The Principal Engineer at WISEcode will design and oversee complex systems, enhance team capabilities, and integrate AI solutions across the platform, while mentoring senior engineers and shaping engineering culture.
At WISEcode, we're a well-funded, dynamic startup on a mission to transform how the world understands food. WISEcode makes personalized nutrition a reality based on facts — what truly is in our food — and marries this data with your preferences. Driven by AI and the world’s most advanced food and nutrition database, WISEcode embraces the truth that we are all different: different needs, objectives, biology, and preferences. No one should be at the mercy of market spin or “expert” opinion. Everyone deserves the clarity required to make the best decisions for themselves.We are building what does not yet exist: a platform that codifies food transparency, decodes ingredients, and exposes the hidden realities of packaged food. Our products combine deep data engineering, modern AI, and powerful user experiences to bring transparency to millions of consumers.
The Opportunity
WISEcode doesn’t hire for incremental impact — we hire for forcemultipliers. Our Principal Engineers are restless builders who transform complexity into clarity, elevate every team they touch, and create architecture that accelerates the entire company. These are strategic technologists who see systems where others see fragments, who bring long-term thinking into every decision, and who translate bold ideas into elegant, scalable solutions.
About the Role
The Principal Engineer (PE) is WISEcode’s highest-impact individual-contributor role — a technical leader who combines deep hands-on engineering with architectural ownership across major parts of the platform. PEs write excellent code, but also define system boundaries, long-term technical direction, and engineering standards that influence the entire organization.
A WISEcode PE is both strategist and builder. You will:
● Translate product ideas, data models, and company vision into durable architectures.
● Jumpstart high-complexity features or systems end-to-end and hand them off once patterns are established.
● Guide teams through decisions on reliability, performance, schema evolution, observability, AI integration, and scale.
● Influence without authority — shaping engineering culture, mentoring senior engineers, and raising the organizational bar.
PEs at WISEcode operate as a flexible, high-impact bench. You may embed temporarily into a product team to help them accelerate a difficult initiative, unblock architectural issues, or deliver a full-stack vertical slice (UI → API → DB/Lakehouse → infrastructure). You’ll then step out, leaving behind a coherent design, patterns the team can extend, and clearer technical direction than before.
Because of their breadth, PEs typically work closely with the CTO and maintain visibility across products, data systems, and infrastructure. Your success is measured not by a single team’s velocity, but by the health, performance, and agility of the entire WISEcode ecosystem.
How Principal Engineers Operate at WISEcode
Systems thinkers with depth. PEs bring T-shaped skills: deep expertise in multiple domains (e.g., .NET architecture, Postgres/Lakehouse design, distributed systems, AI integration) and broad understanding across UX, product strategy, data modeling, cloud infrastructure, and developer experience.
Architects who execute. You can design a new ingestion pipeline, tune a Postgres query plan, implement a Blazor UI, and architect a multi-service feature — and know how these pieces must evolve over time.
Product-savvy technologists. PEs help shape product direction, not just implement requirements. You anticipate what’s possible, clarify ambiguity, and often write the first version of a spec when needed.
Pragmatic long-term thinkers. You balance delivery speed with architectural integrity. You know where to take shortcuts — and where not to.
Multipliers. You leave teams stronger: cleaner abstractions, clearer documentation, higher engineering maturity, and faster future delivery.
AI Skills & Leadership
WISEcode is an AI-native company. Every engineer is expected to use AI well, but PEs set the tone. You’ll:
● Integrate LLMs and ML components into product workflows where appropriate.
● Understand model behavior enough to guide data quality, explainability, and responsible use.
● Use AI-assisted development to accelerate your own work and teach others how to do the same.
● Advocate for intelligent, data-driven design across ingestion, features, and UX.
AI is not a bolt-on at WISEcode — it is a horizontal capability. PEs ensure it is thoughtfully embedded in the architecture and product surface area.
Key Responsibilities
● Own architecture for major systems across backend, database/lakehouse, and application layers.
● Lead solution design for high-complexity initiatives and deliver production-ready implementations when needed.
● Define patterns, abstractions, and technical standards that increase velocity and consistency.
● Unblock teams by diagnosing issues across full-stack boundaries (Blazor → API → Postgres → data pipelines).
● Guide schema evolution, performance optimization, reliability engineering, and security considerations.
● Mentor senior engineers and elevate engineering culture through clarity, documentation, and example.
● Partner closely with product, design, CTO, data, and AI/ML teams to shape roadmap and feasibility.
● Apply AI/ML concepts to improve automation, personalization, data quality, and developer experience.
Required Qualifications
● BSCS or equivalent engineering degree
● 12+ years of strong professional development experience
● Extensive hands-on full-stack engineering experience with .NET and ASP.NET
● Strong ASP.NET Blazor UI experience and genuine enthusiasm for front-end craftsmanship
● Deep expertise with Postgres, database performance tuning, schema design, and ORMs (especially EF Core)
● Proven ability to design, scale, and evolve enterprise-grade systems and distributed architectures
● Track record of technical leadership, mentoring, and cross-team influence
● Ability to operate independently, set direction, and drive execution in ambiguous contexts
● Broad systems thinking with depth in multiple technical domains
● Familiarity with AI/ML concepts and ability to apply them responsibly in product development
● Startup mindset — adaptability, urgency, pragmatism, and comfort shifting between strategy and hands-on execution
Why Join WISEcode
● Build foundational systems for one of the most ambitious food-tech and AI platforms in the world.
● Work directly with the founder and CTO in a fast-moving, mission-driven environment.
● Shape the architecture, culture, and impact of a category-defining company.
● Competitive compensation, benefits, and opportunities for rapid growth and leadership.

Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.
Key Facts About Los Angeles Tech
- Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
