Job Description:

Come join a growing, dynamic, and innovative fintech startup that is fast becoming a market leader in Procurement-as-a-Service solutions. Concertiv’s mission is to simplify the decisions that businesses must make. To that end, we’re building a software platform that integrates workflow, contract management, and spend analysis to help our customers buy the best products at the best prices. Our platform empowers users to increase productivity, reduce costs, and gain new insights for strategic business decisions.  For more information visit us at:

We are looking for a Senior Full-Stack Software Engineer to join our A+ engineering team. Our tech stack is modern, well-documented and has very little tech debt (the second-gen platform we're building out right now is a greenfield project). Specific technologies include React, TypeScript, Django, PostgreSQL, and AWS CDK. We’re particularly interested in candidates with a preference for backend engineering, and DevOps experience is a major plus.
Our engineers work closely with end-users as well as the product team to define the vision and direction of the product. As an engineer at Concertiv, you will be challenged to work across the entire stack: everything from writing pixel-perfect frontend components to designing robust database schemas that capture complex real-world challenges in efficient and scalable ways. You will be part of an agile engineering team that brings this offering to global customers and new markets by building, integrating, testing, and continuously deploying new features and products.

Skills and experience:
  • Bachelor's degree in Computer Science or related field (or equivalent work experience).
  • 5+ years of full-time professional software engineering experience.
  • Strong CS fundamentals, including a solid understanding of data structures, algorithms, and concurrency. Understanding of databases, networking, internet security, cloud computing frameworks like Kubernetes and the AWS offerings is a plus.
  • 5+ years of experience with backend frameworks such as Django, Rails, Node + Express, Go + Gin, Spring, etc...
  • 5+ years of experience using relational databases in a production environment (we use PostgreSQL), including schema design, query optimization, and working with object relational mappers (we use Django’s ORM).
  • 3+ years of experience using modern deployment technologies in a production environment. Experience with AWS CDK is a plus.
  • 3+ years of experience with modern frontend technologies such as React, JavaScript, HTML5, and CSS. Experience with TypeScript, React Hooks, Redux Toolkit, and Material UI is a plus.
  • Strong understanding of modern web application design patterns and concepts (SPAs, REST, GraphQL, containerization, testing, etc…).
  • Strong understanding of agile practices and tools.
  • Proven software design skills with the ability to work well in a dynamic, fast-paced environment.
  • Excellent written and verbal communication skills with an effective and efficient communication style.
  • A proven ability to work independently and in a winning team environment.
  • A self-starter possessing an entrepreneurial mindset with a high level of energy, dedication, and integrity.
What will you do:
  • Build, test, and continuously deploy code across the backend and frontend.
  • Research and propose solutions to complex business and engineering challenges.
  • Maintain thorough code coverage by writing high-quality unit, integration, and end-to-end tests.
  • Write exemplary documentation.
  • Work closely with product management to envision and prototype new features for the platform.
Who will love this job:
  • team player: you know when to collaborate and when to execute solo
  • problem solver: you ask the right questions and drive towards solutions with exceptional attention to detail
  • builder: you will set a high bar for engineering practices, contribute to our knowledge base, and bring an entrepreneurial mindset to support our growth
  • Opportunities for Remote-first and in-person positions at our NYC and Boston locations.
  • Competitive compensation with additional upside potential
  • Ground floor opportunity to shape the strategic direction of an industry-disrupting business.
  • Sharp, motivated co-workers in a fun work environment.
  • Generous Health, Dental, Vision Benefits and PTO Plan.
