Our client is not able to offer Visas or sponsorship to Non‑EU passport holders unfortunately.
Our client is a fast‑growing scale‑up in the Customer Sentiment analysis and insights platform that allows brands to decipher granular customer feedback and feelings towards brands and products and action those learnings with the view towards driving growth.
My client has built a powerful platform used by many global B2C and B2C SaaS subscription businesses to get to the heart of user needs and so they can build better products in‑line with user wishes.
Our client has a lean but mighty but world‑class engineering and R&D team with high ownership, experimentation, and continuous learning.
As we scale, we are seeking a strong Full Stack Engineer where there is future runway for personal growth and assuming more responsibility by becoming a team lead.

Design, implement, test, and maintain features end‑to‑end, from UI / frontend to backend services and data layers.
Collaborate with Product, Design, QA, and other stakeholders to define requirements, ensure high quality, and deliver iteratively.
Write clean, modular, and well‑tested code; Contribute to architectural decisions (scalability, performance, reliability, security).
Mentor and coach junior / mid‑level engineers; Help set engineering processes (CI / CD, code reviews, documentation, testing, deployments).
The aim is to be five days in the office but there is flexibility when required to WFH for life needs.
Qualifications 5 to 7+ years of hands‑on software engineering experience.
Strong experience building full‑stack web applications (frontend + backend)
Deep knowledge of frontend frameworks / libraries (e.g. React, Vue, Angular, Svelte)
Proficiency in one or more modern backend languages / frameworks (e.g. Node.js / Express, Python / Django / Flask / FastAPI, Java / Spring, Go, Ruby on Rails, etc.)
Experience working with relational and NoSQL databases, APIs (REST, GraphQL)
Familiarity with cloud infrastructure (AWS, GCP, Azure) and containerization (Docker, Kubernetes, etc.)
Solid understanding of web fundamentals: security, performance, caching, concurrency
Experience writing tests (unit, integration), CI / CD pipelines, automated deployments
Good communication skills, ability to work in a multilingual / remote‑friendly environment
Fluent English; Spanish / Catalan is a plus (but not mandatory)
Experience with DevOps / SRE practices (monitoring, logging, observability)
Previous experience mentoring or leading engineers, or being tech lead
Familiarity with domain‑specific tooling or domain (e.g. data pipelines, real‑time systems, etc.)
