MustardHub

* Please note this position is for Kannact, a company we're involved with, not for MustardHub.

Kannact is a health coaching service dedicated to helping people with chronic conditions. Our platform consists of a CRM that the coaches use, a patient portal, an app that runs the landing pages, and a booking portal. We're a very well established company primarily located in Spain.

This position is for an independent and autonomous middle-level Front End engineer well-versed in TypeScript + React (Next is a nice bonus).

You will:

• Take ownership of various frontend applications (CRM, Patient Portal, Landing Site, Booking App).
• Work independently and figure things out. You won't have to architect any new applications, but you'll need to be supporting the existing ones.
• Eventually, potentially contribute to backend tasks.
• You will work alongside 3 other developers. You will report to the VP Engineering located in Spain and you'll be working primarily Spain hours; every once in a while you'll have to take meetings with our team members in the US.
• Your English is great. You can hold a conversation with a native speaker, or a non-native English speaker.

Our Tech Stack:

• React, React Query (REST APIs)
• SASS, BEM, Prime React
• Next.js is used for our marketing site (both Pages Router and App Router)
• State Management, Forms (React Hook Forms)
• Build Tools/Monorepos (Turborepo awareness is a plus)
• Validation Libraries (Zod awareness is a plus)
• Testing: Experience or willingness to learn Playwright (E2E)
• Interacting with APIs (REST, potentially SDKs like Twilio).
• Understanding of SSR and SSG concepts.
• Experience with Headless CMS (like Sanity.io) is a plus.

We're primarily located in Spain with a few team members in the US. You'll be primarily working Spain work hours.

MustardHub is a B2B SaaS startup in the employee benefits, rewards & recognition space.

We've built our MVP in 2023, confirmed the hypothesis with several large customers, and are now underway building the v1 from ground-up.

This position is for an experienced, autonomous back-end developer. We're a very small team, led by the two co-founders, with an experienced backend architect/lead developer, 2 FE devs, BA/PM, and a talented designer. 

About You:

- Are an experienced developer who is not afraid to get his/her hands dirty

- You've worked on large B2B or B2C SaaS products

- You can teach me (and everyone else on the team) the right ways of building our back end

- You understand what working in early-stage startups is like

- Your English is good enough to have conversations with patient fluent speakers

- You are EXCITED about being on the ground floor of a startup that changes how companies approach employee rewards & benefits management

- You're already using or are willing to adopt modern AI coding tools like Cursor+Composer with Claude/Gemini/gpt-4.1, and others to increase your output 2-4x.

Our Tech Stack:

- Typescript: React, Nest, GraphQL/Apollo, Postgres. 

We're based in Austin, TX (US) but the development team is expected to be all remote. The other team members are in Ukraine and the rest of Eastern Europe. You're expected to have at least a few hours overlap with the CDT timezone each day.
