Genesy AI is a Barcelona-based startup on a mission to revolutionize how B2B sales and prospecting teams operate. Our cutting‑edge AI‑driven lead generation technology empowers sales teams to focus on what truly matters: selling. By automating manual prospecting, we help optimize workflows, ensuring a predictable and scalable sales pipeline—no wasted time, just results.

After successfully raising €5 million in a landmark seed funding round, we are looking to grow our teams and scale in key markets.

We’re growing fast and looking for a Software Engineer to join us at Genesy AI. You’ll play a key role in building the systems and user experiences that power our sales‑automation platform, from high‑throughput backend workflows to performant, feature‑rich web applications.

What You’ll Do

Depending on your background and strengths, you will take ownership across one or more of the following areas:

• Build and maintain scalable, reliable services powering our core engine.
• Work with async architectures, data pipelines, and workflow orchestration (Temporal).
• Design and implement production‑grade APIs and integrations with external platforms (CRMs, LinkedIn, and more).
• Optimize performance, debug complex issues, and ensure strong observability.

Frontend

• Develop high‑quality, responsive web applications using React + TypeScript.
• Own customer‑facing dashboards, campaign builders, reporting UIs, and supporting API layers.
• Work on internal tools, SSR/edge rendering, and lightweight Node.js services.
• Focus on performance, Core Web Vitals, and developer experience.

Cross‑functional

• Collaborate closely with Product, Design, and Engineering teams.
• Ship end‑to‑end functionality with a clear focus on quality, reliability, and speed.
• Help shape engineering practices, code quality, and architecture as we scale.

What We’re Looking For (Must‑Have)

• 3+ years of professional software engineering experience (Backend, Frontend, or Full‑Stack).
• Strong experience with TypeScript and either Node.js or React.
• Solid understanding of modern API design, async workflows, or web architectures.
• Experience working with relational databases (PostgreSQL or similar).
• Ability to work autonomously, debug complex issues, and ship high‑quality code.
• Strong communication skills and an advanced level of English.
• Desire to work in a fast‑moving startup environment.
• Experience in early‑stage or fast‑scaling startups.
• Familiarity with workflow engines (e.g., Temporal), distributed systems, or microservices.
• Knowledge of UI performance optimization, design systems, or a11y testing.
• Experience with Redis, Elasticsearch, Kafka, or third‑party API integrations.
• CI/CD practice with GitHub Actions.
• Interest in B2B SaaS, sales tech, or automation tools.
• Basic exposure to full‑stack work, even if your focus is mainly Backend or Frontend.

What We Offer

• Competitive salary based on experience.
• Performance bonuses you won’t find anywhere else.
• Flexible remuneration through Cobee.
• Short Fridays all year, plus extra vacation days (birthday + Geneversary).
• Two weeks of fully remote work from anywhere every August.
• Discount at a premium gym with spa access.
• Free fruit and coffee every day.
• Discount at a beachfront café with daily menu deals.
• Beachfront office with stunning sea views and direct beach access.
• Continuous learning opportunities (mentoring, workshops, conferences).
• Career growth with recognition for your impact.
• Team gatherings and celebrations.
• A collaborative culture based on transparency, teamwork, and respect.
