterprise systems, web content, document repositories, and structured databasesPackage external capabilities as agent tools and skills with clean interfaces, predictable inputs/outputs, sound error handling, and documentation usable by both AI agents and human configuratorsDevelop and maintain full-stack components spanning FastAPI/Python backends, React frontends, Docker containerization, and PostgreSQLBuild and consume web APIs (REST, GraphQL, or comparable), handling production integration concerns such as authentication, pagination, rate limiting, retry/backoff, schema mapping, deduplication, and cachingImplement and maintain workflow and task orchestration pipelines using systems such as Airflow, Prefect, Celery, or comparable agent orchestration patternsIntegrate LLMs into production or near-production applications, leveraging APIs such as OpenAI, Anthropic, or AWS BedrockApply security best practices specific to agentic and external integration work - including secrets management, OAuth and API-key handling, defensive parsing, and prompt-injection awarenessCollaborate across teams with a product mindset, keeping the end-user experience central to technical decisions DevSecOps & Platform EngineeringBuild and maintain CI/CD pipelines across GitHub Actions and/or GitLab CI, enabling secure, repeatable, and efficient delivery workflowsImplement and improve automated testing and quality gates within the software delivery lifecycle, including build validation, integration checks, security testing, and deployment controlsPlan and execute releases and deployments - coordinating change windows, managing release artifacts, running deployment automation, validating post-deployment health, and supporting rollback proceduresSupport operational ownership of Amazon EKS / Kubernetes environments, including cluster lifecycle activities, upgrades, troubleshooting, RBAC, Helm-based deployments, pod identity, and GitOps-aligned workflowsBuild and maintain AWS infrastructure supporting platform and application needs across services such as VPC, IAM, S3, RDS, CloudTrail, and KMSContribute to infrastructure provisioning and lifecycle management through OpenTofu / Terraform and related infrastructure-as-code practicesAdminister user management for the platform - identity provider integration (SSO/SAML/OIDC), RBAC, provisioning and deprovisioning workflows, and periodic access reviewsDesign and operate a mature monitoring, logging, and alerting stack using CloudWatch, Prometheus/Grafana, or equivalent toolingRoutinely assess system logs to detect anomalies, configuration drift, misuse, and security-relevant events;
