com is an AI-powered career platform helping students prepare for and secure internships and graduate roles across investment banking, asset management, private equity and other highly competitive industries.

We are scaling our core technology platform, which combines opportunity tracking, application management, CV scoring, online assessment preparation, HireVue practice, AI mock interviews and personalised performance analytics.

A major part of our roadmap is a reusable, multi-module assessment engine that allows our non-technical team to create and deploy custom-scored psychometric, cultural, numerical, verbal and skills-based assessments without requiring engineering intervention.

We are looking for an experienced, highly autonomous Technical Lead or Senior Full-Stack Engineer to take ownership of our technology architecture and lead our existing team of three developers.

You will inherit a rapidly evolving platform developed using React, https://jobeax.com/link/JSd7UYCSg572jJDY, PostgreSQL, Docker, n8n and AI-assisted development tools including Codex and Replit.

The platform currently runs within a Docker/VPS environment. You will be responsible for stabilising and strengthening the existing codebase, improving engineering governance and leading its migration towards a secure, scalable AWS Serverless architecture backed by Amazon Aurora PostgreSQL.
