Full-Stack Python Engineer

Job Description

Position Name: Full-Stack Python Engineer 

Location: Lincoln, MA, San Francisco or Remote 

Employment Type: Full-time

Citizenship: US Citizens only

Notes: Direct Hire. No third-party assistance is approved for this role.

About The Job: At Jaxon, we are on a mission to make AI trustworthy. The adoption of large language models (LLMs) in corporate settings is hindered by the “hallucination problem,” where AI models produce inaccurate or entirely fabricated responses. For regulated industries and high-risk applications, this issue is preventing LLM use altogether. 

As a Full-Stack Python Engineer at Jaxon, you will play a key role in building the next generation of applications that are powered by our cutting-edge AI platform. You will be responsible for some frontend, but will be interfacing with backend systems, creating a seamless user experience tailored for DSAIL users. This includes designing and implementing intuitive, responsive applications using modern frontend technologies like Dash, and integrating them with a Python backend and RESTful APIs that connect to Jaxon's services.

In this role, you will shape the design and technical direction of the platform, propose and implement best-in-class technologies, and drive decisions that impact user satisfaction and product scalability. You will ensure that our products deliver high performance, scalability, and a fluid user experience, ultimately helping engineers and data scientists perform complex tasks like model deployment, evaluation, and visualization with ease.

The basics of this role require the ability to:

• Collaborate Across Teams: Work with cross-functional teams to integrate ML models into our existing systems and workflows, enhancing product capabilities.

• Demonstrate Technical Proficiency: Demonstrate solid frontend development experience, particularly with data-intensive applications. Be comfortable showing leadership on frontend design best practices. 

• Understand Machine Learning Models: Be familiar with machine learning models, particularly how they work and are used, so you can understand DSAIL and what we do.

Soft Skills:

• Able to context switch as needed

• Able to compartmentalize different projects with different goals

• Able to communicate clearly and precisely - not just abstractions and "lines-and-boxes"

Specific Technologies:

• Python

• Building and deploying component libraries

• Web APIs and how to integrate with them

• Familiarity with Python Data Science Stack - NumPy, Pandas, Scikit Learn, various deep learning packages

• Knowledge in AI/ML techniques is a major plus

Nice-To-Haves:

• Experience with the Dash framework or a willingness to learn if not already proficient

• Comfortable with frontend state management libraries like Redux and MobX

• Bonus points for knowledge of React or a similar frontend frameworks

• Experience with using Figma as part of a design and implementation workflow

• Familiarity with TypeScript and JavaScript

• Familiarity with CSS and SASS or SCSS

About Jaxon: Jaxon is a leading provider of machine learning and artificial intelligence solutions. We are committed to helping our customers solve complex problems with AI. Our products and services are used by businesses of all sizes, from startups to Fortune 500 companies.

What Makes Jaxon Different?

• Human First: Our leaders get it — life happens. Whether it’s flexible working hours or understanding the need for a mental health day, we prioritize your well-being. Our CEO recognizes that happy people do the best work and he backs that up with an empathetically led culture – and I’m not just saying that because he’s going to read this post. 

• Laid-Back Culture: We know that the best work comes from a place of comfort and authenticity. At Jaxon, you’re encouraged to be yourself, dress casually, and embrace your quirky side. It’s just one of the benefits of being an early-stage, high-growth startup.

• Tech Lover's Dream: From hackathons to tech talks with industry leaders, we fuel our passion for innovation with constant learning and development opportunities.

• Grunt Work to Grand Projects: Every task you tackle, big or small, matters. You think I’m writing job descriptions for fun? Sometimes things need to get done and it’s an all hands on deck situation to get them to the finish line. We're looking for team players who understand that achieving groundbreaking AI innovations sometimes involves rolling up your sleeves to tackle the essential, yet less glamorous tasks.

• ​​Excited about the prospect of free snacks, massages, and a hot tub at the office? You might have to keep looking, as we're a fully remote team. However, if you ever feel the need to switch up your work environment, you’re always welcome at our office space in Lincoln, Massachusetts—includes a dartboard for slow afternoons.

Added Perks:

• Unlimited PTO: (seriously!)

• Comprehensive benefits: Health, dental, and vision insurance

• Competitive Salary: We provide competitive compensation packages commensurate with experience

• Stock Options: All compensation plans include stock options - join now and benefit from future acquisitions

• Holidays Off: ALL federal holidays are paid time off

Qualifications

About You: You're the type of person who's naturally driven—not necessarily because you built a rocket in your backyard as a kid, but because you have a genuine curiosity about the world of technology. In your spare time, you might find yourself deep-diving into technology subreddits, following the latest industry trends, or exploring which companies are innovating and how. Your passion isn't just about staying informed; it's about thinking how you can take these emerging concepts and scale them up, make them faster, or more impactful. At Jaxon, we're looking for someone who sees a baseline and instinctively wants to build beyond it. If you’re ready to take what exists and make it extraordinary, you’ll fit right in.

The engineering team at Jaxon warned me that all engineers hate when job descriptions specify bullet lists of X years of experience in technology Y such that time_exists(Y) < X. With that being said, there are no hard tech requirements, but experience with the python ML ecosystem and with LLMs is expected. Additionally:

• You’re going to need proven expertise in building ML applications. 

• Proficient Python including demonstrable experience with libraries relevant to data manipulation. 

• Ideally some experience with machine learning, in particular NLP applications.

• You are primarily in a development role, but are comfortable being customer-facing when needed.

• Active security clearance is a bonus.

• 2 or more years equivalent professional or military experience.

• All candidates must derive backpropagation on a whiteboard.  (Just kidding! Made you blink.).

We are looking for somebody who thrives in an environment where day-to-day priorities and tasks may rapidly change. The role is not a fit if you value "business as usual".

We value team members who are bold enough to pitch creative ideas, even if they're still rough around the edges or might not make the final cut.

Education and Length of Experience

Preferably applicants will have a bachelor's degree in Computer Science or similar, however at Jaxon, we value skills and dedication over degrees. We strongly encourage people without degrees to apply if you have at least 5 years of experience.

Jaxon is proud to be an equal opportunity workplace and is an affirmative action employer. We are committed to equal employment opportunities regardless of race, color, ancestry, religion, sex, sexual orientation, age, marital status, disability, or Veteran status.
