Senior Software Engineer

Schneider Electric is a global leader in digital transformation, automation, and software-driven solutions for buildings and critical infrastructure. Within the Digital Energy – Software organization, we are expanding our engineering presence in Bangalore to accelerate the EcoStruxure Foresight platform, including a secure, next-generation integrations capability.

Job Description

We are seeking a Senior Software Engineer – Integrations (WebAssembly / Rust) to design and build integrations for third-party systems using a WebAssembly-based approach. The primary responsibility of this role is to develop WebAssembly (Wasm) modules that integrate external APIs and interact with host-provided APIs in a secure sandboxed environment.

The integrations platform is built around a WebAssembly runtime with WASI support and a contract-based model for defining module interfaces. You will primarily develop integration modules in Rust, and may also work with other supported languages that compile to WebAssembly. The role also requires a solid understanding of how the runtime and host execute these modules, with the ability to contribute to runtime improvements when needed.

Key Responsibilities

Integration Module Development (Primary)

• Design and implement WebAssembly modules/components for third-party integrations, primarily using Rust.
• Integrate with third-party systems using supported communication patterns such as HTTP-based APIs and event-driven workflows.
• Handle authentication, error handling, retries, rate limiting, and resilience in integration logic.
• Define and maintain clear module interfaces and contracts, ensuring compatibility and long-term maintainability.
• Build, package, version, and release Wasm modules using standard Rust tooling, including Cargo, as part of a production-ready workflow.

• Understand how the WebAssembly runtime executes sandboxed modules and contribute improvements related to validation, lifecycle management, and diagnostics.
• Work with host-mediated access patterns where outbound calls are controlled to enforce policy and securely manage credentials.
• Contribute to developer enablement through templates, examples, tooling, and documentation for building integrations on the platform.

• Implement testing strategies for integration modules and contribute to automated quality gates.
• Ensure integrations follow secure-by-design principles, including isolation, resource limits, and safe credential handling.
• Add observability to integration execution through structured logging, metrics, and error reporting to support production operations.

• 5–10+ years of experience in software engineering with strong hands-on backend development.
• Strong proficiency in Rust and C++, with experience building production-grade services or libraries.
• Practical experience building and shipping WebAssembly (Wasm) artifacts.
• Hands-on experience with Rust tooling, including Cargo, and build workflows for Wasm modules.
• Working knowledge of WASI and contract-driven integration patterns between host platforms and sandboxed modules.
• Experience defining and working with WIT (WebAssembly Interface Types) interfaces for host ↔ module contracts, including versioning and backward compatibility.
• Experience with Wasmtime, including understanding how components are loaded, linked, and executed; hands-on experience with the Wasmtime C API to embed or extend runtime capabilities.
• Experience defining stable interfaces and versioning strategies for integrations and APIs.
• Solid experience integrating with external systems and APIs, including debugging and operational support.

• Strong problem-solving skills and ability to work effectively in ambiguous or evolving technical areas.
• Clear communication and ability to collaborate with architects, DevOps, frontend teams, and global stakeholders.
• Ownership mindset with the ability to drive an integration from design through production readiness.

• Familiarity with secure sandbox design, isolation, and policy enforcement.
• Exposure to integration-heavy platforms, security systems, or building automation domains.

• Btech
