Senior Software Architect

Salary: $13,000 – $19,000 per month

About the role

FoodMax is scaling from thousands of daily orders toward 10,000+ daily orders, alongside growing complexity across multiple suppliers, multiple warehouses, multi-temperature-zone storage, inventory, picking, delivery, and settlement. You'll identify the key architectural risks in current systems, design and drive an incremental evolution roadmap, and personally build out critical modules — safeguarding system stability, data consistency, and engineering velocity as order volume scales. This is a hands-on architecture role where you'll be writing and shipping critical code, not just producing diagrams.

Key responsibilities

• Deeply understand FoodMax's order, product, pricing, inventory, procurement, warehousing, picking, delivery, after-sales, and merchant settlement flows

• Define core domain objects, boundaries, and state machines, with a focus on order splitting, inventory consistency, fulfillment coordination, and exception compensation

• Design scalable, practical system models tailored to fresh food's unique challenges — high-frequency procurement, tight time windows, non-standard/variable-weight items, stockouts, and loss sensitivity

• Set the technical roadmap for evolving toward 10,000+ daily orders, multi-warehouse operations, and platformization

• Dig into existing code and data flows to identify performance, stability, consistency, and maintainability risks

• Personally design and build critical modules, technical prototypes, and shared infrastructure

• Drive idempotency, retry, compensation, reconciliation, and exception-recovery mechanisms across order, inventory, and fulfillment pipelines

• Build capacity models for core pipelines, identifying risks around order-cutoff peaks, batch jobs, message backlogs, database hotspots, and external dependencies

• Establish SLOs, full-chain monitoring, distributed tracing, alerting, and incident diagnosis for core systems

• Build a lightweight, effective architecture review and technical decision-record process

About you

• Bachelor's degree or above in Computer Science, Software Engineering, or a related field, or equivalent demonstrated ability

• 8+ years of software development experience, including 3+ years in architecture, core system ownership, or technical leadership

• Strong hands-on coding ability — genuinely willing to stay hands-on, not just produce plans and reviews

• Track record of leading at least one core system evolution, major refactor, data migration, or stability initiative, with measurable before/after results

• Strong complex business-domain modeling skills — able to extract core objects, states, boundaries, and invariants from business rules

• Solid grasp of idempotency, consistency, state machines, reliable messaging, and exception compensation in order, inventory, payment, settlement, or fulfillment contexts

• Deep familiarity with relational databases, caching, message queues, service governance, and observability stacks

• Skilled in capacity planning, performance analysis, incident diagnosis, disaster recovery, and degradation strategies

• Extensive hands-on use of modern AI coding tools for code comprehension, solution validation, test generation, refactoring, and code review

• Strong communication and cross-functional collaboration skills — able to explain technical solutions to business stakeholders in plain language
