What you will own Build and deliver full-stack features across frontend, backend, APIs, and integrations - from

requirements:through release. Translate product and delivery needs into technical designs, implementation milestones, and maintainable code. Own technical design decisions including data modelling, API design, and system integration patterns. Build and maintain RESTful APIs and service modules that integrate with internal and third-party services. Model, query, and serve data efficiently, with attention to query performance and data integrity. Improve maintainability, reliability, performance, security, and developer experience across the systems you touch. Diagnose and resolve issues across frontend, backend, APIs, databases, and deployment boundaries, including production incidents. Define and uphold coding standards, review code, and mentor other engineers. Participate in code reviews, estimation, and team delivery rituals; document what future engineers need. Core technology stack Frontend: TypeScript, Vue.js, and React (Next.js-style modern web applications), component-driven UI, browser APIs, and frontend state management. Backend / API: Python and Node.js services, REST-style APIs, integrations, background jobs, and service-to-service interfaces. Data: Relational databases such as PostgreSQL - schema design, queries, query performance, and practical data modelling. Delivery: Git and pull-request workflows, automated tests, Docker/containerized services, CI/CD, and basic logging and observability. Quality & security: Web security fundamentals (OWASP), authentication and authorization, and a focus on reliability and maintainability.

What we are looking for Strong professional experience building full-stack web applications with modern TypeScript-based frontends and backend services (Python and/or Node.js).

Ability to design, implement, test, debug, and deploy production-grade features.

Comfort working across frontend, backend, APIs, relational databases, application state, and UI components.

Sound understanding of reliability, performance, security, and maintainability.

Strong Git, debugging, testing, and code-review habits, and a track record of mentoring other engineers.

Willingness to travel up to 50% of the time, on short notice when required (see Travel).

Professional working English.

Travel This role requires a willingness to travel up to 50% of the time.

Travel is need-driven rather than scheduled - when a client engagement, on-site deployment, or operational requirement arises, you are expected to travel as required, including across Asia Pacific and the Middle East.

Nice to have Experience with Python/FastAPI and service-oriented architectures.

Experience with geospatial data or GIS - PostGIS, GeoJSON, GDAL/OGR, spatial queries and indexing.

Experience with map-based visualisation libraries (Mapbox GL JS, Leaflet, OpenLayers, deck.gl) or geospatial APIs.

Authentication and authorization depth (OAuth2, JWT, RBAC); WebSockets and real-time or streaming architectures.

Cloud platforms (AWS, GCP, or Azure), containers, CI/CD, and observability experience.

Experience with data-heavy or enterprise web systems and distributed teams.

Exposure to defense, government, or intelligence-adjacent technology environments.

First 90 days Understand the relevant systems, workflow, delivery context, and current risks.

Deliver scoped improvements with clear communication and review.

Reduce bottleneck pressure in your area by leaving behind maintainable code, documentation, checks, runbooks, or reusable patterns.

How we evaluate We evaluate candidates through a practical full-stack design and debugging discussion, a past feature walkthrough, ownership and code-quality judgment, architectural decision-making, communication, and collaboration.
