Software EngineerSoftware Engineering

Mechanical Orchard builds Imogen, a modernization platform for rewriting the most critical and complex business applications—the systems that quietly run the world as we know it—so they can continue operating reliably while adapting to new challenges and opportunities. These are business-critical systems where reliability, safety, and correctness are paramount.

Delivery at Mechanical Orchard is where Imogen meets reality. Delivery teams work directly with customers and system integration partners in real production environments to modernize mainframe systems using Imogen. This work delivers customer outcomes while also shaping how the platform evolves, ensuring Imogen is grounded in real-world constraints, risks, and opportunities.

Our Delivery team operates in complex, ambiguous environments with high stakes. We balance long-term modernization outcomes with incremental, production-ready delivery; validate functional equivalence, performance, and operational readiness; and work closely with partners to enable durable handoff and long-term ownership. We value strong fundamentals, pragmatic use of AI, and close collaboration across roles and organizations. Our values are simple: Do the right thing. Do what works. Be kind.

The Role

As a Software Engineer in Delivery, you work hands-on with Imogen in complex, real customer environments—often where there is no established playbook. You help modernize production systems, validate approaches, and shape how Imogen is used, adopted, and improved.This is a collaborative, client-facing role. You’ll pair daily with teammates, work directly with customer engineers and partners, and contribute to systems that must be reliable, operable, and ready for long-term ownership.

Work with Imogen to modernize production mainframe systems in collaboration with customers and partners

Work as part of small, cross-functional XP teams, pairing daily and collaborating closely with product managers, designers, client engineers, partners, and internal platform teams

Lead and facilitate technical discovery sessions and workshops, including on-site with customers, to understand existing systems, align on risks, and shape delivery approaches

Apply XP engineering practices such as pair programming, TDD, refactoring, and CI/CD

Use and experiment with LLM-assisted coding tools, contributing to evolving best practices for AI use in software engineering at MO

Design and operate production systems with a focus on durability, operability, and eventual client and partner ownership, including participating in team on-call rotations

Execute delivery work in a way that enables partner engineers to independently deliver modernization efforts using Imogen over time

Collaborate closely with partner engineers through pairing, mentoring, and shared problem solving, and help codify reusable technical and operational patterns

Work flexibly across time zones when collaborating with partners based in the US and India

This role is client-facing and partner-facing; communication, facilitation and collaboration are core parts of the work

Much of the work involves legacy mainframe systems, often written in COBOL and JCL

Our technology organization has an on-call rotation essential to operating the systems we deliver

Pair programming is a foundational practice and may involve a learning curve

This role may include occasional international travel to client sites—typically a few times per year—to support kickoff, scoping, and collaborative workshops

Collaboration across time zones is part of the role, particularly with partners based in the UK and India

The ideal candidate is an experienced software engineer who enjoys solving complex, real-world problems in collaborative, delivery-focused teams. They are comfortable working hands-on in unfamiliar domains, learning legacy systems, and contributing to production software that must be reliable, operable, and ready for long-term ownership.

They bring experience working directly with customers or partners and are comfortable leading technical discussions, facilitating workshops, and navigating ambiguity in high-stakes environments. They value practices like pair programming, test-driven development, and continuous improvement, and enjoy working closely with product managers, designers, and other engineers.

They are excited about AI-assisted development and interested in operating at the bleeding edge of evolving best practices for LLM-based coding tools, while exercising sound engineering judgment. Strong communication skills, empathy, and a collaborative mindset are essential, as this role involves close partnership with teammates, customers, and external delivery partners.
