We build AI and digital systems for organisations that can't afford for them to fail: UN agencies, international organisations, standards bodies, startups, and SMEs.

This is a ground-floor role designed to progress into an Operations Manager or COO as the company grows.

At T4G Lab, we are more than just a tech consultancy. We work with startups, non-profits, universities and United Nations to solve real-world problems in Health, Climate Change, Education, Research or Financial Access. We are looking for a seasoned Full Stack Engineer with deep experience to join our integral team. Track opportunities across portals, commercial channels, outreach and your own network. Bid library, reusable methodology boilerplate, past-performance dossier, CRM, roster, and framework registrations. Python, Django / DRF, REST API design, PostgreSQL, React, TypeScript, data pipelines, AWS clouds, Docker, CD/CI. SPA versus server-rendered tradeoffs, design system budget efficiency, and responsive/accessible implementation costs.
⚬ Can navigate common issues like GDPR, data residency, SSO/SAML/OIDC, ISO 27001, WCAG accessibility, offline-first/low-bandwidth deployments, legacy integrations, and localisation.

If you can explain to a programme officer why their stated requirement is the expensive route to what they actually want,



and propose the cheaper one without losing the bid, you're the person we're looking for.

Preferred) Technical Background: CS degree or equivalent (software engineering, informatics, maths, or a numerate engineering discipline). We prefer teaching commercial craft to a technical person over teaching technology to a salesperson.
⚬ Cross-Functional Experience: Combined experience in software development/management and technical sales, bidding or partnerships.
⚬ Experience developing partnerships, supporting startups or writing public procurement offers.
⚬ Language Skills: Full professional proficiency in English. Spanish is a strong advantage.
⚬ Strong Writing Capability: Ability to produce clear, cohesive technical proposals in client templates.
⚬ Fully remote (Spain-based preferred)
⚬ Tech for Good Impact: Purpose-driven work building mission-critical AI and digital products for UN agencies, non-profits, international organisations, and high-impact startups.
⚬ Collaboration with a global team and an international partnership ecosystem spanning Europe, Asia, America, Africa, and beyond.
⚬ Flexible Working Hours: Output-oriented culture based on trust, autonomy, and flexibility rather than rigid schedules or micro-management.
