Job description

Arca.ph is recruiting a Senior Full-Stack Software Engineer on behalf of a client building cloud-based products and intelligent workflows for growing businesses. This is a fully remote opportunity open to candidates anywhere in the world who can work U.S. business hours.

In this role, you'll work with the client’s product and engineering team, contributing across the full stack and owning work from discovery through production.

Our client is hiring a Senior Full-Stack Software Engineer who can turn ambiguous product problems into scalable, maintainable software. You will work across modern web interfaces, APIs, backend services, data, and cloud infrastructure, with meaningful influence over architecture and engineering practice.

This role is a strong fit for an experienced product engineer who combines hands-on delivery with sound judgment: someone who can ship quickly, explain tradeoffs, improve systems over time, and help other engineers do their best work.

What you will own

• Design, build, test, release, and operate production features across the frontend, backend, data layer, and cloud environment.
• Create clear service boundaries, data models, APIs, and integration patterns that support growth without unnecessary complexity.
• Build accessible, responsive React and Next.js interfaces with strong performance, reusable components, and thoughtful product behavior.
• Develop reliable Node.js and Python services, REST or GraphQL APIs, background workflows, and third-party integrations.
• Help ship LLM-powered workflows and automation with appropriate evaluation, observability, human review, privacy controls, and failure handling.
• Improve automated testing, CI/CD, monitoring, incident response, security, reliability, and application performance.
• Modernize legacy components pragmatically while protecting customer experience and delivery momentum.
• Lead technical discussions, review code and designs, document decisions, mentor engineers, and raise the bar for engineering quality.
• Partner with Product, Design, Data, and business stakeholders to define scope, surface risks, and deliver customer outcomes.

What senior means here

You own outcomes, not tickets. You clarify the problem, propose an approach, deliver it, and follow through in production. You balance speed and durability, strengthen the team through thoughtful design and mentorship, and communicate risks and tradeoffs early.

What success looks like

Within 30 days, you understand the product, customers, architecture, delivery process, and highest-leverage technical risks. Within 90 days, you have shipped a meaningful production feature and contributed to technical direction. Within 6-12 months, you own a major product or system area, have improved reliability or delivery velocity, and are actively shaping engineering standards.

Remote work expectations

This is a full-time remote role, working with a U.S.-based product team. You must maintain hours of overlap with U.S. Eastern Time. Strong written communication, dependable follow-through, and comfort with asynchronous work are essential. Final employment or contractor structure depends on the hiring entity and candidate location.

Must-have requirements

• 6+ years of professional software engineering experience, including substantial ownership of production systems or major product features
• Strong backend engineering skills in Node.js and/or Python, including API design, asynchronous workflows, error handling, and service-level testing
• Experience with PostgreSQL or another relational database, including schema design, query performance, migrations, and data integrity
• Experience designing and consuming REST APIs; GraphQL experience is valuable
• Production experience with AWS or GCP, Docker, and CI/CD pipelines
• Practical command of automated testing, code review, debugging, performance optimization, observability, and secure development
• Strong product judgment, written communication, and ability to work independently through ambiguity in a distributed team

Nice-to-have requirements

• Production experience with LLM-powered or AI-assisted features, including RAG, tool use, evaluation, and guardrails
• Java and Spring Boot or C# and .NET experience
• Terraform or other infrastructure-as-code tools
• Kubernetes, Redis, Elasticsearch, Kafka, or event-driven architectures
• B2B SaaS, workflow automation, multi-tenant systems, real-time applications, or regulated customer data
• Early-stage or fast-growing company experience
• A track record of mentorship, technical leadership, documentation, or architectural improvement
