Job summary

Caseware is seeking a senior software engineer to lead architecting and delivering cloud-native, multi-tenant SaaS platforms. You will work on AWS-based gateway layers, MCP protocols, and OpenAPI contracts, guiding teams through design and implementation with a focus on reliability, security, and performance.

You will mentor engineers, influence architectural decisions, and drive AI-assisted development practices while collaborating with Product, Security, and Operations.

Qualifications

• 8+ years of professional software development experience with impact beyond a single team.
• Experience designing and operating distributed, cloud-native SaaS platforms at scale, ideally on AWS.
• Strong fundamentals: OOP, design patterns, SOLID, and code quality advocacy.
• Experience with agentic-AI software development practices.
• Experience designing and consuming well‑designed HTTP APIs (REST, GraphQL, or similar).
• Experience mentoring developers and influencing architectural decisions across teams.
• Strong written and verbal communication skills; English at high B2.
• Strong initiative to improve processes, tools, methodologies, and product quality.

Responsibilities

• Build and operate the AWS AgentCore Gateway layer and the capabilities it hosts — MCP tool targets today, extending to inbound access, agent-to-agent targets, and inference/model-routing targets as those capabilities come online.
• Develop and maintain the target registry and configuration model that lets customer firms register their own MCP servers for their agents to call, covering tenant isolation, credential handling, allowlisting and egress control, and containment when a third-party endpoint fails or misbehaves.
• Build the inbound surface that exposes Caseware capability to external agents and clients over MCP and adjacent protocols, including authentication, scope enforcement, and rate limiting.
• Build and operate the on-premise connectivity path, including session lifecycle, request correlation, and recovery for long-lived sessions between cloud-hosted agents and on-premise desktop clients.
• Implement session and scope propagation from agent to gateway to target to backend, so authorization is correct and auditable at every hop.
• Design and evolve OpenAPI contracts for gateway targets, and the target runtimes that implement them, keeping conventions consistent regardless of what a target fronts.
• Implement outbound authorization for gateway targets so access to each target type is securely and consistently controlled.
• Maintain versioning of target contracts as they evolve, so consuming teams and customers are not broken by change.
• Contribute to end-to-end tracing and SLOs for gateway traffic, and build the observability that lets you and other teams detect and debug failures anywhere in the pipeline.
• Mentor other developers joining the team, and contribute to technical direction for the integration layer through RFCs and design reviews.
