SDE-1 Contractual

The interview process typically starts with a timed online coding assessment focusing on data structures and algorithms. Successful candidates move to a technical interview that blends system design discussions with live coding on a shared editor. The final HR round evaluates cultural fit, communication skills, and clarifies contractual details. Candidates report a moderate to high difficulty level, with emphasis on problem‑solving speed and clear articulation of design choices.

Cross Border Tech fosters a fast‑paced, data‑driven environment where engineers are encouraged to experiment and ship early. The team emphasizes work‑life balance through flexible hours and remote‑friendly policies, while offering clear growth ladders and mentorship from senior Amazon technologists.

Bachelor's degree in Computer Science, Information Technology, Electronics & Communication, or related engineering discipline; 0–2 years of professional software development experience (non‑internship); minimum 60% aggregate (or CGPA 6.0/10); must belong to the 2025, 2026 or 2027 graduating batch; no active backlogs at the time of joining.

Round 1: Online coding test (platform‑based coding questions) → Round 2: Technical interview (system design + deep‑dive coding) → Round 3: HR interview (culture fit, compensation, contractual terms)

Cross Border Tech is a fast‑growing unit within Amazon that powers the Cross Border shopping experience for millions of customers worldwide. The team builds the end‑to‑end technology stack that enables local language support, local currency conversion, and region‑specific payment methods, allowing shoppers to buy from international marketplaces as if they were domestic. With a mission to simplify global commerce, Cross Border Tech combines large‑scale distributed systems, data mining, and security engineering to deliver a seamless, low‑latency experience across continents. The organization values innovation, customer obsession, and a bias for action, encouraging engineers to experiment, ship quickly, and iterate based on real‑world metrics. As an SDE‑1 Contractor, you will be part of a high‑impact squad that designs, builds, and operates core services for the Cross Border platform. You will work closely with senior engineers, product managers, and data scientists to translate ambiguous business requirements into reliable, scalable software. The role offers exposure to Amazon‑scale infrastructure, real‑time data pipelines, and cutting‑edge algorithms for information extraction and fraud detection. You will also get the chance to influence the platform’s testing framework, CI/CD pipelines, and security compliance processes, making a tangible difference in the speed at which new markets are launched. Key Responsibilities: 1. Design, develop, and maintain micro‑services that handle currency conversion, payment routing, and language localization. 2. Implement robust data extraction pipelines to ingest product catalogs from international sellers. 3. Optimize large‑scale computing workloads for low latency and high throughput. 4. Build automated testing suites and CI/CD pipelines to ensure rapid, safe deployments. 5. Monitor production metrics, set up alerts, and drive incident resolution with a focus on reliability. 6. Collaborate with cross‑functional teams to define API contracts and service level objectives. 7. Contribute to security hardening initiatives and compliance audits. 8. Participate in code reviews, knowledge‑sharing sessions, and technical design discussions. 9. Write clear documentation for services, APIs, and operational runbooks. 10. Continuously research and propose improvements to the tech stack, including adoption of newer languages, frameworks, or cloud services. Tech Stack: Java, Kotlin, Python, AWS (EC2, Lambda, S3, DynamoDB, SQS), Docker, Kubernetes, REST/GraphQL APIs, Terraform, Git, Jenkins, Prometheus/Grafana for monitoring. Growth Path: Successful contractors can transition to full‑time SDE roles, move into senior engineering positions, or specialize in areas like data engineering, security, or site reliability. The exposure to Amazon‑scale systems accelerates learning and opens doors to leadership tracks across the broader Amazon ecosystem. Why Join: You will work on a product that directly impacts global shoppers, gain hands‑on experience with Amazon’s world‑class infrastructure, and be part of a culture that rewards curiosity, ownership, and rapid execution. The contractual nature offers flexibility while still providing a pathway to permanent employment for high performers.
