Full-Stack Software Engineer, Frontend

Synonym enables the commercialization and manufacture of bioproducts—accelerating the world’s transition to better, more sustainable materials and products. We believe that products created using biology will represent the next manufacturing revolution, transforming crucial elements of supply chains across multiple sectors and helping to catalyze a sustainable and decarbonized future.

Synonym works as the strategic biomanufacturing partner for companies building these next-generation bioproducts. We help companies chart their roadmaps toward commercialization and profitability by building custom techno-economic analyses (TEA) and carbon emissions estimates. We match companies with contract manufacturers (CMOs) to help companies secure capacity and meet production needs. And we undertake large capital projects, working with companies to develop, finance, construct, and operate dedicated, modular fermentation facilities so they can produce at scale.

If you want to tackle global challenges that will help support a more sustainable future and be part of a team that will be an integral part of the emerging biomanufacturing ecosystem, we'd love to hear from you!

Role Description (Full-Stack Engineer, Frontend)

Synonym is developing the next generation of our Scaler product: a process simulation and techno-economic assessment (TEA) tool for industrial processes. The goal of Scaler is to make the early stages of process engineering 10x faster, helping companies and investors bring new products to market and accelerate industrial decarbonization.

As a full-stack software engineer, you’ll work closely with our lead software engineer to develop Scaler from the ground up. We’re looking for candidates who enjoy taking ideas from 0 to 1, owning key pieces of the codebase, and delivering value to users. As the second hire on our software team, you’ll have the opportunity to contribute across the software stack, shape our product roadmap, and grow with the team.

While this is a full-stack engineering role, it has an immediate UI/UX focus. Ideal candidates should be comfortable leading the development of new frontend features and have demonstrated experience building user-friendly, modern web apps.

Example projects you might work on:

• Building a flexible and intuitive UI/UX for use by chemical engineers

• Building out a React component library to improve code reuse and accelerate UI development

• Adding LLM-powered capabilities to generate suggestions for our chemical engineering team as they use the tool

• Adding new modeling capabilities to our techno-economic engine

• Building out a data pipeline for ingesting relevant data that informs our models

Key Responsibilities

• Lead UI/UX development for Scaler

• Contribute across software stack and play an active role in engineering decisions

• Help shape our product vision and roadmap based on user feedback

• Work closely with the process engineering, platform, and business teams to align product development with internal/external needs

Competencies

Must-have

• Demonstrated experience developing full-stack web applications

• Strong ability in Typescript and React

• High level of ownership and responsibility

• Good communication and collaboration skills, with the ability to work effectively on a remote team.

Nice-to-have

• Experience in the specific frameworks we use: React, Next.js, TailwindCSS (frontend); FastAPI, Postgres, Supabase (backend).

• Early-stage startup experience

• Familiarity with other science and engineering disciplines (e.g., biology, physics, chemistry)

• Good design intuition, and ability to help prototype new ideas in Figma

• Degree in Computer Science or a related field preferred.

Compensation

$120,000-160,000

Other

While fully-remote, Synonym’s team values cohesiveness and in-person collaboration. We have a preference for candidates near our existing team (NYC, SF/Bay Area, Boston) who are open to hybrid work. This role would primarily work with our lead software engineer who is located in Cambridge, MA.

Our team aspires to hire great people and create an environment where we can be happy, feel challenged, and do our best work. It's an exciting time to join Synonym and build that environment from the ground up!

Benefits Include

• Comprehensive medical, dental and vision coverage

• Daily lunch allowance

• Beautiful office in SoHo (NYC), or coworking space (Boston, SF Bay Area)

• Competitive compensation packages, including equity

• Unlimited PTO

• 401(k) 

• Team offsites
