About Aegis Ventures

Aegis Ventures partners with entrepreneurs and industry leaders to launch and scale transformative companies in digital health and artificial intelligence. Our platform brings together market-shaping ideas, growth capital, and ambitious individuals to solve major societal problems. With a focus on innovations in healthcare, Aegis has launched four successful portfolio companies in partnership with Northwell Health and recently announced the Digital Consortium to co-develop, invest in, and launch new companies.

About Ascertain

Ascertain is a healthcare AI startup based in NYC, founded with the backing and expertise of New York’s largest healthcare system, Northwell, and supported by leading clinical experts from Harvard and Stanford, along with seasoned technologists from Amazon and Google. We’re on a mission to eliminate the manual, tedious administrative tasks that drain healthcare providers’ time, enabling them to fully focus on delivering high-quality patient care.

Our AI-driven platform automates notoriously inefficient processes—such as prior authorizations, discharge planning, claims processing, and pharmacy operations. Leveraging recent breakthroughs in large language models LLMs and advanced automation technologies, we help healthcare enterprises streamline these previously manual and tedious workflows. By eliminating unnecessary burdens, Ascertain empowers clinical teams to focus their expertise where it matters most: patients.

Our team works from our NYC office on a flexible, hybrid basis—we value autonomy and trust our team members to manage their schedules effectively.

About the Job

As a Frontend Software Engineer at Ascertain, you will define and lead the development of Ascertain’s user-facing applications. As one of our earliest engineering hires, you’ll shape our frontend strategy, select modern technologies, and establish best practices that will influence our engineering culture for years to come.

You’ll collaborate directly with product, design, and customers, ensuring we build intuitive, user-focused solutions that genuinely solve complex healthcare challenges. While your primary focus will be frontend, our team is small and we value engineers who can make backend changes when needed to fully own a feature.

What You’ll Do:

  • Design and develop intuitive front-end applications using React and TypeScript.
  • Work closely with product managers, designers, and other engineers to define technical requirements and translate them into robust software solutions.
  • Participate in code reviews, providing constructive feedback and ensuring high-quality code standards.
  • Mentor junior developers and contribute to fostering a collaborative engineering culture.
  • Contribute to improving software development processes and best practices.

What You’ll Need:

  • 7+ years of experience in front-end development using React and TypeScript.
  • Some back-end experience to integrate comfortably with APIs and pragmatically contribute across the stack as needed.

What You’ll Bring to the Table:

  • A strong product mindset—you genuinely want to understand our customers, challenge assumptions, and directly influence product decisions.
  • Experience in ambiguous startup environments, proactively take ownership, and communicate clearly across teams.
  • Excitement (not just willingness!) to dive into new technologies, learn quickly, and step beyond your comfort zone in a rapidly evolving environment.

Benefits & Perks:

  • Cutting-edge technology: Work directly with the latest advancements in generative AI and automation, tackling challenging problems that meaningfully impact healthcare.
  • Ownership & growth: You’ll join Ascertain at a pivotal early stage, shaping our products, technical direction, and culture, with significant opportunities for career advancement.
  • Collaborative team: Join a talented, passionate, and supportive team with backgrounds from top tech companies and clinical institutions.
  • Flexible hybrid work: We support a flexible hybrid working model from our NYC office, trusting you to manage your own schedule.
  • Competitive compensation: We offer competitive salary, meaningful equity, comprehensive health insurance, and more.

Salary Range:

  • $180,000 - $280,000 base salary, depending on previous experience and alignment with role expectations.

Why Ascertain? Make a real difference: Your work will directly impact healthcare organizations and improve patient care. Join Ascertain in transforming healthcare with AI!
