Barcelona, Spain | Senior Engineering Opportunity
MaxIT Consulting – Max Corporate Group is looking for a Senior
AI-First Full-Stack Engineer to join a fast-growing European
technology company building an AI-powered workforce platform for
the healthcare sector. The company operates a multi-sided
marketplace used by hundreds of hospitals and care organizations
across several European countries, connecting healthcare
institutions with verified nurses, assistants, and doctors. AI is
already embedded into operational workflows, including shift
matching, support automation, and candidate interactions. About the
Role This is a senior, hands-on engineering position for someone
who wants to own outcomes across the full product stack rather than
work on isolated tickets or a single technical layer. AI-assisted
development is part of the standard engineering workflow. The ideal
candidate already uses AI coding tools every day, understands where
they accelerate development, knows where they fail, and rigorously
verifies the output they produce. You will work in a small, highly
technical, founder-led environment with significant ownership over
product and engineering decisions. Key Responsibilities Design,
build, deploy, and operate production web applications end to end.
Work across frontend, backend, databases, cloud infrastructure, and
product workflows. Build modern user experiences using TypeScript
and React or comparable frontend technologies. Develop backend
services using Java, Kotlin, Python, Go, or related technologies.
Design robust SQL schemas for complex, real-time operational
workflows.



Deploy and operate applications in AWS or GCP
environments. Use AI coding assistants as part of the daily
software-development workflow while maintaining strong review and
verification practices. Collaborate directly with product, design,
operations, and customer-facing teams. Take ownership of technical
outcomes from initial problem definition through production
operation. Build secure and reliable systems handling sensitive
healthcare-related information. Required Qualifications 5+ years of
professional software engineering experience. Demonstrated
ownership of production web applications from frontend through
backend and deployment. Strong TypeScript experience and hands-on
knowledge of a modern frontend framework, preferably React.
Professional experience with at least one backend language such as
Java, Kotlin, Python, or Go. Strong SQL knowledge and experience
designing schemas for complex application workflows. Experience
deploying and operating production applications on AWS or GCP.
Daily, practical use of AI coding assistants. Ability to critically
evaluate and verify AI-generated code rather than accepting output
blindly. Strong product mindset and ability to operate with a high




level of autonomy. Nice to Have Experience with containers and
orchestration platforms. Production experience with LLM APIs.
Knowledge of RAG architectures and vector databases. Experience
building agent-based workflows. Exposure to AI evaluation
frameworks. Experience with constraint-solving, scheduling, or
marketplace systems. Previous experience in high-growth product
companies or marketplaces. Adecuado Candidate Profile The strongest
candidate is a full-stack product engineer who is comfortable
owning an entire product surface and does not require a large
platform team or a detailed specification before starting. You
should be comfortable working close to users and business teams,
making technical decisions independently, and using AI as a real
engineering tool rather than an occasional experiment. Compensation
Base salary between €60,000 and €90,000 gross annually , depending
on experience. Early-stage equity participation. Work Arrangement
This opportunity is based in Barcelona, Spain . The exact on-site
versus hybrid working pattern is still being confirmed, so no
