We are looking for a Senior Full-Stack Software Engineer to take substantial ownership of the platform, its infrastructure, and its production deployments. This is a full-stack role in the literal sense: you will work across backend services, cloud infrastructure, deployment automation, frontend applications, identity, authorization, data systems, and isolated AI-agent execution environments.

Backend and infrastructure expertise are baseline requirements. Strong frontend expertise is an additional advantage.

What You Will Do-- Build and operate Python services, APIs, CLIs, and full-stack workflows using Type Script, React, and Next.

Js.Provision and run GCP and Kubernetes infrastructure through Pulumi, including databases, object storage, networking, secrets, deployments, and recovery procedures.

Build secure execution environments for AI agents, covering sandbox lifecycle, tool access, workload identity, network isolation, resource limits, and persistent sessions.

Integrate model providers and agent SDKs, including streaming, tool calls, cancellation, and long-running execution.

Implement authentication, RBAC, least-privilege access, auditability, and compliance requirements as enforceable technical controls.

Own production reliability across application and infrastructure layers through testing, observability, performance analysis, incident diagnosis, and safe deployments.

Design and ship agent-driven user experiences spanning chat, files, interactive tools, and data-intensive workflows.

What We Are Looking For 5+ years of full-time software engineering experience in production environments.

Strong Python and Type Script skills and the ability to work effectively across frontend and backend code.

Strong SQL and database fundamentals, including schema evolution, transactions, concurrency, access control, and operational recovery.

Production experience with Kubernetes and at least one major cloud platform, preferably GCP or AWS.

Experience with infrastructure-as-code, preferably Pulumi or Terraform.

Strong understanding of containers, Linux, networking, secrets, service identities, and deployment automation.

Experience designing authentication, authorization, RBAC, and audit-sensitive workflows.

Experience leading substantial deployments or owning production services after release.

Strong judgment regarding least privilege, data residency, encryption, sensitive-data handling, and secure software design.

High daily engagement with modern AI development tools such as Claude Code and Codex.

Ability to work with non-technical stakeholders and translate operational needs into reliable software.

Nice to Have Deep frontend expertise with Type Script, React, Next.

Js, streaming interfaces, and complex interactive applications.

Experience building developer tools, command-line applications, agent harnesses, or AI-assisted coding environments.

Experience with healthcare, biotechnology, pharmaceuticals, finance, or similarly regulated systems.

Knowledge of HIPAA, GDPR, GxP, audit-trail requirements, or regulated software validation.

Experience delivering infrastructure or software platforms for pharmaceutical or healthcare customers.

Familiarity with analytical data systems, knowledge graphs, ontologies, or data-integration platforms.

Experience designing and testing controls for software subject to formal security, privacy, or regulatory review.

Education Master’s degree in Computer Science, Software Engineering, Mathematics, Engineering, or a related technical field.
