What is a junior full stack developer?

A Junior Full Stack Developer is an entry-level software professional who works on both the front-end and back-end parts of web applications. They are skilled in basic programming languages and frameworks needed for creating user interfaces as well as handling server-side logic and databases. Typically, juniors work under the guidance of more experienced developers, assisting with coding, debugging, and testing tasks while gradually building their expertise. Their role often involves learning and adapting to new technologies as they gain experience in the field.

What are the key skills and qualifications needed to thrive as a junior full stack developer?

To thrive as a Junior Full Stack Developer, you need a solid understanding of both front-end (HTML, CSS, JavaScript) and back-end (Node.js, Python, Java, or similar) programming, typically supported by a relevant degree or coding bootcamp experience. Familiarity with version control systems like Git, databases (SQL/NoSQL), and frameworks such as React or Express is commonly expected. Strong problem-solving abilities, teamwork, and effective communication are standout soft skills in this role. These skills and qualities ensure you can contribute effectively to diverse projects, adapt to evolving technologies, and collaborate within development teams.

How do junior full stack developers typically balance learning new technologies with meeting project deadlines?

As a Junior Full Stack Developer, you’ll often juggle learning new frameworks or languages while contributing to active projects. Many teams support this by pairing juniors with more experienced developers, offering code reviews, and allocating time for professional development within sprint cycles. While deadlines are important, managers usually recognize the learning curve and provide guidance to help you prioritize tasks and grow your skills without being overwhelmed. Open communication with your team about your progress and challenges is key to maintaining this balance.

Job description

You'll build the systems that move money. Real-time dashboards, lead routing engines, client-facing reporting tools, and high-throughput data pipelines processing millions of events daily. Every feature you ship has a direct line to revenue. This isn't a role where your work disappears into a backlog — you'll see the P&L impact of what you build within days of deploying it.

Your day-to-day responsibilities in this role.

  • Build and maintain full-stack applications (Next.js, React, Node.js) that power campaign management, lead routing, and real-time analytics
  • Architect APIs and data pipelines that handle millions of daily events without breaking a sweat
  • Work directly with marketing and data teams to turn business problems into shipped software
  • Lead code reviews, set engineering standards, and help junior engineers level up
  • Own features end-to-end: scoping, building, deploying, monitoring, and iterating based on live performance data
  • Build internal tooling that makes media buyers faster and campaigns more profitable
  • Write tests that actually catch things (unit, integration, and e2e)
  • Participate in on-call rotations and incident response for production systems
  • Evaluate new technologies based on whether they make us faster, not whether they're trending on Hacker News
What We’re Looking For

The skills and experience we consider essential.

  • 5+ years shipping production software in a full‑stack role
  • Deep fluency in TypeScript, React, and Node.js
  • Solid experience with PostgreSQL, Redis, or similar database systems
  • Working knowledge of cloud infrastructure (AWS or GCP) and how to keep it from costing a fortune
  • Track record of building systems that actually scaled, not just systems designed to
  • Comfortable with CI/CD pipelines, Docker, and infrastructure‑as‑code
  • Can explain technical tradeoffs to non‑technical people without condescending or hand‑wav­ing
  • Thrives in ambiguity. You can take a vague business problem and come back with a clear technical plan
Nice to Have

Bonus points — not required, but they’ll help you hit the ground running.

  • Experience in performance marketing, ad‑tech, or lead generation (you’ll learn fast either way)
  • Familiarity with real‑time data streaming (Kafka, Kinesis)
  • Background in ML/AI integration or data engineering
  • Experience with serverless architectures (Lambda, Edge Functions)
  • Open‑source contributions or a public portfolio we can look at
About the Team

Six engineers own the entire product lifecycle, from whiteboard to production monitoring. We ship weekly, keep meetings short, and choose pragmatic solutions over elegant abstractions. The team works directly with media buyers and data science to build tools that give us a measurable edge over every other acquisition platform in the market.

Everything you need to do your best work.

Competitive salary + annual performance bonus

Health insurance

Generous PTO + company holidays
