Role Overview
HSF is seeking a highly skilled Full Stack Engineer to join our collaborative and impact-driven team. This role is hands-on and ideal for engineers who thrive in coding-intensive environments and are excited to contribute to both new feature development and the maintenance of existing platforms.

Engineers will design, develop, test, and implement robust software solutions while working closely with cross-functional teams to bring ideas to life. This is a unique opportunity to work on meaningful projects in a mission-oriented setting, with the potential to help shape commercial-ready products in the future.

Key Responsibilities
• Develop, test, and implement software applications with a focus on hands-on coding
• Maintain and enhance existing platforms, including ticket support and bug resolution
• Collaborate with internal teams to translate requirements into scalable solutions
• Participate in design discussions and interdepartmental meetings to drive feature development

Typical Day:
• Understanding requirements and translating them into technical solutions
• Writing and reviewing code
• Participating in team meetings and cross-functional collaboration
• Balancing approximately 80% new feature development / 20% platform support

First 90 Days Contributions:
• Gain a full understanding of the organization’s existing platforms and architecture
• Begin contributing to new feature development for key initiatives
• Take ownership of both ongoing support tasks and forward-looking development projects

Required Technical Skills
• JavaScript
• React.js
• Node.js
• AWS Lambdas
• Next.js
• RDS Postgres
• MySQL
• NoSQL
• Redis
• SQS
• CloudFormation

Nice to Have:
• Python (familiarity is valuable, not required, as our new data stack will leverage Python)

Candidate Profile
• 5–10 years of professional experience in software engineering (ideal 8+ years)
• Bachelor’s degree in Computer Science, Electrical Engineering, or a related field (Master’s degree a plus)
• Experience in web technology is essential; industry background is flexible
• Comfortable in both startup and structured environments
• Motivated by mission-driven work and contributing to the nonprofit sector
• Strong foundational knowledge – not just self-taught coding experience

Dealbreakers:

• Must be onsite in El Segundo as required (hybrid policy from 2026)
• HSF will operate fully remote throughout 2025, with occasional in-office attendance as needed. Beginning in 2026, HSF will transition to a hybrid model, requiring all staff to be onsite three days per week and remote two days per week.
• Looking for candidates invested in both the work and the mission context

Growth & Opportunity
• Start as an individual contributor with deep technical focus
• Opportunity to contribute to white-label commercial product development and work on projects with future commercialization potential

Team Culture
• Highly dedicated, collaborative, and technically strong
• Focused and heads-down when building, but energized by shared goals
• Vibrant environment that values impact and innovation over typical tech culture
