Engineering at Blinq
Our engineering team is the engine behind Blinq’s success. We’re building tools that make sharing who you are instant and human. Every line of code, every release, and every experiment is focused on driving meaningful impact.
Role & Impact
As a Senior Full Stack Engineer at Blinq, you’ll build and maintain the APIs and services powering everything from identity sharing to real-time analytics. You’ll design systems that scale, contribute to architectural decisions, and ensure performance, reliability, and clean abstraction across our platform.
What You’ll Do
Experience building using Node.js and Typescript. Design systems that scale from user onboarding to QR event ingestion. Collaborate with frontend, mobile, and data teams to deliver cohesive features. Improve observability, testing, and service performance. Build features from zero to one in a highly collaborative team.
What You’ll Bring
3+ years in backend development, ideally in fast-paced product teams. Deep Node.js experience, with strong fundamentals in async architecture. Familiarity with GCP or other cloud environments. Good understanding of system design, data modelling, and API security. Clear communicator and collaborator across functions. Familiarity with integrations and MCP.
What you get
Equity and ownership. Competitive salary and a real growth path. Time to switch off. 20 days of annual leave plus a flexible policy for everything life throws at you beyond that. Good times, often. Team lunches, padel, games nights, Barry's sessions. Regular catered lunch at some of our offices, plus an always-stocked snack bar. We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
