About the RoleAs a Senior Software Engineer, you will be a core contributor on an engineering team led by our Technical Lead. You'll own significant features end to end, help shape system architecture, and set the bar for code quality across the team. This is a hands-on individual contributor role: you'll spend the majority of your time building, reviewing, and improving high-performing software. While you won't have direct reports, you'll be expected to raise the team's technical level through strong code reviews, thoughtful design input, and informal mentorship of less-experienced engineers.
RequirementsEducation- Bachelor's degree in Computer Science, Software Engineering, Information Technology, or a related technical field (or equivalent combination of education and hands-on practical experience).
Overall Experience- 5+ years of progressive software engineering experience across the full software development life cycle (SDLC).
- Demonstrated ability to operate with a high degree of autonomy: scoping and breaking down complex work, driving features to completion, and unblocking yourself and others.
- Experience mentoring or guiding other engineers through code reviews, pairing, and technical discussion (formal management experience is not required).
Domain Experience- 2+ years of direct experience building, scaling, or maintaining e-commerce platforms, multi-vendor marketplaces, or high-volume transactional SaaS applications.
- Working understanding of domain-specific challenges, such as shopping cart state management, payment gateway integrations, inventory synchronization, and secure user data handling.
- Hands-on experience integrating PunchOut catalogs with third-party procurement and ERP systems (e.g., SAP Ariba, Coupa, Jaggaer, Oracle Procurement), including the end-to-end punchout session and cart round-trip.
Technical Experience- 4+ years of full-stack development experience heavily focused on the JavaScript/TypeScript ecosystem.
- Strong hands-on experience designing and building scalable backend services and RESTful/GraphQL APIs using Node.js and Nest.js.
- Solid experience developing responsive and high-performance frontends using React and Next.js.
- Practical experience with database design and management, including a working knowledge of both NoSQL (MongoDB for dynamic catalogs/profiles) and relational (MySQL for strict financial/order ledgers) databases.
- Familiarity with e-procurement integration standards and protocols - cXML PunchOut (PunchOutSetupRequest/Response, PunchOutOrderMessage) and/or OCI - along with purchase order and invoice document exchange (e.g., cXML OrderRequest, InvoiceDetailRequest).
Preferred Qualifications- Advanced E-commerce Expertise: Prior experience with high-growth e-commerce or multi-vendor marketplace platforms, specifically addressing challenges such as multi-currency transactions, global logistics, or complex vendor payout structures.
- Security & Compliance Awareness: Familiarity with industry-standard compliance frameworks and security protocols, such as SOC 2, NIST, or PCI-DSS, and experience applying these controls within a cloud-native software development lifecycle.
- PunchOut & Procurement Integration Depth: Proven experience building and maintaining PunchOut catalog connections at scale - including Level 1 and Level 2 PunchOut, hosted/CIF catalogs, shared-secret authentication, session handling, and troubleshooting connections across multiple buyer procurement platforms.
Key Performance GoalsHigh-Quality Feature Delivery- Consistently deliver well-tested, high-quality marketplace features on time. Scope your own work accurately within agile sprints and proactively flag and resolve technical roadblocks.
Platform Quality & Stability- Contribute directly to the scalability, security, and reliability of the e-commerce platform (across Node.js, React, MySQL, and MongoDB) by writing maintainable code, upholding code review standards, and minimizing production bugs.
Technical Influence & Mentorship- Help elevate the team's overall technical capability through high-quality code reviews, sound design input, and informal mentorship of fellow engineers, in partnership with the Technical Lead.
Core Technical Contribution- Take ownership of complex architectural challenges, system designs, and critical feature development. Lead by example in engineering craftsmanship while collaborating closely with the team and the Technical Lead.
