Software Engineer Startup information

What are the key skills and qualifications needed to thrive in the Software Engineer Startup position, and why are they important?

To thrive as a Software Engineer in a startup environment, you need solid programming skills, a problem-solving mindset, and a degree in computer science or related experience. Familiarity with agile methodologies, cloud platforms, version control (like Git), and rapid prototyping tools is highly valued, and startup engineers may also benefit from exposure to full-stack development. Adaptability, effective communication, and the ability to work independently in uncertain environments are standout soft skills. These competencies enable engineers to rapidly iterate on products, effectively collaborate across small teams, and contribute to the dynamic demands of a growing company.

What is a Software Engineer Startup job?

A Software Engineer Startup job involves developing, testing, and maintaining software in a fast-paced, early-stage company. Engineers in startups often wear multiple hats, working on both backend and frontend development, infrastructure, and sometimes even product decisions. The role requires adaptability, problem-solving skills, and the ability to work with limited resources. Unlike larger companies, startup engineers may need to prototype quickly, iterate based on user feedback, and contribute to the overall growth strategy. This position is ideal for those who enjoy dynamic environments and taking ownership of projects.

What can I expect from the daily work environment as a Software Engineer at a startup?

Working as a Software Engineer at a startup typically means you'll be part of a small, agile team where roles and responsibilities can shift quickly based on company needs. You'll often participate in daily stand-ups, collaborate closely with founders or product leads, and have the opportunity to contribute ideas beyond your core coding tasks. The pace is usually fast, and you'll likely wear multiple hats, working on everything from prototyping new features to troubleshooting production issues. This hands-on, collaborative atmosphere provides excellent opportunities for skill growth, creative problem-solving, and making a visible impact on the company's direction.

Job description

SRED.io is redefining how companies fund innovation.
We're a fast-growing startup building a cutting-edge, AI-powered platform that helps Canadian businesses unlock SR&ED funding for their most ambitious tech and scientific projects. By combining advanced NLP technology with deep expertise from top-tier SR&ED professionals, we're transforming a traditionally complex, documentation-heavy process into a seamless, intelligent experience.
Our mission is simple: eliminate the friction of SR&ED claims so companies can focus on what matters most - building, experimenting, and pushing innovation forward.
We expect to establish an office in the nearest future and transition to a hybrid setup.
We are actively looking to add multiple Senior level Software Engineers (Mean stack).
What you'll be doing:

  • Design, build, and ship end-to-end features using the MEAN stack (MongoDB, Express, Angular, Node.js) in a fast-moving, product-focused environment
  • Own features from concept to deployment, delivering real-world impact for customers
  • Develop responsive, user-friendly interfaces and scalable REST APIs using a modern tech stack
  • Optimize performance across the application and continuously improve engineering standards
  • Collaborate closely with a small, high-energy team across product, design, and QA
What We're Looking For:
  • 5+ years of full-stack development experience, ideally in a startup or scaling environment with high ownership
  • Bachelor's degree in Computer Science or related field
  • Strong proficiency in JavaScript/TypeScript and the MEAN stack
  • Solid experience with Angular (v10+) and Node.js/Express
  • Hands-on experience with MongoDB schema design and querying
  • Familiarity with Git, CI/CD pipelines, and Agile workflows
  • Comfortable working in a flexible, fast-paced environment with a proactive, adaptable mindset
Why SRED.io?
  • Impactful Work: Help businesses access critical funding and innovation opportunities, making a real difference for companies across Canada.
  • Growth Opportunities: As we scale, you'll have plenty of opportunities for personal and professional growth. At SRED.io, we believe in promoting from within!
  • Innovative Product: Work with cutting-edge AI and NLP technology that's reshaping an entire industry. Be part of a company that's changing the game.
