Product Engineer (Staff/Principal) New York
Fifth Dimension AI, New York, NY, United States
About You
You're an expert software engineer who thinks in terms of user outcomes, not just code. You don't just ship features—you understand the problem space deeply, make sharp product calls, and build solutions that customers didn't know they needed until they can't live without them.
You've honed your craft through years of practice across the full stack, from performant backends and well-designed APIs to responsive, polished frontends. You have strong product intuition—you know how to talk to customers, read between the lines of a feature request, and make pragmatic trade-offs between scope, speed, and quality.
You're proficient with AI coding assistance tools like Claude Code, leveraging them to accelerate development and focus on higher-level product and architectural challenges. You understand that modern engineering means effectively collaborating with AI to maximise your productivity and creative potential.
Details don't escape you. You take pride in the end-to-end user experience—from the API contract to the loading state to the edge case that only one customer hits. As someone who thrives in fast-paced environments, you adapt quickly and mentor other engineers while collaborating effectively with commercial teams and customers.
You're passionate about your personal growth and see each complex problem as an opportunity to expand your capabilities. You actively seek challenges that push the boundaries of what's possible and value environments where you can both contribute your expertise and continue to evolve as an engineer.
Your Impact
Reporting to our CTO Chen, you'll own and shape core product areas end-to-end—from discovery and design through to architecture, implementation, deployment, and customer adoption. Working closely with our skilled engineering team and commercial stakeholders, you'll combine deep technical ability with strong product sense to build capabilities that deliver tangible value to enterprise customers and drive the business forward.
Day to Day, You Will
Think like a Product Manager+ : Own core product areas while balancing technical excellence with business impact—you don't wait for a spec, you help write it
Own end-to-end delivery
of complex features from discovery and definition through to production deployment and customer adoption
Talk to customers
regularly—understanding their workflows, pain points, and unarticulated needs to inform what you build
Collaborate with product, design, and commercial teams
to shape the roadmap and translate customer insight into robust technical solutions
Leverage AI coding tools
like Claude Code to accelerate development workflows
Lead development of the systems that underpin our platform:
Scalable APIs and backend services that power document processing, data extraction, and agentic workflows
Reliable streaming and event-driven architectures for real-time user experiences
Frontend experiences that make powerful AI capabilities intuitive and accessible
Integrations with enterprise systems and third-party platforms
Implement data privacy and security by design
Champion engineering best practices : testing, observability, CI/CD, and infrastructure-as-code
Mentor other engineers
and help establish engineering and product-thinking best practices
Invest in your own growth
by taking on ambitious technical challenges and expanding your expertise
Apply our engineering philosophy : intellectual honesty, effective time management, clear communication, and innovation
Our Values and Engineering Culture
At 5D, we embody three core principles:
Own it, Ship it, and Don't be boring .
Our engineering team values:
Product-Minded Engineering : Understanding the "why" behind features and using technical expertise to inform product decisions
Intellectual Honesty : Backing discussions with data and acknowledging knowledge gaps
Effective Time Management : Setting clear timebox and abandoning approaches that aren't working
Clear Communication : Writing self-documenting code and providing detailed explanations
Innovation Mindset : Forming well-reasoned opinions backed by data and continuously learning
Personal Growth : Supporting your development through challenging work and opportunities to expand your expertise
What We're Looking For
Experience in high-growth startups or fast-paced tech environments
Track record building software in organizations with excellent engineering practices
History of owning end-to-end product development, from discovery and definition to delivery and customer adoption
Demonstrated product instinct—you've shaped what gets built, not just how it gets built
Strong Python skills with a track record of shipping customer-facing features on critical paths
Experience designing and building high-quality APIs, services, and distributed systems
Solid frontend skills and experience building polished, user-facing applications
Proficiency with AI coding assistance tools (Cursor, GitHub Copilot, Claude Code)
Intellectual curiosity and honesty—digging deep into problems and sharing findings openly
Proven ability to make technical decisions that balance immediate user needs with long-term architecture
Exceptional communication abilities for explaining complex concepts to diverse audiences
Ambition and resilience—we're a seed-stage company tackling ambitious challenges
Commercial awareness—delivering continuous value to customers is essential
Passion for personal growth and continuous learning
Nice to Have (But Not Required)
Experience with cloud infrastructure (GCP, AWS, or Azure) and container orchestration
Past experience in real estate, law, or finance
Background with robust software testing and deployment practices
Experience with component-based system design and microservices
Experience with event-driven architectures and streaming systems
Contributions to open-source projects or broader technical communities
What We Offer You
We're building something extraordinary and we want extraordinary people. Our benefits package goes beyond the standard startup offering—from tailored support for life's challenges (IVF, gender-affirming care, ADHD diagnosis, and more), to meaningful parental leave.
$150,000-300,000 salary per annum + meaningful equity (on a standard vesting schedule)
Other strong employment benefits
