全职 Senior Software Engineer (WPF, Firmware - Systems) 工作, 薪水 up to SGD 11,000, PAEONIA INNOVATIONS PTE. LTD. Southeast (Singapore) 公司招聘中 - Ricebowl

About the Role

Paeonia Innovations builds OrionIR, a palm-sized inline mid-infrared spectrometer for Process Analytical Technology (PAT) applications, and distributes deep-tech hardware platforms across Asia. We're looking for a versatile, senior-level engineer who can move fluidly across the full stack — from firmware and hardware bring-up, to backend databases and industrial protocol integration, to the software and UI layers our customers actually touch.

This is a generalist role for someone who thinks in systems. You'll be expected to provide architecture designs end-to-end, keep our infrastructure secure, and use AI tools aggressively to move fast — without ever putting our proprietary algorithms or customer data at risk.

JOB RESPONSIBILITIES:

Software Development

• Design, build, and maintain desktop and web applications in C#, Python, and C for instrument control, data acquisition, and analytics.
• Develop and optimize SQL databases underpinning product data, calibration models, and customer-facing reporting.
• Maintain and evolve the company website and any customer-facing HTML/web properties, ensuring uptime, performance, and content accuracy.

Firmware & Hardware

• Write and debug embedded firmware (C) for spectrometer and sensor subsystems, including bring-up on new hardware revisions.
• Work directly with hardware engineers on schematics, signal integrity, and board-level troubleshooting where firmware and hardware intersect.

Industrial Communication & Integration

• Implement and support industrial communication protocols — OPC UA, industrial Ethernet, and MODBUS — for integration into customer PAT and process-control environments.
• Ensure reliable, low-latency data exchange between instruments, plant systems, and our own software stack.

Security Administration & Data Protection

• Own security administration across our software: access control, network security, credential management, and patching.
• Define and enforce policies that protect confidential algorithms, calibration models, and customer data — including strict boundaries on what can and cannot be shared with third-party or cloud AI tools.

AI-Enabled Development

• Make full, deliberate use of AI coding and productivity tools to accelerate development cycles and shorten time-to-deployment.
• Establish safe patterns for AI adoption (e.g., local/enterprise-grade tooling, redaction of sensitive code and data, review gates) so speed never comes at the cost of IP or data security.

UI/UX & Systems Architecture

• Design, prototype, and test user interfaces for both embedded device UIs and companion desktop/web software, iterating quickly with real user feedback.
Own systems architecture end-to-end — hardware, firmware, network, and software layers — making build-vs-buy calls and documenting design decisions for the team.

JOB REQUIREMENTS:

• 8+ years of professional software/firmware engineering experience, ideally spanning embedded systems and full-stack development.
• Bachelor's or Master's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field.
• Proficient and experienced with Windows development in C# on .Net, WPF and WinUI.
• Proficiency in SQL, HTML, Python, and C.
• Hands-on experience with OPC UA, MODBUS, and industrial Ethernet networking in a real deployment context.
• Experience in scientific instrumentation, spectroscopy, or optical/photonics hardware.
• Practical security administration experience: access control, network hardening, encryption, and data governance.
• Demonstrated use of AI-assisted development tools in a professional setting, with clear judgment about what data/code is safe to expose to them.
• Systems-level thinking: able to reason about trade-offs across hardware, firmware, and software rather than working in a single layer.
• Self-directed and comfortable in a small-team, high-ownership startup environment.

Paeonia Innovations is a newly established R&D outfit of Paeonia Ventures, a single-family office based in Singapore with operations in Singapore, Hong Kong, and the USA. The objective is to undertake special innovation projects on behalf of the family office and develop new products in adjacent industries of our operating companies.

In addition, Paeonia Innovations is responsible for scouting new technologies within the testing instruments space at global research institutes and institutes of higher learning (IHLs) with the goal of incubating them into new business lines for internal stakeholders or spin-out companies.
