This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Architect based in Spain.

This is a senior-level architecture opportunity for an experienced software engineering leader supporting multiple technology-driven businesses.
You will operate as a fractional CTO, helping founders translate business priorities into realistic technical strategies and high-quality products.
The role combines architecture, hands‑on technical guidance, developer coaching, code reviews, and product‑oriented problem solving.
You will work across several projects, partnering closely with founders, product owners, engineers, and multidisciplinary delivery teams.
Beyond client‑facing work, you will contribute to improving engineering practices, recruitment, training, and internal technology capabilities.
The environment is highly autonomous and collaborative, with flexibility to work full‑time or begin on a part‑time basis.
This role is ideal for a technically strong architect who enjoys variety, strategic influence, and helping teams build scalable solutions in a startup‑focused environment.

Accountabilities

• Act as a fractional CTO for approximately 2–3 technology businesses, providing technical leadership, architecture guidance, and strategic direction.

• Work directly with founders and product owners to understand business priorities, challenge assumptions when needed, and translate requirements into realistic and actionable technical solutions.

• Review and evolve software architecture and system designs to ensure scalability, maintainability, security, and alignment with product goals.

• Protect engineering teams from unnecessary complexity while helping prioritize technical work according to business needs.

• Conduct frequent code reviews, provide technical mentorship, and coach developers toward stronger engineering practices.

• Perform technical code audits for potential investments, clients, or new projects, identifying risks, opportunities, and areas for improvement.

• Provide hands‑on support for complex technical challenges, including software development, DevOps, infrastructure, and troubleshooting when required.

• Contribute to the continuous improvement of engineering teams through recruitment support, training initiatives, knowledge sharing, and technical standards.

• Participate in candidate assessments, technical interviews, and occasional research into emerging frameworks and technologies to strengthen training and development programs.

• Support occasional in‑person founder or investment meetings and provide specialized technical consulting across other projects when relevant.

Requirements

• At least 15 years of professional experience in software development, with extensive experience progressing into senior technical leadership or architecture roles.

• Expert‑level proficiency in Microsoft C#/.NET or Node.js.

• Mastery of React, with experience in Angular or Vue considered an advantage.

• Extensive experience with relational databases such as MySQL, Microsoft SQL Server, MariaDB, or PostgreSQL.

• Strong experience with both Microsoft Azure and AWS, with solid DevOps knowledge considered a plus.

• Experience with Ionic and React Native is advantageous.

• Familiarity with additional technologies such as Python, Java, Kotlin, iOS/Swift, or Golang is a plus, particularly for supporting diverse technical environments.

• Strong understanding of software architecture, system design, development practices, cloud technologies, and modern engineering workflows.

• Proven ability to communicate effectively with founders, business stakeholders, product teams, and engineers, translating between business objectives and technical execution.

• Strong coaching, mentoring, analytical, and problem‑solving abilities, with the confidence to challenge decisions constructively and guide teams toward pragmatic solutions.

• Comfortable working autonomously across multiple projects and adapting quickly to different products, technologies, and organizational contexts.

• Willingness to participate in occasional in‑person client or founder meetings when needed.

Benefits

• Fully remote working environment within Europe.

• Flexible working schedule, with freedom to choose working hours within reasonable business requirements.

• Possibility to work full‑time or start on a part‑time/hourly basis, depending on availability and mutual fit.

• Opportunity to operate in a fractional CTO capacity across multiple technology businesses.

• Diverse technical challenges and exposure to startups, founders, products, and emerging technologies.

• Opportunity to contribute to engineering strategy, recruitment, training, and internal technology initiatives.

• Annual company trip to visit colleagues in the Philippines.

• Flat management structure with an open‑door culture and minimal micromanagement.
