What are some unique challenges a part-time Java Developer might face when working at a startup?

As a part-time Java Developer in a startup environment, you may encounter challenges such as shifting priorities, tight deadlines, and the need to quickly adapt to new technologies or tools. Startups often operate with lean teams, so you might be expected to handle a broad range of tasks beyond core Java development, including troubleshooting, deployment, and occasionally assisting with frontend or DevOps work. Effective communication and time management are essential, as you'll need to stay aligned with the team's goals and progress despite working fewer hours. These challenges can also provide valuable learning experiences and opportunities for rapid professional growth.

What are the key skills and qualifications needed to thrive as a Part Time Java Developer at a startup, and why are they important?

To thrive as a Part Time Java Developer at a startup, you need strong Java programming skills, experience with frameworks like Spring or Hibernate, and a foundational understanding of software development principles. Familiarity with version control systems (like Git), cloud platforms, and agile development tools is often expected, alongside a relevant degree or certification. Initiative, adaptability, and effective communication are crucial soft skills for collaborating in a fast-paced, resource-constrained environment. These capabilities are important to efficiently deliver scalable solutions and contribute meaningfully to rapid product iterations typical in startups.

What does a Part Time Java Developer do at a startup?

A Part Time Java Developer at a startup is responsible for designing, coding, and testing Java-based applications on a flexible schedule. They typically work on building new features, fixing bugs, and collaborating closely with other team members to help the startup grow quickly. The role may also involve participating in code reviews, optimizing performance, and adapting quickly to changing project requirements. Since startups often require team members to wear multiple hats, part-time Java Developers might also contribute to other aspects of the development process or learn new technologies as needed.

Job description

Company Description

iFLIP4 is the brand and network for people to care. We're creating the one home for everything related to nonprofits, doing good, and changing the world -- targeted at millennials who overwhelmingly want to do good but don't know how. They can come to the site and learn about causes with articles, videos and games; they can find a nonprofit they love; and they can support it all in one place. The first way they can do that is that for every iFLIP4 product purchased, iFLIP4 donates half of the profits to the charity of their choice.


Pre-launch, we have been featured in the New York Post, and we are also the recipients of the Brown University C.V. Starr Social Entrepreneurship Fellowship.


We have iFLIP4 Ambassadors (campus representatives) on 50+ college and high school campuses in the US, UK, and Canada, and iFLIP4.com has been visited in 140+ countries.

Some of our advisors include a former treasurer of IBM, a media expert who helped launch MTV, a Fulbright winning law professor, and a senior advertising executive in charge of $250 million of ad sales at Yahoo.

Job Description

We want to change the world. We're a team of fast-executing social entrepreneurs on a mission to build the future of social change. You want to change the world? This is your chance!

We are searching for an exceptional mobile app developer to build our business with. You will work closely with our CTO and other members of the Core Team to design and develop world-changing mobile apps for iOS and Android platforms.

We don't want a code monkey; we don't want someone to say yes and implement every feature we ask for. What we want is a partner. Someone to bounce ideas off of, someone with a vision for the future of our company, and someone who has the desire and drive to make it a reality.

We want the best of the best. We've built a team of supremely talented and dedicated individuals, and we want our app developer to be the same.

Qualifications

  1. At least 1-2 years of experience developing mobile applications across their entire life cycle -- concept, design, build, deploy, test, release to app stores and support

  2. Deep technical knowledge of iOS mobile app development, including Objective C

  3. Preferred knowledge of Android development as well, including Java, GIT, Android Studio, RESTful APIs, and know-how of prominent Android guidelines by Google and its official libraries

  4. Knowledge of design guidelines by Google and Apple

  5. Ability to integrate social APIs with apps

  6. Ability to use prototyping and wireframing tools

  7. Preferred: At least one iOS app showcasing your work in the App Store

  8. Must be passionate about quality software and writing clean code

Additional Information

This job requires a commitment of about 20 hours/week and is unpaid to start. After we raise our Angel round of funding, there is the potential for this role to grow into a full-time position with a full salary and vested equity in iFLIP4, assuming the work you do is great! We are located in East Hanover, NJ, and telecommuting is fine with us.

Please send your resume to Team [at] iFLIP4.com. Preference will be given to those who apply earliest.
