Required SkillsProgramming languages like Java, Python, SQLHTML, CSS, JavaScript, frameworks like React or Angular
Work EnvironmentServer infrastructure, cloud servicesDesign tools, browser testing
Common UsageBuilding and maintaining backend systemsCreating engaging user interfaces

Backend Software Developers focus on server-side development, managing databases, and APIs, while Frontend Software Developers work on the visual and interactive aspects of websites and applications. Both roles are essential in full-stack development but differ in their technical skills and daily tasks.

What does a Backend Software Developer do?

A Backend Software Developer is responsible for building and maintaining the server-side logic, databases, and application programming interfaces (APIs) that power web and mobile applications. They ensure that data is properly stored, secured, and retrieved, and that the backend communicates effectively with the frontend or user-facing side. Backend developers often work with programming languages like Java, Python, Ruby, or Node.js, and use frameworks and tools to optimize application performance and scalability. Their work is crucial for ensuring that applications run smoothly, handle user requests efficiently, and remain secure.

What are the key skills and qualifications needed to thrive as a Backend Software Developer, and why are they important?

To thrive as a Backend Software Developer, you need strong programming skills (such as Java, Python, or Node.js), a solid understanding of algorithms, data structures, and database management, often supported by a degree in computer science or a related field. Familiarity with frameworks (like Spring or Django), RESTful APIs, version control systems (such as Git), and cloud platforms is typically expected, along with relevant certifications being beneficial. Problem-solving abilities, attention to detail, and effective communication are the soft skills that set outstanding backend developers apart. These skills and qualities are crucial for building scalable, reliable, and secure server-side applications that meet business and user needs.

What are some common challenges faced by Backend Software Developers when integrating new technologies into existing systems?

Backend Software Developers often encounter challenges when integrating new technologies, such as ensuring compatibility with legacy systems, maintaining data integrity during migrations, and minimizing downtime for end users. They must also carefully manage dependencies and address potential security vulnerabilities introduced by new components. Collaboration with DevOps, frontend teams, and QA is crucial to ensure smooth deployment and comprehensive testing throughout the integration process.

Job description

Who we are
In the past, to be a successful restaurateur, you simply had to have a passion for food and a passion for people - but to succeed as a digital restaurateur you also need to have a passion for technology. We believe in the joy of serving others, and that's why we created Otter - to help restaurateurs succeed in online food delivery. Restaurants around the world, both large and small, including Chick-fil-A, Ben & Jerry's, KFC, and Eataly trust our software to power their delivery business. We increase sales, reduce order issues, and decrease delivery headaches.
What you'll do
As a Software Engineer on the Otter Marketing/Boost team, you'll build the AI-powered platform that puts restaurant growth on autopilot, automating marketing for each storefront across delivery platforms. Your code will turn a merchant's budget and goals into real orders.
  • Build backend services for campaign management, budgeting, and a multi-channel pipeline that deploys campaigns and keeps them in sync across delivery platforms.
  • Develop the AI-driven Boost engine that analyzes each store, picks the best marketing for its goal, executes within budget, and recalibrates automatically.
  • Build durable workflows for campaign orchestration, budget enforcement, and auto-pause guardrails that run correctly, every day, at scale.
  • Integrate with third-party delivery platforms and handle the realities of external APIs: partial failures, retries, and reconciliation.
  • Own your services end-to-end: develop, instrument, debug, and improve reliability and performance.

What we're looking for
We value diversity of experience and are looking for engineers excited to own complex, high-impact systems. We look for a strong sense of ownership, people ready to take their work from idea to production and take responsibility for outcomes.
Basic Qualifications
  • Proficiency in a general-purpose backend language (e.g., Java, Go, or Python).
  • Solid foundation in distributed systems, microservices, and API design (gRPC and/or REST).
  • Experience with databases (e.g., PostgreSQL, CockroachDB) and writing performant queries.
  • Strong debugging skills and an instinct for reliability in systems that integrate with unpredictable third parties.
  • Experience operating services in production, and a collaborative, product-minded approach.

Nice to Have
  • Workflow orchestration (e.g., Temporal, Cadence) or event-driven architectures (Kafka).
  • Large-scale data and analytics tooling (Trino, Flink, Iceberg, or equivalent).
  • ML systems in production, predictions, ranking, or optimization, or a strong interest in them.
  • Cloud platforms (Azure, AWS, GCP) and containers (Docker, Kubernetes)

Why join us
  • Demand for online food delivery is growing really fast! In the last 5 years, just in the US, the overall market has expanded 10X from $10B to $100B, and could expand to $500bn- $1T by 2030.
  • Changing the restaurant industry: You'll be part of a team that helps restaurants succeed in online food delivery.
  • Collaborative environment: You will receive support and guidance from experienced colleagues and managers, helping you to learn, grow and achieve your goals, and you'll work closely with other teams to ensure our customer's success.

What else you need to know
This role is based in our Seattle office location. As a company driven by innovation and continuous change, close collaboration is essential. We're constantly reimagining our industry, creating new products, and refining our processes, and we do our best work together. That's why all of our office-based teams work onsite, five days a week.
The base salary range for this role is $167,000 - $230,000 per year.
Actual compensation will be determined on an individual basis and may vary depending on experience, skills, and qualifications.
Base salary is just one part of your total rewards package. You may also be eligible for equity awards and an annual performance-based bonus.
Benefits Summary (USA Full-Time Exempt Employees):
  • Medical, dental, and vision insurance (multiple plans, incl. HSA options).
  • Company-paid life and disability insurance (short- and long-term).
  • Voluntary insurance: accident, critical illness, hospital indemnity.
  • Optional supplemental life insurance for self, spouse, and children.
  • Pet insurance discount.
  • 401(k).
  • Health Savings Account (HSA)
  • Flexible Spending Accounts (Healthcare, Dependent Care, Commuter)
  • Time Off policies:
    • Discretionary vacation days
    • 8 paid holidays per year
    • Paid sick time
    • Paid Bereavement leave
    • Paid Parental Leave

Benefits are subject to change at the company's discretion.
Atoms accepts applications on an ongoing basis.
