Senior Mobile Software Engineer | Contractor (Xico)

About This Role As a Senior Level Software Engineer, you'll play a key role in building and maintaining secure, scalable applications that support critical customer and business needs. You'll work across the stack—from designing backend services to implementing front‐end features—while collaborating closely with cross‐functional teams. This role is hands‐on: you'll translate requirements into well‐designed solutions, write production‐ready code, participate in code reviews, and contribute to the overall reliability and performance of our systems. You'll also help support our applications in production through on‐call rotations and proactive issue resolution. This position is idóneo for an engineer who enjoys solving real‐world problems, working in modern cloud environments, and contributing to systems end‐to‐end. You'll have the opportunity to deepen your technical expertise, influence design decisions, and grow within a supportive engineering culture. At Very the key distinction between mid, senior and lead roles is the scope and depth of your expertise and responsibility. As a senior, you have deep expertise in your area of specialization and can execute independently in your domain while interfacing with other software stacks. This is not an easy role. You'll work in complex domains, under real deadlines, and with clients who expect you to bring clarity, confidence, and results. If you find satisfaction in doing hard things well—solving tough problems, building real systems, and helping others rise to the challenge—you'll fit right in. As a client services organization, travel may be required up to 10% of the time. What You'll Be Working On Every engagement at Very is different, but they share one common theme: we build things that matter. From connected hardware and data systems to large‐scale web and AI‐driven platforms, you'll: Capture technical requirements and contribute to high‐level and low‐level design for software solutions using React‐Native and AWS. Write production‐grade code that meets high standards for maintainability, security, and observability. Implement testing strategies and automation across the stack. Collaborate across engineering, design, and product to deliver high‐quality outcomes. Identify and proactively address potential technical or operational risks before they impact customers. You'll operate in a modern, polyglot environment that includes: Frontend: React, Vite, TypeScript, REST API, WebSockets, Progressive Web Apps Mobile: React‐Native, Native iOS and Android, Expo, EAS, Kotlin, Tailwind Backend: Node.js, Python, FastAPI, Django, Celery Cloud‐AWS: Lambda, Fargate, RDS, ALB, WAF, CloudFront, CloudWatch, SQS, IoT Core DevOps: Claude Code, Docker, Terraform, Pulumi, GitHub Actions Databases: Postgres, Redis, Valkey, TimescaleDB, DynamoDB Testing: Playwright, Cypress, Pytest Observability: DataDog RUM, DataDog Logging, Request Tracing and Correlation Outcomes Deliver High‐Quality Features: Ship secure, reliable code that meets requirements, adheres to standards, and delivers measurable business value. Strengthen System Reliability: Improve observability, performance, and operational excellence across services and components. Support Cross‐Functional Delivery: Collaborate effectively with lead engineers, designers, PMs, and client stakeholders. Raise the Bar: Contribute to better patterns, tooling, and engineering standards across teams. Enhance Customer Success: Proactively identify and resolve technical issues that could impact system behavior or user experience. Responsibilities Take ownership of mobile development in projects. Work with lead mobile engineers to advance the mobile best practices. Leverage Claude to accelerate mobile development and integration with the design system. Support implementation of features across frontend, backend, and cloud components. Participate in technical design discussions and contribute to architectural decisions. Write clean, scalable, and secure code following Very's engineering standards. Create and maintain automated tests across all layers of the stack. Support deployments, CI/CD pipelines, logging, monitoring, and alerting. Participate in code reviews, offering constructive feedback that improves overall quality. Support documentation and knowledge sharing within teams. Requirements Experience 8+ years of professional software development experience. 4+ years of experience developing React‐Native mobile applications. Full software development lifecycle experience, including requirements, design, implementation, testing, deployment, and operations. Strong understanding of production‐grade system reliability, observability, and security. Client‐facing or consulting experience preferred but not required. Technical Skills Strong mobile experience in React‐Native, Expo, EAS. Strong experience with e2e testing. Fluency with frontend technologies including React, Vite, TypeScript, REST API, WebSockets. Extensive knowledge in supporting event‐driven cloud platforms in AWS including security, logging, monitoring, observability and performance at scale. Knowledge of state management libraries such as Redux, MobX, XState and Zustand. Ability to debug and modify CI/CD automation (GitHub Actions & Expo). Nice‐to‐have Strong mobile experience in Native iOS and Android, Kotlin, Tailwind. AWS experience in Lambda, Fargate, RDS, ALB, WAF, CloudFront, CloudWatch, SQS, IoT Core. Backend knowledge of Node.js, Python, FastAPI, and Django. Skilled in relational and non‐relational data modeling. Proficient in Docker and Terraform or Pulumi. Database experience including Postgres, Redis, Valkey, TimescaleDB, DynamoDB. Education BS or higher in Computer Science, Software Engineering, or related field. Location Primary residence in Colombia with proper work authorization. We do not sponsor work visas. This Role Is Likely NOT a Fit If You prefer working in a highly structured environment where processes rarely change. You are not comfortable working across the full stack, including cloud infrastructure and frontend components. You require constant supervision or detailed task breakdowns rather than owning complex problem domains independently. You are not interested in client‐facing work or measuring technical success by business outcomes. Compensation Base Compensation: USD $40–$60 per hour, commensurate with experience. #J-*****-Ljbffr Postúlate en Kit Empleo: kitempleo.com.mx/empleo/5vbx7x
