ABOUT DELTEK
Deltek is the leading global provider of software and solutions for project-based businesses, serving government contractors, professional services firms, and architecture & engineering companies. Our products help customers manage the full project lifecycle — from winning work and planning resources to executing delivery and getting paid.
The Support Operations Technical Solutions team sits inside Deltek's Customer Success organization. We build and maintain the internal tooling, integrations, and AI-powered workflows that enable Deltek's support and customer success teams to operate at scale — think intelligent case routing, knowledge-base agents, data pipelines between Salesforce, Gainsight, and Oracle Service Cloud, and automation that removes manual work from high-volume support processes.
THE ROLE
We are looking for a System Engineer (IC2) to join our Technical Solutions team based in India. This is a hands-on engineering role, you will build, integrate, and support the systems that power our customer-facing and internal support operations.
In your first year, you can expect to:
- Build and maintain integrations between support platforms (Oracle Service Cloud, Salesforce, Gainsight) using PHP, JavaScript, and Workato
- Contribute to AI-assisted workflow automation — including LLM-based tools and intelligent routing solutions already in production
- Write and optimize SQL queries against our operational data stores to power dashboards, reports, and automated triggers
- Troubleshoot issues across the full stack: front-end, API layer, back-end logic, and database and document root cause findings
- Work in a sprint-based environment alongside engineers, CS operations leads, and product stakeholders across the US and India
This role is well-suited for someone who is early in their career but already has real project or production experience. You will work with guidance from senior engineers while taking genuine ownership of defined workstreams. The expectation is not that you know everything on day one — it is that you are technically curious, structured in your thinking, and driven to ship things that work.
WHAT WE'RE LOOKING FOR
Must-Have Technical Skills
- PHP and JavaScript: Hands-on experience building or maintaining web applications, APIs, or internal tools. You have written code that went somewhere beyond your laptop.
- REST/SOAP APIs and Web Services: You understand how system-to-system data flows work and have built or consumed integrations in a real context.
- Relational databases and SQL: You can write optimized queries, understand joins and indexes, and are comfortable reading a schema you didn't design.
- Full-stack troubleshooting: When something breaks, you know how to methodically trace the issue across front-end, back-end, and database layers — not just escalate it.
- Documentation: You can translate what you built into clear written artifacts — requirements, workflow diagrams, solution designs — that a non-engineer can follow.
- Agile/sprint delivery: You have worked in a structured sprint environment and are comfortable with ceremonies, tickets, and incremental delivery.
Must-Have Soft Skills
- Root-cause orientation: You don't patch symptoms and move on. You want to understand why something broke before deciding how to fix it.
- Self-driven with good judgment: You can manage your own time on a defined problem, identify when you're stuck and need input, and flag risks before they become blockers.
- Clear communicator across audiences: You can explain a technical problem to a non-technical stakeholder and a design decision to a senior engineer — in writing and in a call.
- Collaborative: You work well with people you've never met in person, across time zones, and with stakeholders who don't share your technical background.
Nice-to-Have Skills
The following are not required for the role, but candidates with depth in any of these areas will stand out. Listed in rough order of relevance to this team's current work:
Oracle Service Cloud
Workato / iPaaS
Salesforce
Gainsight
AI / LLM integration
Snowflake
Microsoft Power BI
Microsoft Power Apps
Cloud-native development
Experience with AI tools (GitHub Copilot, LLM APIs, automation agents) used in an operational or product context — not just personal experimentation — is a genuine plus for this team.
RESPONSIBILITIES
At the IC2 level, you will primarily execute within defined frameworks and grow your independent scope over time. The following reflects what you will own and contribute to:
Build & Integrate
- Build and maintain AI-enabled workflows, platform integrations, and internal tools using PHP, JavaScript, Workato, and Web Services
- Develop prototypes and proofs of concept; contribute to production deployments under senior guidance
- Implement and test integrations between Deltek's support platforms and internal data systems
Analyse & Solve
- Break down defined problems into actionable tasks; identify risks, dependencies, and edge cases before they surface in production
- Troubleshoot complex issues across the full stack and document root cause findings clearly
- Investigate stakeholder-reported issues to identify whether the problem is technical, process-related, or both
Operate & Improve
- Follow established governance, architecture, and deployment processes; raise improvement suggestions through proper channels
- Write and maintain documentation for systems, workflows, business rules, and solution designs
- Participate actively in sprint ceremonies; manage your own tasks and flag blockers early
- Demonstrate continuous learning in AI, automation, and integration technologies — this space moves fast and curiosity is part of the job
QUALIFICATIONS
- Education: Bachelor's degree in Computer Science, Information Technology, Engineering, or a related technical discipline. Equivalent practical experience considered.
- Experience: 1–3 years of hands-on experience in software engineering, systems integration, or a closely related field. Internship and co-op experience counts if it involved real production systems.
- Coding: Demonstrable PHP and/or JavaScript experience — a portfolio, GitHub profile, or code sample you can speak to will strengthen your application.
- Collaboration model: Comfortable working remotely with distributed teams. The role requires regular overlap with US East/Central time zones (approximately 6:30 PM – 10:30 PM IST for at least part of the week).
- Language: Strong written and spoken English is essential — much of the collaboration with stakeholders and senior engineers happens asynchronously in writing.
WHAT TO EXPECT WORKING HERE
- A small, technically-focused team where your work is visible and your contributions are directly tied to outcomes customers feel
- Exposure to production AI/LLM systems, not just theoretical discussions about AI
- A culture that values root-cause thinking and good documentation over heroics and quick fixes
- Growth path: engineers who demonstrate technical depth and ownership at IC2 have a clear track toward IC3 (mid-level) scope within 18–24 months
- Regular 1:1s and structured feedback — this team invests in making you better, not just keeping you busy
