Senior Software Engineer, Voxie Inc

• This is a backend-focused role for an engineer who can take a rough integration requirement, ask the right questions, and ship a system that holds up at high message volume
• 5+ years of professional backend development experience with PHP (Laravel), TypeScript, or similar
• Proven experience building and maintaining third-party integrations: REST APIs, webhooks, OAuth, SFTP, and batch data exchange
• Experience with high-throughput or high-volume messaging systems
• Solid understanding of distributed systems, API design, and database design
• Working knowledge of AWS, particularly Lambda, RDS, DynamoDB, SQS, and SNS
• Experience with automated test frameworks and CI/CD pipelines
• Practical use of AI coding tools to ship faster, with the judgment to know where they help and where they don't
• Strong communication skills: comfortable gathering requirements from non-engineers and speaking directly with customer technical teams
• Our primary language is English, but we speak Portuguese, Spanish, Ukrainian, and French, so far!

Desirable

• The Senior Software Engineer builds and owns the integrations that connect Voxie's conversational platform to the systems our customers run their businesses on: CRMs, POS platforms, marketing tools, and messaging providers
• You will scope work directly with our sales engineers and solutions engineers, with third-party platform teams, and at times with a customer's own technical staff. Strong communication matters here as much as strong code
• Design, build, and maintain integrations with third-party platforms using REST APIs, webhooks, SFTP, and batch data pipelines
• Turn ambiguous requirements into working systems: gather what you need from sales engineers, solutions engineers, and partner platform teams, then build it
• Work directly with third-party providers and customers' engineering teams to scope, validate, and troubleshoot integrations
• Handle high-throughput messaging workloads with careful attention to rate limits, retries, idempotency, and failure recovery
• Design, develop, and maintain high-quality, testable, scalable backend systems in PHP and TypeScript
• Extend our distributed systems architecture for reliability, scalability, and cost efficiency
• Use AI tools to accelerate delivery and automate processes end to end, so your time goes to high-value orchestration and reliability work
• Write code that both humans and AI agents can understand, modify, and extend
• Build serverless and distributed solutions on AWS (Lambda, RDS, DynamoDB, SNS, SQS)
• Design systems for security, resilience, and operational efficiency
• Contribute to infrastructure-as-code and CI/CD automation
• Participate in Agile ceremonies and contribute to scoping and design discussions
• Partner with Product, Sales, and Customer Success to deliver integrations that close deals and keep customers
• Provide mentorship and code reviews that raise the team's engineering standard
• Build and maintain automated test suites with PHPUnit, Jest, and GitHub Actions
• Hold the line on testing, code review, and monitoring
