Senior Software Engineer / Technical Lead, C++ Middleware & Interfaces

Summary: Lead the technical delivery of a customised C++ middleware solution in Singapore. You will turn customer and system requirements into a robust software architecture, run day-to-day development, and ensure the interfaces delivered are reliable, testable and maintainable. The role is hands-on and continues into development after the design phase. Responsibilities: • Lead the design, development, integration and verification of customised C++ middleware and software interfaces. • Act as technical focal point for the software work package, coordinating tasks, priorities, estimates, risks and milestones. • Analyse customer, system, interface-control and operational requirements, and derive software requirements and acceptance criteria. • Define the middleware architecture: interface abstractions, data models, message formats, protocol handling, error handling, logging, configuration and service lifecycle. • Build C++ components for inter-system communications, data translation, protocol conversion, message routing and interface monitoring. • Resolve technical ambiguities and integration issues with customers, internal teams and third-party suppliers. • Establish software engineering practices: coding standards, branching strategy, code reviews, build management, unit testing, static analysis and version control. • Plan and supervise the work of a Junior Software Engineer, providing technical guidance, code reviews and mentoring. • Produce design documents, interface descriptions, test procedures, release notes, installation guides and technical reports. • Define and run unit, integration, system and acceptance tests, and support defect investigation and root-cause analysis. • Support installation, deployment, commissioning, customer demonstrations, site integration and post-delivery defect resolution. • Identify technical, schedule, cybersecurity, obsolescence and integration risks, and propose mitigations. • Ensure compliance with customer requirements, project processes, quality procedures and cybersecurity expectations. Qualifications/Requirements: Required • Degree in Computer Science, Computer Engineering, Electrical/Electronic Engineering or a related discipline. • 5+ years of professional software development, with substantial C++ experience (modern C++, ideally C++11 or later). • Proven delivery of production-quality C++ software for distributed, embedded, industrial, maritime, defence, communications, automation or other integration-heavy systems. • Experience designing middleware, software interfaces, communications gateways, protocol adapters or data-integration solutions. • Linux development experience: command-line troubleshooting, process/service management, file permissions, networking tools and log analysis. • Git and structured configuration management. • Debugging, profiling, automated testing and defect investigation. • Ability to interpret interface control documents, protocol specifications, data dictionaries and system requirements. • Strong written and verbal communication, including technical documentation and direct customer engagement. Preferred • TCP/IP, UDP, multicast, serial communications, REST APIs, RPC, publish-subscribe or message-oriented middleware. • Data formats such as JSON, XML, YAML, CSV, Protocol Buffers, ASN.1 or binary message formats. • CMake, Make, Conan, vcpkg, Docker, CI/CD pipelines or automated build/test environments. • Cybersecurity practices: secure coding, authentication, access control, certificate handling, vulnerability management and audit logging. • Experience in regulated, safety-critical, high-availability, maritime, defence, industrial or customer-acceptance environments. • Prior experience technically leading a small team or mentoring junior engineers.
