This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Software Engineer - Advisory Suite based in Spain.

Join a globally distributed engineering team building high-performance infrastructure for modern financial services.
You’ll develop proprietary services supporting sophisticated advisory products, including portfolio management, block trading, and retirement accounts.
The role offers the opportunity to shape architecture and engineering practices at an early stage, with substantial ownership and autonomy.
You’ll work across frontend and backend systems, databases, distributed architectures, concurrency, and performance optimization.
Your work will directly influence the reliability, scalability, and quality of products used by financial institutions and millions of brokerage accounts.
The environment is highly technical and fast-paced, suited to engineers who enjoy solving complex systems challenges and making critical architectural decisions.
This is an opportunity to make a significant impact while working on demanding, high-throughput financial technology.

• Design, architect, and build proprietary services supporting advisory products such as block trading, portfolio management, and retirement accounts.
• Develop robust, scalable software across frontend, backend, databases, and distributed systems.
• Make critical technical decisions around system architecture, data modeling, scalability, availability, concurrency, and long-term maintainability.
• Build and optimize low-latency, high-throughput systems capable of supporting demanding financial workloads.
• Develop and implement solutions for order management and other high-volume financial transactional systems.
• Work across different levels of the technology stack, from low-level performance optimization to high-level distributed system architecture.
• Contribute extensively to the codebase while taking ownership of engineering quality, reliability, and performance.
• Collaborate within a small, highly technical team where engineers are expected to take on broad responsibilities and wear multiple hats.
• Continuously evaluate and improve system performance through benchmarking, profiling, observability, and technical optimization.

• Proven professional software engineering experience within trading or exchange environments, such as OMS, EMS, exchanges, market making, algorithmic trading, or quantitative trading.
• Strong senior-level software engineering experience, with the ability to independently own complex technical problems.
• Solid system design expertise, including object-oriented data modeling, service-oriented architecture, system abstraction, and distributed system design.
• Strong programming skills across low- and high-level languages such as C/C++, Go, Zig, Rust, Java, Scala, or Python.
• Demonstrated experience optimizing systems for low latency and high throughput.
• Strong knowledge of algorithms, distributed systems, scalability, high availability, databases, concurrency control, and performance-oriented architecture.
• Experience designing or implementing Order Management Systems (OMS) and/or highly loaded financial transactional systems.
• Experience working with messaging queues and message brokers.
• Analytical and data-oriented approach to problem-solving, with strong attention to system behavior and performance.
• Ability to work effectively in an early-stage, fast-moving environment with significant autonomy and technical ownership.
• Knowledge of the FIX protocol is a plus.
• Experience with observability, distributed tracing, continuous profiling, and benchmarking is a plus.

• Competitive salary.
• Stock options.
• Health benefits.
• One-time USD $500 home-office setup allowance for new hires.
• USD $150 monthly stipend through a company expense card.
• Fully remote opportunity within Europe.
• Opportunity to work with a globally distributed team of experienced engineers, traders, and financial technology professionals.
• High level of technical ownership and autonomy.
• Opportunity to work on complex, high-performance financial infrastructure at significant scale.
• Inclusive environment committed to building and supporting a diverse workforce.
