Sr Software Developers are experienced professionals responsible for designing, developing, and maintaining complex software applications. They typically lead technical teams, make architectural decisions, and mentor junior developers. Their role often involves collaborating with stakeholders to define requirements, ensuring code quality, and staying updated with emerging technologies. Senior developers play a crucial part in the software development lifecycle, helping to deliver robust and scalable solutions.

What are the key skills and qualifications needed to thrive as a Sr software developer?

To thrive as a Sr Software Developer, you need advanced proficiency in programming languages (such as Java, Python, or C#), software architecture, and a bachelor's or master’s degree in computer science or a related field. Familiarity with development tools like Git, integrated development environments (IDEs), cloud platforms, and relevant certifications (e.g., AWS Certified Developer) are typically expected. Strong problem-solving, leadership, collaboration, and communication skills help you mentor junior developers and work effectively within teams. These abilities are crucial to building robust software solutions, driving technical excellence, and ensuring successful project delivery.

Job description

The role

The Senior Software Developer is responsible for the end-to-end design, development, and release of complex software applications and systems. This position requires advanced technical expertise, leadership in software architecture, and cross-functional collaboration to ensure high-quality, secure, and scalable solutions. As a Senior Software Developer on the Admin Platform team, you will design, build, and operate the core services that underpin Evo, our cloud-based geoscience platform. Working within a microservices architecture built on Python, FastAPI, Kubernetes, and GCP, you will lead the development of highly reliable, scalable backend systems that power data organization, permission management, auditability, and integrations. This role also includes project management responsibilities and providing technical guidance and mentorship to team members.

In this role you will have the opportunity to

  • Lead the end-to-end design and architecture of complex software applications and core backend services, using appropriate modeling techniques and leading design reviews to ensure high-quality, scalable solutions.
  • Design, code, test, and refactor complex programs and integration software services, while championing the use of agreed-upon standards and development tools across the team to achieve well-engineered outcomes.
  • Own the release management lifecycle by planning, scheduling, and coordinating software releases across multiple teams, ensuring all deliverables meet defined quality, security, and compliance standards.
  • Define, document, and execute projects by preparing realistic plans, managing risks, and monitoring project resources to ensure alignment with organizational goals and stakeholder expectations.
  • Act as a key technical leader by mentoring team members, enhancing existing processes with emerging technologies, and providing technical guidance in cross-functional collaborations to meet user needs.

Essential Knowledge, Skill and experience

  • Possess a Bachelor's degree in a relevant field and over 7 years of software development experience, including designing, building, and maintaining scalable RESTful APIs, ideally with Python and FastAPI.
  • Bring strong experience with cloud platforms (GCP, AWS, or Azure), deploying services in containerized environments (Kubernetes), and managing cloud resources using Infrastructure as Code (e.g., Terraform).
  • Demonstrate proficiency in designing and maintaining reliable CI/CD pipelines, writing automated tests across multiple layers (e.g., unit, integration), and familiarity with modern frontend technologies like React.
  • Showcase the ability to work autonomously on complex technical tasks, influence stakeholders, facilitate collaboration, and make decisions that impact project success.
  • Combine deep industry knowledge with the ability to communicate complex ideas effectively, drive team development, and apply expertise to ensure security, privacy, and ethical best practices are followed.
