Staff Engineer - Cross Border

Accountabilities

• Define technical direction:Shape the architecture of cross-border backend systems supporting international customers purchasing from Japanese marketplace sellers.

• Lead cross-team system design:Coordinate architecture across the entire purchasing journey, including discovery and search, product details, pricing, landed costs, checkout, payments, and post-purchase experiences.

• Establish clear service boundaries:Define robust API contracts and Backend-for-Frontend (BFF) patterns that support iOS, Android, and web applications.

• Build scalable backend services:Design, develop, test, and maintain reliable Go services while remaining hands-on with complex technical challenges and critical implementation work.

• Enable global platform scalability:Develop systems that support multiple regions through a consistent global platform, avoiding unnecessary country-specific fragmentation.

• Own production reliability:Establish standards for observability, safe deployments, incident response, and continuous operational improvement across marketplace services, partner integrations, payment systems, and third-party providers.

• Accelerate engineering delivery:Help two to four engineering teams overcome complex design challenges, simplify platform architecture, and improve delivery speed and quality.

• Advance AI-assisted engineering:Integrate coding agents, AI-assisted code reviews, automated testing, debugging, and operational automation into the software development lifecycle.

• Drive cross-functional alignment:Collaborate with product managers and engineers across India and Japan to turn ambiguous business and technical challenges into actionable engineering plans.

• Mentor technical leaders:Coach senior engineers, strengthen architectural decision-making, and help engineering teams use AI agents effectively while maintaining high standards of software quality and reliability.

Requirements

• Professional experience:10–12 years of software engineering experience, including demonstrated leadership of complex backend initiatives spanning multiple teams.

• Backend engineering expertise:Strong experience with Go or the ability to become productive in Go quickly, including API design, implementation, and testing.

• Distributed systems:Deep knowledge of designing, building, and operating distributed systems in cloud-native environments, particularly Google Cloud Platform (GCP) and Kubernetes.

• System architecture:Excellent system design, data modeling, production debugging, and architectural decision-making skills.

• Production reliability:Experience operating customer-facing systems at approximately 99.95% availability, with a strong understanding of observability, incident management, and reliability engineering.

• Customer-facing product delivery:A proven record of delivering large-scale, customer-visible product capabilities rather than focusing exclusively on internal services.

• Technical leadership:Ability to influence architecture and engineering standards across multiple teams without relying on formal authority.

• AI-enabled development:Practical experience applying AI or large language models (LLMs) to improve engineering productivity through coding agents, AI-assisted reviews, testing, debugging, or similar workflows.

• Communication and collaboration:Strong written and verbal communication skills, including the ability to explain architectural decisions, technical trade-offs, and risks to technical and non-technical stakeholders.

• Cross-border commerce knowledge:Experience with international e-commerce, payments, multi-currency transactions, or multi-region systems is an advantage.

• Search and data platforms:Familiarity with search, personalization, Elasticsearch, event streams, or machine learning pipelines is desirable.

• Client and API architecture:Experience with BFF patterns and familiarity with React or mobile application clients is beneficial.

• External integrations:Experience integrating third-party partners and external APIs at scale is an advantage.

• Platform engineering:A track record of simplifying technology stacks, improving shared platforms, or driving platformization initiatives is valuable.

• AI tooling development:Experience developing AI agents or AI-powered developer tools is a plus.

• Learning mindset:Willingness to learn the Japanese marketplace domain, internal platforms, and cross-border requirements involving duties, taxes, logistics, and regional regulations.

• Leadership approach:A collaborative, proactive mindset that balances bold architectural thinking with practical execution, shared ownership, and a commitment to engineering excellence.

Benefits

• Employment type:Full-time position.

• Work arrangement:Hybrid working model based in Bengaluru, India.

• Weekly flexibility:The stated working arrangement includes two days per week in the office and three days working remotely.

• In-person collaboration:Team members are encouraged to work from the Bengaluru office, particularly during the initial office setup phase, to strengthen collaboration and organizational development.

• Professional impact:Opportunity to influence the architecture of a global e-commerce platform and contribute to expansion into additional international markets.

• Technical ownership:A hands-on staff-level engineering role with significant influence over system design, platform reliability, and cross-team engineering standards.

• AI-driven innovation:Opportunity to help define how engineers and autonomous AI agents collaborate across software design, development, testing, deployment, and operations.

• Mentorship and leadership:Scope to develop senior engineers and strengthen technical leadership across distributed engineering teams in India and Japan.

• Salary and additional benefits:Compensation, healthcare coverage, bonuses, equity, paid leave, and other benefits are not specified in the available job description and should be confirmed during the hiring process.
