Senior Modeling & Optimization Engineer

About the role

You'll own analytical delivery on Mytra's customer engagements — using operations research methods (simulation, optimization, and data science) to solve customer design problems and validate warehouse automation solutions. This is a delivery-owner role, not a support seat: you'll take engagements end-to-end — analyzing operational data, modeling system behavior, running design experiments, and translating findings into recommendations that land deals and shape what Mytra builds next — with the autonomy and judgment to run them without close direction.

A defining part of the job is working across two modeling modes and knowing when to use each: fast, low-setup models for rapid design iteration early in a deal, and deeper, higher-fidelity validation when a decision warrants it. Balancing speed against fidelity — and building the tooling that lets others run the fast mode themselves — is central to the role.

This role sits within the Modeling & Optimization team, the technical and analytical backbone of Mytra's commercial pipeline. M&O's mandate is to make the commercial org continuously better — and a central way we do that is by building tools that hand capability back to solutions engineers and designers so analytical work isn't gated on our team. You'll both deliver the hard analysis and work yourself out of being the bottleneck on the routine parts.

What you’ll do:

• Own analytical delivery on customer engagements end-to-end — from operational data through to recommendations — with the judgment to scope depth appropriately and run engagements without close direction.
• Work across two modeling modes: fast, low-setup models for rapid design iteration, and deeper planner-in-the-loop validation for higher-fidelity de-risking — and exercise judgment on when each is warranted.
• Analyze customer operational data — order profiles, SKU demand patterns, throughput characteristics, and work schedules — to inform system design and sizing decisions.
• Design, build, and execute simulation models (discrete-event simulation, scoped scenario models) to validate warehouse designs and quantify system performance for customer proposals.
• Develop optimization models and recommender logic to support layout decisions, fleet sizing, zoning strategies, and other design trade-offs.
• Build and hand off self-serve tooling to the commercial org — so solutions engineers and designers can run routine analysis themselves and the team is not the bottleneck on every study.
• Make sense of data across customers and solutions, and help translate what we see on the customer side into product requirements — so this signal reaches product without solutions engineers carrying the full analytical load.
• Conduct structured experiments, sensitivity analyses, and design space explorations; communicate results and actionable recommendations to technical and non-technical audiences.
• Build repeatable analytical workflows, scenario configurations, and validation frameworks that raise the baseline capability of the broader commercial engineering org.

Ideal Candidates

• 5+ years of industry or relevant experience.
• A track record of owning analytical work end-to-end and operating with autonomy — comfortable being accountable for delivery, not just contributing to it.
• Strong proficiency in Python, including object-oriented design and building production-grade code.
• Experience with at least two of: discrete-event simulation, mathematical optimization, statistical modeling, or applied data science.
• Range, and an appetite for it: this role flexes across analysis, tooling, and process as the commercial org's needs evolve, and you're energized rather than frustrated by work that changes shape.
• A bias toward building yourself out of repetitive work — you measure success partly by how much you've enabled others to self-serve.
• Ability to design experiments, analyze data, and communicate insights clearly to technical and non-technical audiences.
• Solid engineering fundamentals (systems thinking, algorithmic reasoning, version control, testing).
• Comfort working directly with customers or in customer-adjacent roles where your analysis informs high-stakes decisions.

Nice to have:

• Professional experience in simulation engineering or modeling/operations research teams.
• Familiarity with DES frameworks (SimPy, salabim, internal engines, or equivalent).
• Background in warehouse automation, robotics, manufacturing systems, industrial engineering, or related fields.
• Experience with data visualization (Plotly, Matplotlib, Dash, etc.)
• Experience contributing to simulation platforms, modeling libraries, or internal tooling.

A Final Note:

If this role excites you, we encourage you to apply — even if you don’t check every box. At Mytra, we build bots, but we hire humans. We value thoughtful challengers who communicate with clarity and respect, and we’re lifelong learners committed to getting better every day. We move fast, learn faster, and show up for each other under pressure. The best outcomes come from diverse perspectives working together to build something meaningful and built to last
