• Work closely with peers to architect, implement and operate CI/CD pipelines and automated deployment workflows. Configure and manage development environments and assist in infrastructure-as-code or containerization efforts to streamline releases. Take part in deploying applications to production and monitoring their health, ensuring smooth releases with minimal downtime.
• Collaborate with cross-functional team members - including other developers, DevOps engineers, system administrators, and product stakeholders - throughout the software development life cycle. Participate in Agile/Scrum processes, contribute to planning and design discussions, and clearly communicate technical decisions and progress to ensure alignment. Serve as a bridge between development and operations, fostering a culture of partnership and shared ownership of the final product.
• Stay informed about emerging technologies, frameworks, and best practices in full-stack development. Conduct research and recommend improvements to tools, coding standards, or processes that can enhance our development workflow and product quality.

Skills

• Strong proficiency in multiple front-end languages and frameworks (e.g. HTML5, CSS3, JavaScript, and libraries/frameworks such as React, Angular, or Vue.js) alongside solid back-end development skills with languages like Node.js, Python, C#, Java, or similar (including their associated frameworks). Ability to design user-friendly UIs as well as robust server-side logic and APIs.
• Proficiency with version control systems (particularly Git) and familiarity with continuous integration/continuous delivery (CI/CD) pipelines and tools (e.g. Jenkins, GitLab CI, Github Actions) for automated build and deployment processes. Exposure to modern development workflows and tooling is expected, enabling close collaboration with other team members.
• Strong debugging and problem-solving skills, with meticulous attention to detail in code and system design. Ability to analyze complex requirements or issues across the full stack and devise effective, efficient solutions that align with business needs and user expectations.
• Excellent communication and interpersonal skills to work effectively within a collaborative team environment. Proven ability to explain technical concepts to non-technical stakeholders and to document work clearly. A proactive attitude and eagerness to share knowledge and learn from others are essential, especially as we build a new team culture.
• A track record of contributing to open-source projects, hackathons, or other innovation initiatives is welcomed, as it demonstrates passion for technology and creative problem-solving. Showing initiative in exploring new technologies or sharing knowledge (e.g. via internal knowledge bases or community contributions) is a strong positive.

Education & Experience

• Bachelor's degree in computer science, Software Engineering, or a related field (or equivalent experience). Proven experience (5+ years) as a Full Stack Developer or similar role developing web applications in a production environment. Experience in a fast-paced or highly regulated industry (financial services, fintech, etc.) is highly desirable.
• Master's degree in a relevant field (e.g. Computer Science or an MBA with a technology focus) is a plus. Professional certifications - for example, in cloud platforms (AWS/Azure), security (e.g. CISSP), or software development (Microsoft Certified: Azure Developer, etc.) - are advantageous and show a commitment to ongoing learning.
• Experience working with relational and NoSQL databases (e.g. MySQL, PostgreSQL, MongoDB CosmosDB), including writing complex queries and designing schemas for reliability and performance. Familiarity with web servers and general server administration (Linux/Windows OS, networking basics) to effectively deploy and troubleshoot applications in various environments.
• Good understanding of software security fundamentals (e.g. OWASP top 10, secure coding practices, NIST 800-218 (SSDF)) and experience implementing data protection measures within applications. Awareness of relevant compliance and regulatory considerations in development - especially in finance (such as handling sensitive data, audit logging, or PCI-DSS requirements) - to ensure solutions meet required standards.
• Prior experience developing software for financial services or banking applications. Familiarity with the finance industry's terminology, workflows, and regulatory environment can help you quickly adapt and contribute effectively.
• Experience participating in Agile development teams and familiarity with modern DevOps practices beyond the basics. Knowledge of additional tools and techniques for automation is beneficial; for instance, experience with containerization (e.g. Docker) or infrastructure-as-code can be an asset in our evolving environment.
• An eye for good user experience or past collaboration with designers to create intuitive, user-friendly interfaces is a plus. Experience in performance tuning web applications (both client-side optimization and server-side scaling techniques) helps in building fast, responsive systems that perform well under load.
