Senior Product Engineer
Confirmed on the employer's own hiring board on Oct 13, 2026. First seen by Alion on Oct 2, 2026.
The next great GTM company is being built in Barcelona
At Enginy we’re building the AI-native GTM platform for modern B2B teams, combining prospecting, enrichment, intent signals, AI research and outreach into one product so sales teams can focus on what truly matters: selling. No wasted time, just results.
We are one of Southern Europe's fastest-growing companies, ranked #3 in the Sifted 100: Southern Europe 2026, and we're just getting started. After raising a €5M seed round, we're scaling internationally and growing the team behind the product. That means more users, more data, more integrations and harder engineering problems exactly at the stage where strong technical leadership has an outsized impact.
We're looking for a Senior Product Engineer who wants to build great software and great engineering teams. You'll lead from the code, set the technical direction for your team, and help define how Enginy builds as the company scales. You'll join early enough to shape the architecture, standards and culture at a stage where customer demand already creates real engineering challenges.
What You’ll Do
Depending on your background and strengths, you will take ownership across one or more of the following areas:
Backend
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)
4+ 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.
Nice-to-Have
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.
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.
Hiring process
We’ve designed our hiring process to be close to real engineering work. We try to avoid trivia-heavy interviews and artificial take-home exercises, and instead focus on how you think through product problems, technical trade-offs, ambiguity, quality, and the use of AI as part of modern engineering.
One of our tech leads wrote more about the philosophy behind the process here: https://oriolcastro.me/posts/hiring-for-modern-engineering/
In practice, you can expect:
- A first conversation to understand your background, goals, and what kind of environment helps you do your best work.
- A short practical task based on a small version of our product, where we care about prioritization, scope, reasoning, and delivery within constraints. You’re welcome to use AI tools, as you would on the job.
- A technical/product conversation focused on realistic engineering problems, not stack trivia.
- A final conversation to align on team fit, expectations, and next steps.
We aim to keep the process practical, transparent, and respectful of your time. If you reach the technical task stage, we’ll review your work carefully and give thoughtful feedback.
What We Offer
Competitive salary tailored to your experience.

Short Fridays all year round and extra days of vacation for your birthday and Geneversary.
