Senior Software Engineer in Boise

A career with Gravity Payments is an opportunity to be on a collaborative team where creative leadership, passion for progress, and responsibility are paramount. Our team members focus and commit to providing for our clients and our community because we care deeply for others.

Success in this role looks like:

• Within three months, you understand the payment flows that power Gravity's business and are shipping production code into them.
• Within your first year, you are a reliable resource for PCI DSS audit activities -- contributing control implementations, automating evidence collection, and identifying scope boundaries.
• You are a technical anchor on the processing team -- someone whose architectural judgment and domain knowledge is trusted with difficult projects.
• You contribute to a positive engineering culture through direct, specific feedback in code review and pairing.
• You are an agent of positive change. When a process needs to be created, refined, or eliminated, you are a catalyst for that change.
• You bring generative AI tools into day-to-day engineering workflows and share learnings across teams to drive effective adoption of relevant new technologies.

Core Responsibilities

• Design, build, test, and deploy across Gravity's payments infrastructure: gateway services, device integrations (EMV terminals), transaction processing, and supporting systems. You own problems end-to-end, from business requirements through production operation.
• Manage and evolve AWS infrastructure through infrastructure-as-code. Maintain security posture of cloud infrastructure and drive best practices.
• Make architectural decisions collaboratively -- seek input, present trade-offs, and make sure the team understands the "why." Then commit and ship.
• Evaluate system health pragmatically. Address technical debt before it becomes a significant blocker or creates risk.
• Participate in incident response for payment processing systems -- root cause analysis, evidence preservation, remediation.
• Document systems, decisions, and operational procedures. We build resilient teams with shared knowledge -- no single points of failure.
• Conduct code reviews that are genuinely useful: catch real issues, teach domain context, and keep the team moving.

Required Skills

• Payment processing experience: processor and gateway integrations, transaction flows, EMV, device integrations, PCI compliance.
• Strong track record shipping production software with high autonomy.
• Infrastructure-as-code experience in production (Terraform, Pulumi, CloudFormation, or equivalent).
• Active use and healthy curiosity of AI-assisted development tools and workflows.
• Collaborative technical decision-making. You seek input, share reasoning, and build alignment.
• Secure development practices appropriate for a regulated environment: secrets management discipline, least‑privilege access patterns, secure handling of sensitive data in logs, storage, and transit. Understanding of change management controls -- audit trails, separation of duties in deployment.

Preferred Qualifications

• Production experience with Elixir/Phoenix or TypeScript/Node.js.
• Device integration experience: payment terminals, EMV certification, hardware communication protocols.
• Experience on small, high‑autonomy teams where you are expected to contribute broadly.

• Must have access to a wired internet connection and access to at least a 25 megabits per second (mbps) download and 20 mbps upload speed connection.

Benefits

• Compensation: Competitive wage with Profit Sharing. Base pay without commissions and a unique opportunity to earn a share in company success.
• Comprehensive Benefits: Medical, dental, and vision coverage.
• Financial Security: 401(k) retirement plan and voluntary life insurance.
• Wellbeing: Time off when you need it, supporting both personal and professional sustainability. Open PTO available after one year.
• Career Growth: Training, mentorship, and development opportunities.
• Support & Stability: Short-term & long-term coverage and wellness resources.

The salary for this position is $175,000 - $200,000. We may be open to negotiating outside of this range if the desired salary aligns with the needs of the candidate and the company.
