The Company:

Placements.io is a product-first company transforming how digital media publishers and eCommerce businesses manage advertising operations. Our SaaS platform streamlines sales, operations, billing, and revenue reporting, creating a connected ecosystem that helps our customers scale efficiently. Headquartered in Seattle, we expanded globally in 2023 with offices in New York, London, Taipei, Denver, and Singapore.

The Position:


We are looking for a Backend Engineer to join our growing engineering team in Taipei. In this hybrid role (three days per week in office), you will be a key contributor to the design, development, and maintenance of our advertising technology platform. You’ll work alongside a talented team and collaborate cross-functionally to deliver high-quality, scalable solutions that support our clients’ evolving needs.

Placements.io continues to invest in platform innovation, including the integration of AI-driven features to enhance automation, predictive insights, and reporting performance. If you're passionate about backend development and interested in shaping the future of AdTech with AI, this is an excellent opportunity.

Our tech stack includes

  • Ruby on Rails
  • PostgresSQL
  • Elastic search

The Engineering team tackles a wide range of challenges—from big data and system scalability to improving user experience. You’ll have opportunities to work across the stack, or specialize deeply in backend services.


Key Responsibilities:
  • Design, build, and maintain robust, scalable APIs and backend services.

  • Collaborate with product managers, designers, and engineers to define technical specifications.

  • Implement backend logic to support AI-enhanced features like automated workflows and intelligent data reporting.

  • Optimize system performance and resolve bottlenecks and bugs.

  • Participate in code reviews to ensure quality, knowledge sharing, and maintainability.

  • Conduct testing and debugging to maintain a stable and secure platform.

  • Stay informed on backend and AI technology trends to drive continuous improvement.

  • Contribute to agile ceremonies, including sprint planning and daily stand-ups.

Qualifications:
  • Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field.

  • Strong backend development experience, ideally within a fast-paced tech environment.

  • Proficiency in Ruby on Rails or a similar backend framework.

  • Experience developing and consuming RESTful APIs.

  • Solid understanding of relational databases (PostgreSQL preferred).

  • Familiarity with frontend technologies (React.js, JavaScript, HTML/CSS) is a plus.

  • Experience or interest in working with AI/ML-powered systems, tools, or APIs.

  • Familiarity with cloud platforms such as AWS, Heroku, or Google Cloud.

  • Strong problem-solving skills and attention to detail.

  • Excellent collaboration and communication skills.

  • Experience in the digital advertising or martech industry is a plus.

Benefits Include (subject to company policy changes permitted by law):
  • Competitive salary
  • Early-stage stock options
  • 20 days of PTO
  • Applicable labor insurance and pension fund
  • Company paid medical, dental, vision, and life insurance
  • Regular company lunches and happy hours
  • Gym membership reimbursement
  • Cell phone reimbursement

To apply to our open positions, please email your resume, cover letter, and the name of the position you are applying for to [email protected]. We look forward to meeting you!
