Work You'll Do

You are a hands-on full-stack developer who builds, tests, and ships reliable software as part of an agile engineering team. You contribute to the design and implementation of cloud-native applications and AI-augmented features, growing your technical depth across the stack. You will work alongside senior engineers to grow your technical skills while making meaningful contributions to our projects.

Key Responsibilities

• Design, build, test, and maintain scalable full-stack features across front-end and back-end systems, following project engineering standards and conventions.
• Write clean, well-documented, and maintainable code; participate in code reviews and contribute constructive technical feedback to peers.
• Develop and maintain back-end microservices and scalable APIs; implement CI/CD pipelines, containerized workloads, and infrastructure-as-code as part of client engagements.
• Integrate LLM APIs (OpenAI, Anthropic Claude, Google Gemini, Azure OpenAI) to build intelligent, context-aware features within client applications.
• Implement agentic AI patterns - tool-calling agents, RAG pipelines, prompt chaining, and memory management - within full-stack applications under senior engineer guidance.
• Collaborate on prototyping and iterating AI-powered workflows and automation solutions, contributing to the practice's growing AI delivery capability.
• Participate actively in code reviews, providing and incorporating constructive feedback.
• Collaborate with product managers, designers, and fellow engineers to translate requirements into technical solutions.
• Identify, diagnose, and resolve bugs and performance issues in development and production environments.
• Assist in breaking down technical requirements into well-scoped tasks and estimates.
• Support junior engineers through pairing, knowledge sharing, and informal mentorship.
• Write and maintain unit, integration, and end-to-end tests to ensure software reliability.
• Participate in on-call rotations and contribute to incident response and post-mortems.

A successful candidate would possess these skills:

• Ability to work independently and collaborate as part of a team
• Effective written and verbal communication skills
• Meticulous attention to detail and quality of work product
• Ability to build and sustain professional relationships
• Ability to lead projects or workstreams
• Ability to manage and prioritize multiple tasks in a fast-paced and dynamic environment
• Strong interpersonal skills and professional demeanor
• Ability to meet deadlines
• Ability to provide clear guidance to others

Qualifications

• 4-6 years of professional software engineering experience with a focus on full-stack development.
• 3+ years of full system lifecycle development experience, from requirements through production deployment.
• 3+ years of hands-on full-stack experience with proficiency in at least one back-end language (Python, Java, .NET, Go, or Node.js) and a modern front-end framework (React, Angular, or Vue.js).
• 2+ years in a client-facing development role, or a demonstrated ability to engage professionally with external stakeholders.
• 2+ years building and consuming RESTful APIs and/or GraphQL services in a professional, team-based delivery environment.
• Solid understanding of software engineering fundamentals including data structures, algorithms, and OOP principles.
• Familiarity with relational or NoSQL databases and comfort writing efficient queries.
• Working knowledge of version control systems (Git) and collaborative development workflows.
• Understanding of testing practices and experience writing automated test suites.
• Strong verbal and written communication skills with the ability to work effectively in a team environment.
• Working knowledge of at least one major cloud platform (AWS, Azure, or GCP), including deployment, managed services, and basic infrastructure configuration.
• Hands-on experience integrating at least one LLM platform or generative AI API (OpenAI, Azure OpenAI, Anthropic, Google Vertex AI, or equivalent).
• Bachelor's degree in computer science, Engineering, or a related discipline - or equivalent professional experience.
• Ability to travel up to 50% based on the work you do and the clients and industries/sectors you serv
• Limited immigration sponsorship may be available

In addition, successful Software Engineer II candidates will have the following preferred background:

• Experience with containerization and orchestration tools such as Docker and Kubernetes.
• Familiarity with CI/CD pipelines and DevOps practices.
• Experience working in an Agile/Scrum environment using tools like Jira or Linear.
• Contributions to open-source projects or a personal portfolio demonstrating technical initiative.
• Interest in mentoring others and taking on increased technical responsibility over time.
• Industry-recognized cloud certifications (AWS Certified Developer, Azure Developer Associate, GCP Professional Developer, or equivalent).

Wages + Salary

The wage range for this role takes into account the wide range of factors that are considered in making compensation decisions including but not limited to skill sets; experience and training; licensure and certifications; and other business and organizational needs.
