What is a back end developer?

A Back End Developer is a programmer who specializes in building and maintaining the server-side logic, databases, and application functionality that power websites and web applications. Unlike front end developers, who focus on the visual and interactive elements users see, back end developers work behind the scenes to ensure data is stored, processed, and delivered correctly. They typically use programming languages like Python, Java, Ruby, or PHP, and interact with databases such as MySQL or MongoDB. Their work is crucial for making sure applications run smoothly, securely, and efficiently.

What is a back end developer?

A back end developer is a computer science professional who specializes in functionality that takes place on the server side or backend. As a back end developer, you write code to create software that solves a business need. Your responsibilities are to research the needs of either your employer, or a particular industry, find a problem, and create a software solution. A back end developer differs from a traditional web developer, or front end developer, in that back-end software may not have a user interface or even have exposure to the web.

What are the key skills and qualifications needed to thrive as a back end developer?

To thrive as a Back End Developer, you need strong programming skills in languages like Java, Python, or Node.js, along with a solid understanding of databases and API design, typically supported by a degree in computer science or related experience. Familiarity with frameworks such as Spring or Django, version control systems like Git, and cloud platforms (e.g., AWS or Azure) is often required, with certifications in these areas considered beneficial. Problem-solving, effective communication, and teamwork are crucial soft skills that help developers collaborate and address complex technical challenges. These competencies are vital for building reliable, scalable systems that support front-end applications and ensure robust product performance.

What are some common challenges back end developers face when integrating with front-end teams?

Back End Developers often encounter challenges when aligning data structures and APIs with front-end requirements, especially as user interface needs evolve rapidly during development. Effective communication and regular collaboration with front-end developers are essential to ensure that endpoints, data formats, and error handling are well-coordinated. Additionally, maintaining consistent documentation and using tools like Swagger or Postman can help streamline integration and reduce misunderstandings between teams.

What is the difference between Back End Developer vs Front End Developer?

Common CertificationsCertified Web Developer, AWS Certified DeveloperCertified Front End Developer, UI/UX certifications

Back End Developers focus on server-side logic, databases, and APIs, ensuring the website's functionality behind the scenes. Front End Developers work on the visual and interactive aspects users see and interact with. Both roles are essential in web development, often collaborating to create seamless digital experiences.

Is back end developer in demand?

Back end developers are in high demand due to the growth of web applications and digital services. Skills in programming languages like Python, Java, or Node.js, along with knowledge of databases and APIs, are highly sought after by employers across various industries.

Loft Orbital is looking for a Backend Engineer to join our Oort team. Oort is our central web platform-a unified environment that consolidates all infrastructure data and tools, empowering Loft to streamline, integrate, and manage the entire mission lifecycle with unprecedented efficiency and transparency. Oort bridges the gap between diverse mission phases, operational teams, and business processes by centralizing essential information and workflows, establishing a standard for space mission execution at scale.
About this role:
  • Build, and operate features across backend services that collect, manage, and surface critical infrastructure data for the full Loft mission lifecycle.
  • Design and implement APIs and integrations that connect tooling and data across teams and systems.
  • Partner with program management, satellite engineering, operations, and business stakeholders to analyze and understand mission design, program, and business processes-and translate them into intuitive, reliable software.
  • Apply a product mindset across the stack: seek user feedback, identify friction in both backend workflows and UI/UX, and deliver solutions that meaningfully reduce complexity for the people and teams building and operating space infrastructure.

Must Haves:
  • Demonstrated proficiency in Python for backend engineering.
  • Practical experience using Docker for containerization and deployment in scalable environments.
  • Experience in backend architecture, encompassing API design and robust database interactions.
  • You have hands-on experience building, operating, or integrating technologies for space missions and a passion for making complex, multi-team technical endeavors more efficient and standardized.
  • You thrive on dissecting intricate business and technical processes, mapping them end-to-end-highlighting friction points and opportunities for unique solutions.
  • You excel in team environments, communicate complex ideas with clarity, and advocate for seamless collaboration between engineering, operations, and business functions.
  • You are a proactive problem solver and a respectful challenger of assumptions, comfortable owning features from design through production operations.
  • Fluency in English.

Nice to Haves:
  • Experience in the design, modeling, or analysis of space missions, with an understanding of mission lifecycle complexities.
  • Proficiency with Django and GraphQL, and familiarity with modern cloud infrastructure platforms (e.g., Google Cloud Platform/AWS, Kubernetes).
  • Familiarity with testing tools across the stack (e.g., PyTest, Jest, React Testing Library, Playwright/Cypress) and strong CI/CD practices.

Some of Our Awesome Benefits:
  • 100% company-paid medical, dental, and vision insurance option for employees and dependents
  • Flexible Spending (FSA) and Health Savings (HSA) Accounts offered with an employer contribution to the HSA
  • 100% employer paid Life, AD&D, Short-Term, and Long-Term Disability insurance
  • Flexible Time Off policy for vacation and sick leave, and 12 paid holidays
  • 401(k) plan and equity options
  • Daily catered lunches and snacks in office
  • International exposure to our team in France
  • Fully paid parental leave; 14 weeks for birthing parent and 10 weeks for non-birthing parent
  • Carrot Fertility provides comprehensive, inclusive fertility healthcare and family-forming benefits with financial support
  • Off-sites and many social events and celebrations
  • Relocation assistance when applicable

$140,000 - $190,000 a year
State law requires us to tell you the base compensation range for this role, which is $140,000- $190,000 per year. This is determined by your education, experience, knowledge, skills, and abilities. The salary range for this role is intentionally wide as we evaluate individuals based on their unique experience and abilities to fit our needs. Most importantly, we are excited to meet you, and see if you are a great fit for our team. What we can't quantify for you are the exciting challenges, supportive team, and amazing culture we enjoy.
*Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Loft, we value respectful debate and people who aren't afraid to challenge assumptions. We strongly encourage you to apply, even if you don't check all the boxes.
Who We Are
Loft: Space Made Simple.
Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit.
We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 30 missions flown, Loft's flight heritage and proven technologies enable customers to focus on their mission objectives.
With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure.
As an international company your resume will be reviewed by people across our offices so please attach a copy in English.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
