We seek for an engineer who understands the native mobile lifecycle deeply enough to architect high-performance, mobile-optimized APIs at scale. You will be the technical bridge between native Android and&nbsp;iOS teams and a complex web of travel data partners, ensuring every mobile interaction is fast, reliable, and secure.</p> <p>If you thrive in a fast-paced, collaborative environment and appreciate leveraging your team's expertise to deliver high-quality solutions, this role might be for you!</p> <p><strong>What you'll do:</strong></p> <p>● Architect the Orchestration Layer: Design and maintain scalable, Kotlin-based APIs that aggregate data from multiple enterprise sources into lean, performant payloads purpose-built for mobile consumption, respecting device constraints like battery, bandwidth, and lifecycle state.<br>● Own the Integration Contract: Define and evolve the formal API contracts and schema governance that decouple upstream mobile release cycles from internal platform iteration, enabling independent team velocity without sacrificing stability.<br>● Drive System Performance: Proactively identify and resolve bottlenecks across the API and integration tiers, targeting sub-second response times and high availability within a travel ecosystem that demands real-time pricing, availability, and booking confirmation.<br>● Collaborative Technical Leadership: Engage in high-level architectural discussions and partner with cross-functional teams (iOS, Android, QA, and external partners) to define, design, and ship features that meet enterprise security and compliance standards.<strong><br><br><br>What we're looking for:</strong></p> <p>● The Hybrid Edge: 7+ years of professional software development experience, including substantial work in server-side Kotlin and deep familiarity with the Android SDK. You understand mobile constraints well enough to build backend services that respect them.<br>● BFF Pattern Mastery: Proven track record implementing the BFF pattern with RESTful APIs or GraphQL in high-traffic production environments, not toy projects, but systems handling millions of requests with real SLA pressure.<br>● Architectural Discipline: Comfort operating within established enterprise architectures, navigating complex dependency chains and downstream service tiers, with the judgment to evolve them incrementally without breaking production.<br>● Modern Stack Proficiency: Deep skill in Kotlin Coroutines and Spring Boot, with the ability to design solutions spanning multiple database systems and asynchronous workflows.<br>● Agile Execution: You thrive in Agile/Kanban environments and bring the collaborative instincts needed to work alongside external clients, partners, and vendors with competing priorities.<br>● Ownership Mentality: You don’t wait for tickets. You see systemic issues, propose solutions, and drive them to completion.<br>● Advanced English level.</p><div class="content-conclusion"><p><span style="font-family: helvetica, arial, sans-serif; font-size: 10pt;"><strong>Perks</strong></span></p> <p><span style="font-family: helvetica, arial, sans-serif; font-size: 10pt;">💵 Monthly USD Service Fee</span><br><span style="font-family: helvetica, arial, sans-serif; font-size: 10pt;">🌴 20 business days of paid Agreed Time Off—Annual + 6 Local Holidays</span><br><span class="x19la9d6 x1fc57z9 x6ikm8r x10wlt62 x19co3pv x1g5zs5t xfibh0p xiy17q3 x1xsqp64 x1lkfr7t xexx8yu x4uap5 x18d9i69 xkhd6sd" style="font-family: helvetica, arial, sans-serif; font-size: 10pt;"><span class="xrtxmta x1bhl96m">🐣Caregiver Time Off</span></span><br><span style="font-family: helvetica, arial, sans-serif; font-size: 10pt;"><span class="x19la9d6 x1fc57z9 x6ikm8r x10wlt62 x19co3pv x1g5zs5t xfibh0p xiy17q3 x1xsqp64 x1lkfr7t xexx8yu x4uap5 x18d9i69 xkhd6sd"><span class="xrtxmta x1bhl96m">💻</span></span>A dynamic remote work culture.
