This is a high-ownership role with meaningful autonomy. You’ll operate in a product-ambiguous environment, help define what “great” looks like, and partner closely with design, stakeholders, and leadership as the platform takes its next step forward.

RESPONSIBILITIES:

Design, build, and maintain backend services and APIs that support enterprise use cases and external integrations

Collaborate closely with design, analytics, and engineering partners to translate ambiguous product needs into scalable technical solutions

Define and influence technical direction, system architecture, and implementation standards for the Enterprise platform

Build systems with a strong emphasis on security, privacy, reliability, and correctness, appropriate for enterprise customers

Develop and maintain observability, monitoring, and operational practices to ensure system stability

Consistently deliver high-quality, well-tested code following best practices in software design and development

Help establish engineering foundations that scale, including documentation, patterns, and mentorship as the team grows

QUALIFICATIONS:

4+ years of professional software engineering experience, with a strong foundation in backend development

Experience building and owning production backend systems and RESTful APIs (Java preferred)

Familiarity with authentication, authorization, and identity or account management concepts

Experience working with relational databases such as PostgreSQL

Experience designing and operating services in cloud environments (AWS)

Comfort working across the stack, including contributing to web applications leveraging AI tools (e.g., React), even if backend is your primary strength

Strong system design skills, with experience building scalable, reliable, and maintainable software

Ability to operate effectively in fast-paced, high-ambiguity environments with minimal product process

Strong independent problem-solving skills and a sense of ownership over outcomes

Clear communicator who collaborates well across disciplines and can articulate technical tradeoffs

Builder mindset with interest in helping shape and scale a platform and team over time
