Senior Engineer (Full Stack)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Engineer (Full Stack) based in India.

This is a senior-level engineering opportunity focused on building reliable integrations and data products that connect a fundraising platform with the systems nonprofits depend <on.You>’ll operate as a problem solver, taking ownership of ambiguous challenges from discovery through implementation and long-term maintenance.The role combines backend and frontend engineering with API design, data movement, observability, and third-party <integrations.You>’ll work extensively with Ruby on Rails, PostgreSQL, REST APIs, webhooks, OAuth, and modern web technologies.Your work will directly influence data integrity, customer experience, and the reliability of critical integrations at <scale.You>’ll join a fully remote, globally distributed team with a flat structure and a strong emphasis on pragmatic, maintainable engineering.The environment encourages autonomy, thoughtful technical decisions, collaboration, and shipping meaningful improvements without unnecessary process.

Accountabilities

Own integrations end to end: Build, operate, and continuously improve CRM and large-scale data synchronization integrations, treating them as long-lived products rather than one-time projects.

Ensure reliable data movement: Design systems that safely transfer records between platforms while handling deduplication, partial failures, retries, idempotency, and interrupted processing.

Build observability into integrations: Develop monitoring, logging, error reporting, and diagnostic capabilities that make synchronization issues visible and actionable before they affect customers.

Design durable APIs and webhooks: Create thoughtful data models and public-facing interfaces, with careful consideration for versioning, pagination, naming conventions, and error handling.

Apply strong product judgment: Evaluate requirements through a customer-focused lens, challenge unnecessary complexity, and help prioritize engineering work based on customer value, feasibility, and impact.

Collaborate and deliver: Work closely with engineering, product, and support teams, contribute to code reviews, help resolve technical escalations, and balance delivery speed with long-term quality.

Maintain engineering knowledge: Keep developer documentation, internal guides, and technical references accurate and useful, particularly where historical architectural decisions affect current integrations.

Drive ambiguous problems to resolution: Determine what work is required to solve complex problems, make informed trade-offs, and take ownership through completion without relying on highly detailed specifications.

Requirements

• Strong experience designing, building, and consuming REST APIs, including practical judgment around versioning, pagination, and error semantics.
• Demonstrated experience integrating with third-party systems you do not control, including handling rate limits, retries, partial failures, idempotency, and webhook delivery.
• Proven ability to move data between systems with different or incompatible data models, including record mapping, deduplication, and reconciliation.
• Strong proficiency with Ruby and Ruby on Rails, including designing data models and Rails objects for medium-sized features.
• Solid PostgreSQL and SQL skills, including the ability to write complex operational and bulk queries and interpret PostgreSQL EXPLAIN output.
• Experience writing robust automated tests that validate application behavior rather than implementation details; familiarity with Minitest is preferred.
• Strong independent problem-solving skills, with a demonstrated ability to take ambiguous requirements, identify the underlying work, and deliver practical solutions.
• Ability to make thoughtful technical trade-offs while maintaining realistic expectations around timelines, complexity, and engineering quality.
• Team-oriented approach, including a willingness to support colleagues, unblock teammates, participate constructively in code reviews, and prioritize overall team effectiveness.
• Familiarity with frontend technologies such as JavaScript, Hotwire, Turbo, Stimulus, semantic HTML, and CSS is valuable for the full-stack nature of the position.
• Experience with OAuth, webhooks, relational databases, object-oriented programming, and MVC architectures is highly relevant.
• Strong written and verbal communication skills and the ability to work effectively in a distributed, remote environment.

Benefits

• Fully remote work from India.
• Annual salary of $52,200–$58,000 USD, depending on experience and location.
• Eligibility for an employee equity plan through stock options.
• Up to $1,500 reimbursement for home-office expenses and professional development.
• Generous paid time off, including 21 days of PTO, with birthday time included.
• 8 holidays of your choice and 2 paid volunteer days.
• Wellness program offering fitness and mindfulness classes.
• Opportunity to work with a globally distributed team in a flat, collaborative environment.
• Meaningful opportunity to build technology that supports nonprofit organizations and their fundraising efforts.
• Strong emphasis on autonomy, professional growth, engineering quality, and practical problem solving.
