Role : Mid-Level Front-end Web Developer -The Visibility Assassin
Most web dev roles have you pushing pixels in the dark. This one hands you the digital front door to a technology that literally sees inside supply chains in real time and you're expected to make the world stop scrolling and start paying attention.
About Our Client:
We don't build logistics software. We build x-ray vision for supply chains. Our patented IIoT hardware and AI SaaS platform give companies continuous, real-time Asset Intelligence: they know where every asset is, what it's doing, and what happens next. No delays. No guesses. No excuses.
We've already made customers rethink everything about how they operate. Now we need the web presence to match: fast, aggressive, designed for people who understand that seeing everything changes everything. If your site doesn't make that obvious in five seconds, you're losing.
About the Role
This isn't "manage the website." As Web Developer you own the digital nervous system of a company that sees what competitors are blind to. The corporate site, the landing page engine, the conversion infrastructure, all of it translates Asset Intelligence into revenue.
You'll take designs and campaign ideas and turn them into a system so tight, so fast, so sharp that non-technical teams can launch pages at startup velocity without breaking a thing. Every pixel you touch either strengthens the story or gets cut.
What You'll Be Doing
- Rebuild the corporate website so viscerally good that landing on it feels like a glimpse into the future of supply chain intelligence, not a slide show
- Build landing page templates that let Marketing move at insane speed without needing your approval every time they want to tell a new story
- Translate designs into code that's so clean, so responsive, so fast that page load times become a selling point, not an apology
- Own conversion like your job depends on it: forms that don't leak, CTAs that don't beg, flows that don't waste visitors
- Work directly with Marketing on messaging that makes Asset Intelligence feel inevitable, not optional
- Partner with Product to build pages that explain what we do in ten seconds, period
- Set up a CMS that lets non-technical teams feel powerful, not terrified
- Plug in analytics and A/B testing so every page proves what works with data, not feelings
- Guard performance and reliability obsessively: if the site slows down, it better be worth it
Who You Are
You're not a Web Developer who tolerates mediocre websites. You're the person who feels physical pain watching slow load times, broken forms, and lazy design. You see a page that doesn't convert and you already know how to fix it.
You move at startup speed and don't ship garbage. You speak design, you understand pipeline, and you know that performance is a feature, not a luxury. You own problems completely and fix them before someone notices they exist. If this doesn't sound like obsession, you're not our person.
You will have
- 3–5 years of hands-on web development shipping real production sites that real people used and actually liked
- HTML, CSS, and JavaScript skills so sharp you don't need Stack Overflow for the basics
- Real experience with React or Vue, chosen intentionally because you understand the tradeoffs
- A track record of building CMS-driven sites and marketing landing pages that moved conversions and pipeline
- Deep understanding of conversion: you know where users drop and how to stop it
- Comfort living in Figma and design systems without hand-holding
- Startup DNA: you move, you own, you don't wait for permission
Nice to have:
- A/B testing experience and the discipline to read results like they matter
- Familiarity with CRM, email, and analytics platforms because integrations shouldn't scare you
- Time spent in environments where "move fast and iterate" isn't corporate speak, it's the default
Why Us
You're not taking a job at a company that treats the website like IT overhead. You're stepping into control of how Asset Intelligence, actual, patented, game-changing technology, gets discovered and understood by the people who need to see it.
Leadership listens when you say something matters. Marketing moves faster because your systems enable speed instead of choking it. You get autonomy, real technical challenges, and the satisfaction of watching conversions spike because the web layer actually helped.
We move fast. We expect sharp. We don't accept mediocre.
The Bottom Line
If you're ready to take the title of Mid-Level Web Developer and own the digital face of a company that sees inside supply chains and won't let the world forget it, this is your seat. You're not here to patch templates. You're here to build the front door that makes Asset Intelligence impossible to ignore.
