Senior Full-Stack Software Engineer

About the Team

We build full-stack products that combine highly interactive React interfaces with scalable Java backend systems. Because our software runs in demanding operational environments where connectivity can be highly volatile, we don't just build for the happy path. We place deep focus on architecture that handles flaky networks gracefully, utilizing advanced client-side persistence, background sync, and intelligent failure-recovery workflows.

What you will do

As a Senior Full-Stack Engineer, you will act as a technical anchor for the team. You will move seamlessly across the stack, taking high-impact features from initial technical discovery through to production-ready implementation, automated testing, and release. Communicating with key stakeholders throughout the development lifecycle.

Key responsibilities include:

• Architect & Deliver Features: Lead the technical design and implementation of resilient, end-to-end full-stack features using React, TypeScript, Java, and Spring Boot.
• Embed AI tools: Such as Claude Code, Codex, Gemini, and GitHub Copilot — into your daily workflow: accelerating delivery, raising code quality, automating repetitive engineering work, and identifying process improvements others miss. Mentoring team members in well established practices.
• Drive Resilience Strategy: Define and implement robust client-side and edge strategies to ensure application availability in environments with unstable connectivity, managing complex local data lifecycle, state synchronization, and fault-tolerant retry flows.
• System Integration & Security: Oversee secure, decoupled service-to-service communication, maintaining strict API governance, schema contracts, and boundary protections across internal ecosystems.
• Establish Engineering Standards: Define the overarching automated testing strategy for the product, balancing rapid delivery with rigorous multi-tier testing methodologies to minimize production risk.
• Telemetry & Observability: Embed advanced monitoring, tracing, and proactive alerting frameworks across the application stack to maintain operational health and analyze system behavior.
• Technical Leadership: Champion architectural integrity, lead code reviews, minimize technical debt, and mentor engineering peers to elevate the team’s delivery standards and engineering velocity.

What we are looking for

We are looking for a pragmatic, senior-level engineer who values simplicity, testability, and operational excellence. You should be comfortable navigating complex, distributed systems and making high-stakes decisions regarding client-side data state and backend edge APIs.

Essential Skills & Experience:

• Advanced Full-Stack Expertise: Strong core Java background coupled with extensive practical experience building and maintaining enterprise Spring Boot applications, alongside solid experience in modern React (v18+) and TypeScript.

API Design & Distributed Systems: Deep understanding of HTTP API principles, asynchronous service-to-service integrations, cloud data modeling, and session management.

• Operational Ownership: Proven track record of owning software throughout its lifecycle—from whiteboarding architectures through to troubleshooting tight SLA production issues using telemetry dashboards.
• AI & Engineering Efficiency: Comfort utilizing agentic coding tools and LLMs responsibly to accelerate delivery without compromising review standards or code quality.

Desirable Skills & Experience:

• Advanced PWA Capabilities: Prior exposure to complex client-side caching strategies, Workbox, service worker updates, and local database management via IndexedDB.
• State & Query Management: Professional experience working with Redux Toolkit and RTK Query to manage intricate asynchronous UI states.
• Cloud Infrastructure: Hands-on experience with AWS, specifically utilizing DynamoDB (with the AWS SDK v2 Enhanced Client) and S3 for dynamic asset delivery.
• Build Optimization: Experience configuring Gradle build tasks
• DevOps (CI/CD pipelines, Infrastructure as Code, observability tools, resource management).
• Domain Expertise: Background in logistics, supply chain, fulfilment, automated warehousing, or operationally intensive environments.
• Data Analytics solutions (GC Looker, Big Query, etc.).
