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.

Senior Software Engineer

About Titan:

Titan is an AI holding company transforming IT services with its Augmented AI platform. We acquire and partner with the best Managed Service Providers (MSPs) and embed AI at the core of their operations, empowering technicians to work faster, smarter, and more strategically. Our augmented AI platform enables MSPs to scale like technology companies while delivering faster resolutions, better uptime, and more proactive, personalized support for their customers.

In under a year, we've raised over $70M from General Catalyst, acquired market-leading MSPs like RFA, and deployed agents seeing real-world impact to productivity. Our team bring together AI product expertise from Scale AI, Google, MIT, and Stanford with private equity experience from H.I.G. Capital and seasoned MSP executives who have led some of the industry's top providers. Joining Titan means helping to redefine how work is done in IT Services and building a $100B company.

About The Role:

As a Senior Software Engineer at Titan, you'll play a pivotal role in shaping the future of AI-powered IT service delivery. You'll work across the stack to build intuitive, high-impact products that blend human expertise with autonomous AI agents, transforming how managed service providers (MSPs) operate. This is an opportunity to join an early-stage team, have meaningful product ownership, and help define the engineering culture as we scale.

What You Will Do:

  • Design, build, and maintain scalable backend systems that power AI-driven automation.

  • Develop APIs and services that integrate AI models into customer-facing applications.

  • Collaborate with AI and frontend engineers to integrate our AI-powered platform into customer-facing tools.

  • Drive technical decisions around system architecture, scalability, and best practices as we scale.

  • Ship fast and iterate, balancing speed with quality in a fast-paced, startup environment.

Who You Are:

  • 4+ years of software engineering experience, with expertise in building and scaling web services.

  • Strong proficiency in Python, Node.js, or Go, with experience in cloud-based architectures (AWS, GCP, or Azure).

  • Familiarity with AI/ML-driven systems or real-time data processing is a plus.

  • User-focused builder - you care deeply about the customer experience and sweat the details.

  • Startup mindset - comfortable with ambiguity, eager to take ownership, and ship quickly.

  • Bonus: Experience integrating LLMs, AI-powered automation, or observability tools is a plus, but not required.
