We are seeking strong, hands-on engineers with a proven track record of designing, building, shipping, and operating production-grade software systems.

Ideal candidates may come from full-stack, backend, distributed systems, platform, infrastructure, product engineering, solutions engineering, or AI-enabled software backgrounds.

These opportunities are particularly suited to engineers who can take ownership of complex technical problems, work across modern software stacks, and deliver reliable systems from architecture and implementation through deployment and production.

What You May Work On

• Design, build, and maintain production-grade applications, platforms, and backend services
• Develop scalable APIs, microservices, distributed services, and system integrations
• Build modern web applications and user-facing product experiences where relevant
• Design and optimize relational, NoSQL, caching, and data-processing systems
• Build and operate software in cloud and containerized environments
• Improve system scalability, performance, reliability, observability, and security
• Participate in architecture, system design, and technical decision-making
• Own features and services end-to-end from design through development, testing, deployment, and monitoring
• Build internal platforms, developer tooling, automation, and infrastructure where required
• Integrate third-party, enterprise, and customer systems
• Troubleshoot complex production and distributed-system issues
• Collaborate closely with product, engineering, infrastructure, and customer-facing teams
• Work with AI/ML-enabled products, LLM integrations, agents, or AI infrastructure where relevant.

What We’re Looking For

• 5+ years of professional software engineering experience building production-grade applications, platforms, or services
• Strong programming ability in one or more of:
• JavaScript / TypeScript
• Python
• Node.js
• Go
• Java
• C++
• or comparable modern languages
• Strong experience with backend services, APIs, microservices, or distributed systems
• Experience with modern frontend technologies such as React, Next.js, or similar is valuable for full-stack roles
• Experience with relational or NoSQL databases such as PostgreSQL, MySQL, MongoDB, Redis, DynamoDB, or similar
• Experience with a major cloud platform such as AWS, GCP, or Azure
• Familiarity with technologies such as Docker, Kubernetes, Terraform, CI/CD, Git, automated testing, and observability tooling
• Strong computer science and software-engineering fundamentals
• Strong system-design, debugging, and problem-solving capabilities
• Ability to take ownership of complex engineering problems and work independently
• Strong written and verbal communication skills

Particularly Valuable Experience

Experience in one or more of the following areas would be highly advantageous:

• Full-stack engineering
• Backend engineering
• Distributed systems
• Platform engineering
• Infrastructure / DevOps / SRE
• Product engineering
• Developer platforms or developer productivity
• High-scale APIs and microservices
• Event-driven systems such as Kafka or similar technologies
• Cloud-native architecture
• Enterprise integrations
• Solutions or customer-facing engineering
• Forward Deployed Engineering
• Security-sensitive or regulated systems
• High-growth SaaS or venture-backed technology environments

AI / ML Experience

Relevant experience may include:

• Production GenAI or LLM integrations
• AI-enabled application development
• RAG architectures
• AI agents or agentic workflows
• Model APIs such as OpenAI, Anthropic, Gemini, or similar
• Embeddings and vector databases
• AI orchestration frameworks
• AI infrastructure or model-serving platforms
• ML-enabled backend systems
• Production deployment of AI/ML capabilities

You do not need experience with every technology or specialization listed above.

We value strong engineering fundamentals, demonstrated technical depth, meaningful production experience, and the ability to learn and operate effectively across modern software systems.
