Sr Software Developer information

What is a Sr software developer?

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.

What are some typical challenges Sr software developers face when leading project teams, and how can they effectively manage them?

Sr Software Developers often encounter challenges such as balancing coding responsibilities with mentoring junior team members, aligning technical solutions with business goals, and managing project timelines across cross-functional teams. Effective management involves clear communication, setting realistic expectations, and fostering a collaborative environment where team members can share ideas and resolve issues quickly. Leveraging agile methodologies and regular code reviews can also help maintain project momentum and ensure high-quality deliverables.

What is the difference between Sr Software Developer vs Software Engineer?

The roles overlap significantly, but the seniority and leadership aspect distinguish the Sr Software Developer from a general Software Engineer.

Job description

About Us

Modall is a software development agency based in Uxbridge, Ontario. We are a high-performance team of five, partnering with large enterprises, professional athletes, startups, and Web3 pioneers. We build MVPs, AI applications, SaaS platforms, and mobile apps that push the boundaries of modern tech.

Our culture is startup-driven and ambitious. The founders have been building businesses together since 2019 and work with high intensity. We are looking for a developer who matches our drive, values deep focus, and wants to play a significant role in a growing company.

The Role

We are looking for a Frontend Developer with a strong command of React and Next.js to join us onsite. This is not a role for someone who wants to hide in the background. You will work directly with the founders and team to create production-ready software.

While this is a collaborative environment, we value autonomy. We are looking for a developer who is ready to take ownership of features, make architectural decisions, and execute with precision.

Key Details:

  • Location: Uxbridge, ON (Strictly On-site)
  • Type: Full-time
  • Pay: $60,000 - $80,000 per year

What You'll Do:

  • Build: Create dynamic, responsive web applications using React, Next.js, TypeScript, and Tailwind CSS. You will also have the opportunity to build mobile apps using React Native (experience preferred, but not required).
  • Collaborate: Work onsite with experienced developers to translate concepts into clean, production-ready UIs.
  • Own: Manage individual project modules from start to finish, determining the best implementation approach.
  • Optimize: Ensure applications are performant, accessible, and cross-device compatible.

Who You Are:

  • You have 'The Eye': You don't just write code; you care about the final user interface and pixel-perfect implementation.
  • You are 'High Agency': You don't need to be micro-managed. You encounter a bug, you research the fix, and you implement it.
  • You are hungry to build: You want to work on cool projects (AI, Web3, SaaS) and you are willing to put in the focused effort required to ship high-quality products.

Requirements:

  • Proven Experience: Proven proficiency in React and Next.js.
  • Version Control: Comfortable using GitHub (branching, merging, PRs).
  • Design to Code: Experience turning Figma designs into robust code.
  • Education: Post-secondary degree in Computer Science/Software Engineering OR equivalent advanced experience/portfolio.
  • Location: Must be able to commute daily to Uxbridge, ON.

Our Tech Stack:

  • Frontend: TypeScript, React, Next.js, Tailwind CSS, React Native
  • Backend: Node.js, Prisma ORM, PostgreSQL
  • Workflow: Figma, Notion, Jira, Slack

Why Join Modall?

  • Impact: You won't be fixing bugs in legacy code. You will build new products for high-profile clients.
  • Growth: Build products from scratch across multiple industries. You will gain exposure to the entire product lifecycle-from initial strategy, ideation, and design, through to development, DevOps, and QA, and finally post-launch support and feature iterations.
  • Culture: We offer a fast-paced environment where your ideas matter.
  • Perks: On-site gym access, free parking, and a casual dress code.

Schedule

  • Monday to Friday, 9:00 AM to 5:30 PM.
  • Strictly on-site in Uxbridge, ON.

If you have an entrepreneurial mindset, thrive in a startup-style environment, and want to work alongside other developers to play a meaningful role in both client success and product innovation, this is the role for you.

Employment Type: FULL_TIME
