Senior Security Engineer- Spain

About the RoleHopper’s Security team is small by design and consequential by impact, and this role sits at the centre of it.As a Senior Security Engineer, you’ll own the tooling, automation, and processes that keep our applications secure across their entire lifecycle, building the systems that make security invisible to developers and unavoidable by default.This is a builder’s role in every sense: you’ll write code, ship tools, and use AI as a core part of how you work – not as a novelty, but as a force multiplier.What Would Your Day-to-Day Look LikeOwn and evolve our vulnerability management program with a focus on application security – container images, dependencies, code scanning, and runtime detection.Build and maintain security tooling that integrates directly into CI/CD pipelines and developer workflows, so security happens automatically rather than as a gate.Use AI extensively to write code faster, automate analyses that would otherwise require manual review, and build intelligent tooling that scales beyond what a small team could achieve manually.Assess and improve how we leverage available telemetry across our systems.Work directly with engineering teams to influence secure development practices – not by writing standards and documents, but by shipping tools and defaults that make the secure path the easy path.Investigate and respond to security findings when needed, but spend more of your time building systems that prevent and detect issues than manually chasing them.Adapt quickly as priorities shift – our team is agile and tomorrow’s challenge may look different from today’s.An Ideal Candidate HasAt least 5 years of experience in software and/or platform engineering, with the ability to design, build, and maintain production?quality tools.Deep experience in application security and vulnerability management – you understand CVEs, dependency risks, container security, and SDLC integration, and you have opinions about what’s worth fixing and what’s noise.Hands?on experience with cloud infrastructure, ideally GCP/GKE or equivalent, with the ability to adapt to our stack.A demonstrated habit of using AI tools – coding assistants, LLMs – as a core part of how you build and analyze, not an occasional shortcut.A bias toward automation – when you see a repetitive manual task, your instinct is to write a tool, not a runbook.Comfort with ambiguity and ownership – you’ll often be the only person on a problem and will need to make judgment calls on priority, approach, and scope without waiting for direction.Experience influencing engineering culture around security, knowing how to make developers care without slowing them down.Strong written and verbal communication skills, including the ability to articulate our security posture clearly to customers when needed.Perks and BenefitsWell?funded and proven startup with large ambitions, competitive salary, and upsides of pre?IPO equity packages.Hopper covers the cost of employee premiums for private medical and dental coverage.Hopper also offers private life and accident coverage.Very generous parental leave, much above industry standards.Access to co?working space on demand through FlexDesk and Work?from?home stipend.Unlimited PTO.Monthly cash allowance for gym memberships and home?office expenses.Carrot cash travel stipend.Entrepreneurial culture where pushing limits and taking risks is everyday business.Open communication with management and company leadership.Small, dynamic teams = massive impact.Compensation range: $110,000 - $300,000.#J-*****-Ljbffr
