ABOUT US:

Blockhouse is a trading technology company building advanced quantitative research models for financial markets. We’re looking for an exceptional Backend Engineering Intern to join our NYC team full-time in person. This is an opportunity to ship production-grade code alongside a small team of highly technical founders and engineers.

KEY RESPONSIBILITIES:

• Build and scale backend systems that underpin trading infrastructure, real-time data ingestion, and API infrastructure.
• Help design and implement robust ETL pipelines using modern tools and frameworks.
• Write clean, well-documented code in Go, Python, and TypeScript that is built to last.
• Participate in code reviews, design discussions, and whiteboard sessions.
• Contribute to the core development process in a zero-to-one environment where every line of code matters.

IDEAL CANDIDATE PROFILE:

• Educational Background: No formal education experience required. We prefer candidates who have a strong background in computer science, software engineering, or related fields.
• Strong backend fundamentals — you’ve built and shipped backend services, and you’re fluent in Python, Go, or TypeScript.
• Familiarity with systems-level thinking, API design, database schemas, and distributed systems.
• You’ve completed personal projects, coursework, or open-source contributions that show serious initiative.
• You’re self-directed, detail-oriented, and thrive in fast-paced, ambiguous environments.
• Comfortable working in-office, 3-5 days a week in our NYC Flatiron location.
• Experience with Docker, Postgres, or Redis is a plus.

This can be a part time or a full time role (20-40 hours / week). Candidates must be able to attend standup meetings at 10am EST and be available during the following working hours.

WHY YOU SHOULD JOIN US:

• Innovative Environment: Be at the forefront of financial innovation at a company integrating advanced quantitative techniques with traditional financial models.
• Expert Team: Collaborate with some of the brightest minds in the industry in an environment that values bold ideas and radical solutions to complex problems.
• Professional Growth: Thrive in a vibrant company culture that promotes career development, continuous learning, and intense growth.
• Cutting-Edge Projects: Work on transformative projects that directly impact the future of financial technology.
• Compensation: Equity-only compensation, with an opportunity to convert to paid roles. In-person perks for NYC-based employees include daily free lunch and weekly company bonding events.
