Senior Software Architect (Global Leadership Rotation Program)

About OptiSigns

OptiSigns is a fast-scaling cloud platform powering digital signage for 30,000+ businesses across 100+ countries, with 190,000+ active screens worldwide.

Founded in Houston, Texas in 2016 and now expanding aggressively in Asia and Europe, we help companies transform ordinary screens into powerful, dynamic communication tools. Our Vietnam engineering team is central to our next phase of growth.

Why This Role

This is not a typical architect role.

We are looking to bring on a senior software engineer from Taiwan to relocate to Ho Chi Minh City, Vietnam, and lead our growing engineering hub. This is a hands-on technical leadership role, with real ownership over both system scalability and team development.

You will lead by example—mentoring engineers, raising the technical bar, and ensuring the team can move fast while building reliable systems.

You will own platform scalability at real-world scale:

• 100M+ database records
• TB-scale customer data
• Rapidly growing global traffic

Your mission is to ensure the system scales reliably while enabling the team to ship faster and with confidence.

This role includes a full relocation package and offers a global career path, including the opportunity to work from our US headquarters as part of our rotation program.

What You’ll Do

• Architect and scale backend systems handling massive datasets and high concurrency
• Own end-to-end performance, reliability, and scalability across the platform
• Optimize databases, data pipelines, caching layers, and backend services
• Proactively identify and eliminate bottlenecks before they impact customers
• Mentor and grow a high-performing engineering team in Ho Chi Minh City
• Collaborate directly with leadership on long-term technical strategy and roadmap

Requirements

• 10+ years of experience in backend / systems engineering
• Proven track record scaling systems to 100M+ records and TB-scale data
• Deep expertise in distributed systems, high-availability architecture, and performance tuning
• Strong database knowledge (PostgreSQL, MySQL, NoSQL, Redis)
• Solid cloud experience
• Strong Node.js / TypeScript background (NestJS or Express a plus)
• Experience with modern backend patterns, data pipelines, and real-time systems
• Excellent English communication and mentoring skills
• Experience mentoring or leading 5-6 junior engineers

Benefits

Why Join OptiSigns

• High-impact role shaping the architecture of a globally used product (190,000+ screens)
• Real-world scaling challenges with tangible business impact
• Strong ownership, high visibility, and direct influence on technical direction
• Opportunity to build and lead a growing engineering team in Vietnam
• Fully supported relocation from Taiwan

What We Offer

• Competitive salary: TWD 2.0M – 3.0M per year
• Performance bonus: 15–25% based on impact
• Opportunity for global rotation program (work in our US office after 1+ year of strong performance)
• Full relocation package (visa sponsorship, flights, Temp housing allowance, onboarding support)
• 13th-month salary, comprehensive health insurance, and standard Vietnam benefits
